Type.GetMember Method (String, BindingFlags)

Searches for the specified members, using the specified binding constraints.

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

'Declaration
Public Overridable Function GetMember ( _
	name As String, _
	bindingAttr As BindingFlags _
) As MemberInfo()

Parameters

name
Type: System.String

The string containing the name of the members 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 an empty array.

Return Value

Type: System.Reflection.MemberInfo()
An array of MemberInfo objects representing the public members with the specified name, if found; otherwise, an empty array.

name is Nothing.

This method can be overridden by a derived class.

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

The GetMember method does not return members in a particular order, such as alphabetical or declaration order. Your code must not depend on the order in which members are returned, because that order varies.

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

  • You must specify either BindingFlags.Instance or BindingFlags.Static in order to get a return.

  • Specify BindingFlags.Public to include public members in the search.

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

  • Specify BindingFlags.FlattenHierarchy to include public and protected static members up the hierarchy; private static members in inherited classes are not included.

The following BindingFlags modifier flags can be used to change how the search works:

  • BindingFlags.IgnoreCase to ignore the case of name.

  • BindingFlags.DeclaredOnly to search only the members declared on the Type, not members that were simply inherited.

See System.Reflection.BindingFlags for more information.

To get the class initializer (.cctor) using this method overload, you must specify ".cctor" for name, and BindingFlags.Static | BindingFlags.NonPublic (BindingFlags.Static Or BindingFlags.NonPublic in Visual Basic) for bindingAttr. You can also get the class initializer using the TypeInitializer property.

If the current 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 public static members of the myString class that start with the letter C.

Public Sub GetPublicStaticMemberInfo()
    Dim myString As [String] = "GetMember_String_BindingFlag" 

    Dim myType As Type = myString.GetType()
    ' Get the public static members for the class myString starting with the letter C. 
    Dim myMembers As MemberInfo() = myType.GetMember("C*", BindingFlags.Public Or BindingFlags.Static)

    If myMembers.Length > 0 Then
        Console.WriteLine(ControlChars.Cr + "The public static member(s) starting with the letter C for type {0}:", myType)
        Dim index As Integer 
        For index = 0 To myMembers.Length - 1
            Console.WriteLine("Member {0}: {1}", index + 1, myMembers(index).ToString())
        Next index
    Else
        Console.WriteLine("No members match the search criteria.")
    End If 
End Sub 'GetPublicStaticMemberInfo
