Example

```
 string strFileName=string.Empty;                       //creationg object of SaveFileDialogOpenFileDialog openFileDialog1= new OpenFileDialog();//setting filter of open file dialog box  openFileDialog1.Filter= "Text file|*.txt";//checking whether open button is clicked or not   if (openFileDialog1.ShowDialog()== DialogResult.OK)     {//storing filename opened through openfiledialog box.      strFileName = openFileDialog1.FileName;//creating reader to read open file.     System.IO.StreamReader sr = new System.IO.StreamReader(openFileDialog1.FileName);//displaying file contents in message box.      MessageBox.Show(sr.ReadToEnd());//closing stream reader.                sr.Close();    }
