Solution 2

To do this, you must handle the FileOK [^] event of your OpenFileDialog. Inside your event handler, you can use Path.GetExtension[^] to get the extension of the filename.

Use like this..

C#

if (fd.ShowDialog() == DialogResult.OK)
 {
     string str = fd.FileName;                    
     string strExt = System.IO.Path.GetExtension(str);


     if(strExt == ".txt")
     {
        //do your stuff
     }
     else if (strExt == ".rtf")
     {
        //do your stuff
     }

Use this:

C#

textBox1.Text = OpenFileDialog.SafeFileName;
string constr = Path.GetExtension(fd);
if(constr == ".xlsx")//code to compare extension
{
     constr = @"Provider=Microsoft.Jet.OLEDB.12.0;Data Source= '" + textBox1.Text + "';Extended Properties='Excel 12.0;HDR=Yes;'";
}
else if(constr == ".xls")
{
      constr = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= '" + textBox1.Text + "';Extended Properties='Excel 4.0;HDR=Yes;'";
}
