CodeTypeDeclaration Class

Represents a type declaration for a class, structure, interface, or enumeration.

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

[SerializableAttribute]
[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)]
[ComVisibleAttribute(true)]
public class CodeTypeDeclaration : CodeTypeMember

CodeTypeDeclaration can be used to represent code that declares a class, structure, interface, or enumeration. CodeTypeDeclaration can be used to declare a type that is nested within another type.

The BaseTypes property specifies the base type or base types of the type being declared. The Members property contains the type members, which can include methods, fields, properties, comments and other types. The TypeAttributes property indicates the TypeAttributes values for the type declaration, which indicate the type category of the type. The IsClass, IsStruct, IsEnum, and IsInterface methods indicate whether the type is a class, structure, enumeration, or interface type, respectively.

NoteNote:

Some programming languages only support the declaration of reference types, or classes. To check a language-specific CodeDOM code generator for support for declaring interfaces, enumerations, or value types, call the Supports method to test for the appropriate GeneratorSupport flags. DeclareInterfaces indicates support for interfaces, DeclareEnums indicates support for enumerations, and DeclareValueTypes indicates support for value types such as structures.

You can build a class or a structure implementation in one complete declaration, or spread the implementation across multiple declarations. The IsPartial property indicates whether the type declaration is complete or partial. Not all code generators support partial type declarations, so you should test for this support by calling the Supports method with the flag PartialTypes.

This example demonstrates using a CodeTypeDeclaration to declare a type.

// Creates a new type declaration.
CodeTypeDeclaration newType = new CodeTypeDeclaration(
    // name parameter indicates the name of the type. 
    "TestType");
// Sets the member attributes for the type to private.
newType.Attributes = MemberAttributes.Private;
// Sets a base class which the type inherits from.
newType.BaseTypes.Add( "BaseType" );            

// A C# code generator produces the following source code for the preceeding example code: 

// class TestType : BaseType 
// { 
// }

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
