Supported by the .NET Compact FrameworkSupported by the XNA FrameworkStringA sealed class type representing Unicode character strings.

Call the GetTypeCode method on classes that implement the IConvertible interface to obtain the type code for an instance of that class.

Otherwise, call an object's GetType method to obtain its Type object, then call the Type object's GetTypeCode method to obtain the object's type code.

The following code example demonstrates how the TypeCode enumeration can be used. In a decision block inside the WriteObjectInfo method, the TypeCode of an Object parameter is examined, and an appropriate message is written to the console.

static void WriteObjectInfo(object testObject)
{
    TypeCode    typeCode = Type.GetTypeCode( testObject.GetType() );

    switch( typeCode )
    {
        case TypeCode.Boolean:
            Console.WriteLine("Boolean: {0}", testObject);
            break;

        case TypeCode.Double:
            Console.WriteLine("Double: {0}", testObject);
            break;

        default:
            Console.WriteLine("{0}: {1}", typeCode.ToString(), testObject);
            break;
    }
}
