net CF

I need to use substring to capture the mid of a string.

txtpart.Text = "ab12345678cde";
string item = txtpart.Text.Substring(2,8);

Which the output should be 12345678.

But it always throws this Exception

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Is there any function other than substring?
