'Declaration
Public Shared Function GetTypeCode ( _
	type As Type _
) As TypeCode
'Usage

	type : Type
) : TypeCode
Not applicable.

Parameters

type

The Type whose underlying type code to get.

Return Value

The TypeCode value of the underlying type.

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

    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;
        }
    } //WriteObjectInfo
} //Class1
