This article will show you how you can get the uploaded file
size in asp.net using c#.net and vb.net. In this article I will I have used
asp.net, C#.net, Vb.Net, fileupload control and button control.

Now generate the button click event and add the below code.
C#.Net
///
/// Button click event to get uploaded file size
///
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
decimal filesize = ((FileUpload1.PostedFile.ContentLength) / 1024) / 1024;
lblmessage.Text = "Uploaded File Size Is : " + filesize.ToString() + " MB";
}
else
{
lblmessage.Text = "Please select file.";
}
}
|
VB.Net
'''
''' Button click event to get uploaded file size
'''
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
If FileUpload1.HasFile Then
Dim filesize As Decimal = ((FileUpload1.PostedFile.ContentLength) / 1024) / 1024
lblmessage.Text = "Uploaded File Size Is : " + filesize.ToString() + " MB"
Else
lblmessage.Text = "Please select file."
End If
End Sub
|
But before this we will make a configuration change. Add the
below setting in web.config. This configuration we are adding to upload the file with large size.
|
<system.web>
<httpRuntime executionTimeout="240" maxRequestLength="20480" />
</system.web>
|
In above code whatever data we will get will be in byte so I
have converted it into MB by dividing it by 1024. So check the final output. So here is the uploaded file detail
Now select it and click on upload.
