Hi,
there is no specific control for uploading file in windows application.
But you can do same functionality using below method:
(1) first take one button and textbox control.
(2) then add following code in your .cs file.
OpenFileDialog dlg = new OpenFileDialog();
[3]add following code in buttons click event.
dlg.Filter = "Audio File (*.mp3, *.wav)|*.mp3*;*.wav";
if (dlg.ShowDialog() == DialogResult.OK)
txtBox1.Text = dlg.FileName;
(4)show by this you can get filename in your textbox.
(5)now when you submit your form then write below code on your submit buttons click event.
FileInfo str = new FileInfo(dlg.FileName );
File.Copy(txtBox1.Text ,Application.StartupPath +"\\"+str.Name);
txtAodioPath.Text = Application.StartupPath + "\\" + str.Name;
(6)Now run your application. and check this functionality for uploading file.
