Type.GetTypeCode Method

Gets the underlying type code of the specified Type.

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

Public Shared Function GetTypeCode ( _
	type As Type _
) As TypeCode


Type: System.Type
The type whose underlying type code to get.

Return Value

Type: System.TypeCode
The code of the underlying type.

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.

Sub WriteObjectInfo(ByVal testObject As Object)
    Dim typeCode As TypeCode = Type.GetTypeCode(testObject.GetType())

    Select Case typeCode
        Case typeCode.Boolean
            Console.WriteLine("Boolean: {0}", testObject)

        Case typeCode.Double
            Console.WriteLine("Double: {0}", testObject)

        Case Else
            Console.WriteLine("{0}: {1}", typeCode.ToString(), testObject)
    End Select
End Sub
