SaveFileDialog: Remove All Files option

I do not want to have the "All File" come up as an option in the savefiledialog box. What is the correct format below? I get an error when I remove "All Files"?

 SaveFileDialog saveFileDialog1 = new SaveFileDialog();             

saveFileDialog1.InitialDirectory = @"C:\";           

  saveFileDialog1.Title = "Save EasyTimesheet CSV";             

saveFileDialog1.DefaultExt = "csv";            

 saveFileDialog1.Filter = "CSV files (*.csv)|*.csv|All files (*.*)|*.*";             

saveFileDialog1.FilterIndex = 2;            

 saveFileDialog1.FileName = filenameFormat;
