Type.GetMember Method (String)

Searches for the public members with the specified name.

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

public:
virtual array<MemberInfo^>^ GetMember (
	String^ name
) sealed
public final MemberInfo[] GetMember (
	String name
)
public final function GetMember (
	name : String
) : MemberInfo[]

Parameters

name

The String containing the name of the public members to get.

Return Value

An array of MemberInfo objects representing the public members with the specified name, if found; otherwise, an empty array.

Exception typeCondition

ArgumentNullException

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

The search for name is case-sensitive. The search includes public static and public instance members.

Members include properties, methods, fields, events, and so on.

This method searches the current type and its base types. Only public methods can be found using this method. If the requested type is non-public and the caller does not have ReflectionPermission to reflect non-public objects outside the current assembly, this method returns a null reference (Nothing in Visual Basic).

This method overload will not find class initializers (.cctor). To find class initializers, use an overload that takes BindingFlags, and specify BindingFlags.Static | BindingFlags.NonPublic (BindingFlags.StaticOrBindingFlags.NonPublic in Visual Basic). You can also get the class initializer using the TypeInitializer property.

The following table shows what members of a base class are returned by the Get methods when reflecting on a type.

Member Type

Static

Non-Static

Constructor

No

No

Field

No

Yes. A field is always hide-by-name-and-signature.

Event

Not applicable

The common type system rule is that the inheritance is the same as that of the methods that implement the property. Reflection treats properties as hide-by-name-and-signature. See note 2 below.

Method

No

Yes. A method (both virtual and non-virtual) can be hide-by-name or hide-by-name-and-signature.

Nested Type

No

No

Property

Not applicable

The common type system rule is that the inheritance is the same as that of the methods that implement the property. Reflection treats properties as hide-by-name-and-signature. See note 2 below.

  1. Hide-by-name-and-signature considers all of the parts of the signature, including custom modifiers, return types, parameter types, sentinels, and unmanaged calling conventions. This is a binary comparison.

  2. For reflection, properties and events are hide-by-name-and-signature. If you have a property with both a get and a set accessor in the base class, but the derived class has only a get accessor, the derived class property hides the base class property, and you will not be able to access the setter on the base class.

  3. Custom attributes are not part of the common type system.

If the current T:System.Type represents a constructed generic type, this method returns the MemberInfo with the type parameters replaced by the appropriate type arguments.

If the current Type represents a type parameter in the definition of a generic type or generic method, this method searches the members of the class constraint, or the members of Object if there is no class constraint.

NoteNote

For generic methods, do not include the type arguments in name. For example, the C# code GetMember("MyMethod<int>") searches for a member with the text name "MyMethod<int>", rather than for a method named MyMethod that has one generic argument of type int.

The following example displays all the members of the String class that start with the letter C.
