Thanks for any help

Plzzz help me guys!!!!!!!!!:(

please give some help for get file names

The open file dialog returns a file name.
Directory.GetFiles expects a path to a directory, not a file.
Use the folderBrowserDialog instead, something like this:

private System.Windows.Forms.FolderBrowserDialog folderBrowserDialog1;
this.folderBrowserDialog1 = new System.Windows.Forms.FolderBrowserDialog();
if (this.folderBrowserDialog1.ShowDialog() == DialogResult.OK)
                string folderName = folderBrowserDialog1.SelectedPath;
                string[] names = Directory.GetFiles(folderName);
                //more code...
