TypeCode Enumeration

Specifies the type of an object.

[Visual Basic]
<Serializable>
Public Enum TypeCode
[C#]
[Serializable]
public enum TypeCode
[C++]
[Serializable]
__value public enum TypeCode
[JScript]
public
   Serializable
enum TypeCode

Remarks

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.

Members

Member name Description
Boolean

Supported by the .NET Compact Framework.

A simple type representing Boolean values of true or false.
Byte

Supported by the .NET Compact Framework.

An integral type representing unsigned 8-bit integers with values between 0 and 255.

Example

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.
