The following example converts a Double to a String.

public void ConvertDoubleString(double doubleVal) {

	string	stringVal;     

	// A conversion from Double to string cannot overflow.       
	stringVal = System.Convert.ToString(doubleVal);
	System.Console.WriteLine("{0} as a string is: {1}",
		doubleVal, stringVal);

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