Type.GetTypeCode Method (Type)

 

Gets the underlying type code of the specified Type.

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

public static TypeCode GetTypeCode(
	Type type
)

Parameters

type
Type: System.Type

The type whose underlying type code to get.

Return Value

Type: System.TypeCode

The code of the underlying type, or Empty if type is null.

When you inherit from Type, you can change the behavior of this method by overriding the GetTypeCodeImpl method.

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;
    }
}
