The return value is the result of invoking the ToString method of the underlying type of value.

The following example converts each element in an object array to its equivalent string representation.

object[] values = { false, 12.63m, new DateTime(2009, 6, 1, 6, 32, 15), 16.09e-12,
                    'Z', 15.15322, SByte.MinValue, Int32.MaxValue };
string result;

foreach (object value in values)
   result = Convert.ToString(value);
   Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                        value.GetType().Name, value,
                        result.GetType().Name, result);
// The example displays the following output: 
//    Converted the Boolean value False to the String value False. 
//    Converted the Decimal value 12.63 to the String value 12.63. 
//    Converted the DateTime value 6/1/2009 06:32:15 AM to the String value 6/1/2009 06:32:15 AM.
