Type.GetMember Method (String, MemberTypes, BindingFlags)

Searches for the specified members of the specified member type, using the specified binding constraints.

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

public virtual MemberInfo[] GetMember (
	string name,
	MemberTypes type,
	BindingFlags bindingAttr
)
public MemberInfo[] GetMember (
	String name, 
	MemberTypes type, 
	BindingFlags bindingAttr
)
public function GetMember (
	name : String, 
	type : MemberTypes, 
	bindingAttr : BindingFlags
) : MemberInfo[]

Parameters

name

The String containing the name of the members to get.

type

The MemberTypes value to search for.

bindingAttr

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

-or-

Zero, to return an empty array.

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).

NotSupportedException

A derived class must provide an implementation.

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

This method searches the current classes and its base classes. 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 an empty array.

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 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, MemberTypes.Constructor for type, and BindingFlags.Static | BindingFlags.NonPublic (BindingFlags.StaticOrBindingFlags.NonPublic in Visual Basic) for bindingAttr. You can also get the class initializer using the TypeInitializer property.

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 methods of the myString class that start with the letter C.

    public void GetPublicInstanceMethodMemberInfo()
    {
        String myString = "GetMember_String_MemberType_BindingFlag";
        Type myType = myString.GetType();
        // Get the public instance methods for myString starting with the letter C.
        MemberInfo[] myMembers = myType.GetMember("C*", MemberTypes.Method, 
            BindingFlags.Public | BindingFlags.Instance);
        if(myMembers.Length > 0)
        {
            Console.WriteLine("\nThe public instance method(s) starting with the letter C for type {0}:", myType);
            for(int index=0; index < myMembers.Length; index++)
                Console.WriteLine("Member {0}: {1}", index + 1, myMembers[index].ToString());
        }
        else
            Console.WriteLine("No members match the search criteria.");    
    }
}

    public void GetPublicInstanceMethodMemberInfo()
    {
        String myString = "GetMember_String_MemberType_BindingFlag";
        Type myType = myString.GetType();
        // Get the public instance methods for myString starting with the
        // letter C.
        MemberInfo myMembers[] = myType.GetMember("C*", MemberTypes.Method,
            BindingFlags.Public | BindingFlags.Instance);
        if (myMembers.length > 0) {
            Console.WriteLine("\nThe public instance method(s) starting with"
                + " the letter C for type {0}:", myType);
            for (int index = 0; index < myMembers.length; index++) {
                Console.WriteLine("Member {0}: {1}", (Int32)(index + 1),
                    myMembers[index].ToString());
            }
        }
        else {
            Console.WriteLine("No members match the search criteria.");
        }
    } //GetPublicInstanceMethodMemberInfo
} //MyMemberSample
