Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public string FileName { get; }

Property Value

Type: System.String

A string that specifies the name of a file on a client to upload using the FileUpload.

Gets the name of a file on a client to upload using the FileUpload control. The file name that the FileName property returns does not include the path of the file on the client.

The following example demonstrates how to create a FileUpload control that saves files to a path that is specified in code. The FileName property is used to get the name of the file to upload. The SaveAs method is called to save the file to the specified path on the server, using the same name the file has on the client. Note that this example demonstrates the basic syntax for this control, but does not demonstrate all the necessary error checking that should be done before saving the file. For a more complete example, see SaveAs.

  protected void UploadButton_Click(object sender, EventArgs e)
    // Specify the path on the server to
    // save the uploaded file to.
    String savePath = @"c:\temp\uploads\";

    // Before attempting to perform operations
    // on the file, verify that the FileUpload 
    // control contains a file.
    if (FileUpload1.HasFile)
      // Get the name of the file to upload.
      String fileName = FileUpload1.FileName;

      // Append the name of the file to upload to the path.
      savePath += fileName;

      // Call the SaveAs method to save the 
      // uploaded file to the specified path.
      // This example does not perform all
      // the necessary error checking.               
      // If a file with the same name
      // already exists in the specified path,  
      // the uploaded file overwrites it.

      // Notify the user of the name of the file
      // was saved under.
      UploadStatusLabel.Text = "Your file was saved as " + fileName;
      // Notify the user that a file was not uploaded.
      UploadStatusLabel.Text = "You did not specify a file to upload.";
