>Can you provide the code..I want to access network folder and upload to it..
You can use the OpenFileDialog like this:
string Pfad = string.Empty;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
if(openFileDialog1.ShowDialog() == DialogResult.OK)
Pfad = openFileDialog1.FileName;
After the dialog is opened, just choose your network server and click on "Save"
