The File uploading has always been a very tedious task for the web developer community. Either we have to use a third party component or write numerous lines of code. But with ASP.NET, uploading files become extremely easy. Now it can be done with a small amount of code lines with the FileUpload control.
In this article, I am going to show you how you can upload a file through ASP.NET.

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 = "Uploading Complete."
End If
End Sub

<br /><br />
<asp:label id=lblMsg runat="server" />
<input id="Button1" type=button value="Upload" OnServerClick="Upload"

</form>
</body>
When you run this application then the window will look like this:
Now click on the Browse button to select a file for uploading. After selecting the file, click on upload button and you will get the message after completion of file uploading.
