DefineNestedType Method (String, TypeAttributes, Type, Type[])

TypeBuilder.DefineNestedType Method (String, TypeAttributes, Type, Type[])

Defines a nested type, given its name, attributes, the type that it extends, and the interfaces that it implements.

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

[ComVisibleAttribute(true)]
public TypeBuilder DefineNestedType(
	string name,
	TypeAttributes attr,
	Type parent,
	Type[] interfaces
)

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.

interfaces
Type: System.Type[]

The interfaces that the nested type implements.

Return Value

Type: System.Reflection.Emit.TypeBuilder
The defined nested type.

ExceptionCondition
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.

-or-

An element of the interfaces array 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.
