How to Upload files in ASP .NET

Asking the user to upload a file to the server is a very very common task in most of the web applications. In classic ASP, uploading file was a very difficult task, since we need a third party component or we need to write our component to upload file from client to the server. In ASP .NET Uploading a file from client to the web server is so easy. To be precise, we can get this done in two lines of code. Yes, two lines of code. In this article, we will be looking into the following:

How to Upload a file from Client to the Web server in ASP .NET?

How to give a different name to the file saved to the web server?

How to know the size of the file uploaded by the user?

How to control the size of file uploaded to the web server?

How to Upload a file from Client to the Web server in ASP .NET?

First of all, we need a HTML server control to allow the user to select the file. This is nothing but the same old <input tag, with the type set to File, such as <input type=file id=myFile runat=server />. This will give you the textbox and a browse button. Once you have this, the user can select any file from their computer (or even from a network). Then, in the Server side, we need the following line to save the file to the Web Server.

myFile.PostedFile.SaveAs("DestinationPath")

Example: Uploading a File in ASP .NET

<html>
<head>
<script language="VB" runat="server">

Sub Upload(Source As Object, e As EventArgs)

   If Not (myFile.PostedFile Is Nothing) Then

      Dim intFileNameLength as Integer
      Dim strFileNamePath as String
      Dim strFileNameOnly as String

      'Logic to find the FileName (excluding the path)
      strFileNamePath = MyFile.PostedFile.FileName
      intFileNameLength = Instr(1, StrReverse(strFileNamePath), "\")
      strFileNameOnly = Mid(strFileNamePath, (Len(strFileNamePath)-intFileNameLength)+2)

      myFile.PostedFile.SaveAs("c:\inetpub\wwwroot\yourwebapp\upload\" & strFileNameOnly)
      lblMsg.Text = "File Upload Success."

   End If
End Sub
</script>

</head>
<body>

<h3>File Upload</h3>

<form enctype="multipart/form-data" runat="server">
   File: <input id="myFile" type="file" runat="server">
   <asp:label id=lblMsg runat="server" />
   <input type=button value="Upload" OnServerClick="Upload" runat="server">
</form>

</body>
</html>

Test this Script

In the above example, you should note that, in the FORM tag, we have set the ectype to "multipart/form-data". This is another important aspect while uploading a file to the web server. We have a Input tag which is of type file. Then we have a button called "Upload". On the onclick of the button, you can see that, we are using some string functions to find the FileName (excluding the path). Finally, we invoke the method SaveAs to save the file (upload) in the web server.

How to retrieve the properties of file uploaded by the user?

We can retrieve some of the interesting and useful properties of the file that is uploaded to the webserver. The PostedFile provides us with three important properties, such as FileName, ContentType and ContentLength. In our previous example, we already saw, how to use the property, FileName? Now, we will see, how to know the size of the file uploaded, and how to know the contentType of the file uploaded.

The following line of code retrieves the ContentType of the file uploaded.

lblFileContentType.Text = MyFile.PostedFile.ContentType

The following line of code retrieves the Size of the file uploaded.

lblFileSize.Text = CStr(MyFile.PostedFile.ContentLength)
Now, we will see an example which uses this property.

Example: Uploading a File in ASP .NET

<html>
<head>
<script language="VB" runat="server">

Sub Upload(Source As Object, e As EventArgs)

   If Not (myFile.PostedFile Is Nothing) Then

      Dim intFileNameLength as Integer
      Dim strFileNamePath as String
      Dim strFileNameOnly as String

      'Logic to find the FileName (excluding the path)
      strFileNamePath = MyFile.PostedFile.FileName
      intFileNameLength = Instr(1, StrReverse(strFileNamePath), "\")
      strFileNameOnly = Mid(strFileNamePath, (Len(strFileNamePath)-intFileNameLength)+2)

      myFile.PostedFile.SaveAs("c:\inetpub\wwwroot\yourwebapp\upload\" & strFileNameOnly)
      lblMsg.Text = "File Upload Success."
   lblFileContentType.Text = "Content type: " & MyFile.PostedFile.ContentType
   lblFileSize.Text = "File size: " & CStr(MyFile.PostedFile.ContentLength) & " bytes"

   End If
End Sub
</script>

</head>
<body>

<h3>File Upload</h3>

<form enctype="multipart/form-data" runat="server">
   File: <input id="myFile" type="file" runat="server">    <input type=button value="Upload" OnServerClick="Upload" runat="server">
   <asp:label id=lblMsg runat="server" />
   <asp:label id=lblFileContentType runat="server" />
   <asp:label id=lblFileSize runat="server" />
</form>

</body>
</html>

Test this Script

How to control the size of file uploaded to the web server?

While uploading a file to the web server, we have a limit of 4MB by default. We can either decrease or increase this value. The value is set in the key, maxRequestLength of machine config file.

There is a maxRequestLength limit in the machine.config file (look for the <system.web> section), in the httpRuntime settings that you need to alter/raise if you want to accept anything larger than 4Mb. These are the standard settings for the httpRuntime:

<httpRuntime executionTimeout="90" maxRequestLength="4096"
useFullyQualifiedRedirectUrl="false" minFreeThreads="8"
minLocalRequestFreeThreads="4" appRequestQueueLimit="100"/>

This code is awesome but I'm getting "Logon failure and bad password" error whenever it's trying to get pass this line:

txtFileUpload.PostedFile.SaveAs(destPath & fname)

txtFileUpload being the id of the input control. Did anyone have this issue before? I appreciate any help.

Title: Uploading multiple files
Name: Eric Barr

Like many others here, I was trying to figure out how to upload multiple files at once without requiring the user to browse to every single file. I couldn't figure out how to do it without a file input field for each file, but since I knew the names of the files, I thought I could just make several file input fields and pre-populate the text boxes with the file paths. But then I got an error saying that the value of the file inputs was not settable. After looking around I unfortunately read this on a site:
"The problem is that the "value" property for this tag is read only. the only mean to fill this field with the value is having the user select a file. This is done for safety reason as otherwise you could upload files from a web client without user permission. And the only mean to upload a local file (with HTML alone) is to use this
tag.
"

I didn't double check anywhere else to confirm that, but it makes a lot of sense. It would be a big security hole if you could upload files from a computer withouth the user acknowledging each file.

Here is the page with that quote.

No doubt that this article is helpful but, my requirement is to upload multiple files into the application server!
I feel that some configuration needs to be done to the IIS inorder to do this.
I would be grateful to you,if you could solve this problem.

What about being able to upload more than "A" file at the time?
I have found examples of "HARDCODED" number of files that will
use A HARDCODED number of File Input HTML Web controls on
a WEB Form, that allow each to BROWSE and singly select each
file, then one UPLOAD button!

What I would like to see is a HTML WEB Control that will do that?

Some clients have medical images that constitute of a folder with
the subject's name and in the folder each slice (such as MRI images)
is in a file. Thus, typical images have 60 to 200 slices, each one stored
in a file. Thus, what about uploading a folder? That means that the BROWSE
should allow the selection of a folder and the UPLOAD should take care of
uploading ALL the files in the folder!

I would greatly appreciate your feedback.

Thank you,

The code here works fine but the problem is, when you press F5, it continues uploading!
Next, you cannot upload 2 files with same name because when doing so, there is just one file only!
So upload in ASP.NET is not the right choice!
Please help me out if you could solve these problems.
Thank you
