Type.GetNestedType Method (String, BindingFlags)

When overridden in a derived class, searches for the specified nested type, using the specified binding constraints.

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

abstract GetNestedType : 
        name:string * 
        bindingAttr:BindingFlags -> Type

Parameters

name
Type: System.String

The string containing the name of the nested type to get.

bindingAttr
Type: System.Reflection.BindingFlags

A bitmask comprised of one or more BindingFlags that specify how the search is conducted.

-or-

Zero, to return a null reference (Nothing in Visual Basic).

Return Value

Type: System.Type
An object representing the nested type that matches the specified requirements, if found; otherwise, a null reference (Nothing in Visual Basic).

Implements

_Type.GetNestedType(String, BindingFlags)

ExceptionCondition
ArgumentNullException

name is a null reference (Nothing in Visual Basic).

Use the simple name of the nested class for name. Do not qualify it with the name of the outer class. For a generic nested class, use the mangled name — that is, append a grave accent and the number of generic parameters. For example, use the string "Inner`1" to get the generic nested class Inner<T> (Inner(Of T) in Visual Basic). Do not include language-specific syntax for type parameters.

The following BindingFlags filter flags can be used to define which nested types to include in the search:

  • You must specify either BindingFlags.Public or BindingFlags.NonPublic to get a return.

  • Specify BindingFlags.Public to include public nested types in the search.

  • Specify BindingFlags.NonPublic to include non-public nested types (that is, private, internal, and protected nested types) in the search.

This method returns only the nested types of the current type. It does not search the base classes of the current type. To find types that are nested in base classes, you must walk the inheritance hierarchy, calling GetNestedType at each level.

BindingFlags.Instance and BindingFlags.Static are ignored.

Calling this method with only the BindingFlags.Public flag or only the BindingFlags.NonPublic flag will return the specified nested types and does not require any other flags.

See System.Reflection.BindingFlags for more information.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the nested types of the class constraint.

If a nested type is generic, this method returns its generic type definition. This is true even if the enclosing generic type is a closed constructed type.

NoteNote

If the current Type represents a generic type defined in C#, Visual Basic, or C++, its nested types are all generic even if they have no generic parameters of their own. This is not necessarily true of nested types defined in dynamic assemblies or compiled with the Ilasm.exe (IL Assembler).

For information on nested generic types, and on constructing nested generic types from their generic type definitions, see MakeGenericType.
