Converts the value of the specified object to its equivalent string representation.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public static string ToString(
	object value


Type: System.Object

An object that supplies the value to convert, or null.

Return Value

Type: System.String

The string representation of value, or String.Empty if value is null.

To convert value to its string representation, the method tries to call the IConvertible.ToString implementation of value. If value does not implement the IConvertible interface, the method tries to call the IFormattable.ToString implementation of value. If value does not implement the IFormattable interface, the method calls 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.
//    Converted the Double value 1.609E-11 to the String value 1.609E-11.
//    Converted the Char value Z to the String value Z.
//    Converted the Double value 15.15322 to the String value 15.15322.
//    Converted the SByte value -128 to the String value -128.
//    Converted the Int32 value 2147483647 to the String value 2147483647.
