The following code sample illustrates the conversion of a Char value to an Int64, using ToInt64.

public void ConvertLongChar(long longVal)
   char charVal = 'a';

      charVal = System.Convert.ToChar(longVal);
      outputBlock.Text += String.Format("{0} as a char is {1}",
         longVal, charVal) + "\n";
   catch (System.OverflowException)
      outputBlock.Text += String.Format(
         "Overflow in long-to-char conversion.") + "\n";

   // A conversion from Char to long cannot overflow.
   longVal = System.Convert.ToInt64(charVal);
   outputBlock.Text += String.Format("{0} as an Int64 is {1}",
      charVal, longVal) + "\n";
