.NET comes with great features. Anymore your do not need any additional code libraries to upload files to your web server. Microsoft.NET includes itself a file upload wizard. Now we will examined and play with this tool. I've used Visual Web Developer 2008 and ASP.NET 3.5 to create this sample application.

First we need to create a new web form and place FileUpload control on page. Drop a button and name it as Upload. Also drop a label and named as lblMsg to handle any message. Our file upload control name will be inputFileUpload. But you may rename anything in this sampel application.

 

After dropping and naming everything, your page must look like similiar this screen. Now let's pass code behind and add following code to your code page. To access code behind, simply double click on Upload button. Enter following code:

Protected Sub uploadButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uploadButton.Click

Dim strPath As String = Server.MapPath("uploads\")
Dim fileName As String
Try
If inputFileUpload.HasFile Then
fileName = inputFileUpload.FileName
inputFileUpload.SaveAs(strPath + fileName)
lblMsg.Text = "File uploaded!
File Name:" & fileName
Else
lblMsg.Text = "You did not upload anything!"
End If
Catch ex As Exception
lblMsg.Text = ex.ToString
End Try

End Sub

Now run application pressing F5 on keyboard. Ok, that was really simple and we have typed less code. We have saved file as original name but you may change file and path. All you need is to play with strParh and fileName variables.

Happy Coding!
