The following code sample illustrates the conversion of a Double to a String, using ToString.


public void ConvertDoubleString(double doubleVal)
{
   string stringVal;

   // A conversion from Double to string cannot overflow.       
   stringVal = System.Convert.ToString(doubleVal);
   outputBlock.Text += String.Format("{0} as a string is: {1}",
      doubleVal, stringVal) + "\n";

   try
   {
      doubleVal = System.Convert.ToDouble(stringVal);
      outputBlock.Text += String.Format("{0} as a double is: {1}",
         stringVal, doubleVal) + "\n";
   }
   catch (System.OverflowException)
   {
      outputBlock.Text += String.Format(
         "Conversion from string-to-double overflowed.") + "\n";
   }
   catch (System.FormatException)
   {
      outputBlock.Text += String.Format(
         "The string was not formatted as a double.") + "\n";
   }
   catch (System.ArgumentException)
   {
      outputBlock.Text += String.Format(
         "The string pointed to null.") + "\n";
   }
}
