TypeBuilder.DefineNestedType Method (String, TypeAttributes, Type, Int32)

 

Defines a nested type, given its name, attributes, the total size of the type, and the type that it extends.

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

Public Function DefineNestedType (
	name As String,
	attr As TypeAttributes,
	parent As Type,
	typeSize As Integer
) As TypeBuilder

Parameters

name
Type: System.String

The short name of the type. name cannot contain embedded nulls.

attr
Type: System.Reflection.TypeAttributes

The attributes of the type.

parent
Type: System.Type

The type that the nested type extends.

typeSize
Type: System.Int32

The total size of the type.

Return Value

Type: System.Reflection.Emit.TypeBuilder

The defined nested type.

Exception Condition
ArgumentException

The nested attribute is not specified.

-or-

This type is sealed.

-or-

This type is an array.

-or-

This type is an interface, but the nested type is not an interface.

-or-

The length of name is zero or greater than 1023.

-or-

This operation would create a type with a duplicate FullName in the current assembly.

ArgumentNullException

name is null.

This method can be used to create nested types even after the CreateType method has been called on the enclosing type.

The nested type needs to be complete before you can reflect on it using GetMembers, GetNestedType, or GetNestedTypes.

See the description of CreateType for the order in which nested types and nesting types should be completed.

A duplicate name is not necessarily created if name is identical to the name of a previously defined type or nested type. To be duplicates, the full names must be the same, including the namespace and all nesting types.
