MethodAttributes Enumeration

.NET Framework 4

Other Versions

Specifies flags for method attributes. These flags are defined in the corhdr.h file.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

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

Syntax

C++

Copy

[SerializableAttribute]
[FlagsAttribute]
[ComVisibleAttribute(true)]
public enum MethodAttributes

Members

	Member name	Description
	MemberAccessMask	Retrieves accessibility information.
	PrivateScope	Indicates that the member cannot be referenced.
	Private	Indicates that the method is accessible only to the current class.
	FamANDAssem	Indicates that the method is accessible to members of this type and its derived types that are in this assembly only.
	Assembly	Indicates that the method is accessible to any class of this assembly.
	Family	Indicates that the method is accessible only to members of this class and its derived classes.
	FamORAssem	Indicates that the method is accessible to derived classes anywhere, as well as to any class in the assembly.
	Public	Indicates that the method is accessible to any object for which this object is in scope.
	Static	Indicates that the method is defined on the type; otherwise, it is defined per instance.
	Final	Indicates that the method cannot be overridden.
	Virtual	Indicates that the method is virtual.
	HideBySig	Indicates that the method hides by name and signature; otherwise, by name only.
	CheckAccessOnOverride	Indicates that the method can only be overridden when it is also accessible.
	VtableLayoutMask	Retrieves vtable attributes.
	ReuseSlot	Indicates that the method will reuse an existing slot in the vtable. This is the default behavior.
	NewSlot	Indicates that the method always gets a new slot in the vtable.
	Abstract	Indicates that the class does not provide an implementation of this method.
	SpecialName	Indicates that the method is special. The name describes how this method is special.
	PinvokeImpl	Indicates that the method implementation is forwarded through PInvoke (Platform Invocation Services).
	UnmanagedExport	Indicates that the managed method is exported by thunk to unmanaged code.
	RTSpecialName	Indicates that the common language runtime checks the name encoding.
	ReservedMask	Indicates a reserved flag for runtime use only.
	HasSecurity	Indicates that the method has security associated with it. Reserved flag for runtime use only.
	RequireSecObject	Indicates that the method calls another method containing security code. Reserved flag for runtime use only.

Examples

The following example displays the attributes of the specified method.

C++

Copy


using System;
using System.Reflection;

class AttributesSample
{
    public void Mymethod (int int1m, out string str2m, ref string str3m)
    {
        str2m = "in Mymethod";
    }

    public static int Main(string[] args)
    {      
        Console.WriteLine ("Reflection.MethodBase.Attributes Sample");

        // Get the type of the chosen class.
        Type MyType = Type.GetType("AttributesSample");

        // Get the method Mymethod on the type.
        MethodBase Mymethodbase = MyType.GetMethod("Mymethod");

        // Display the method name and signature.
        Console.WriteLine("Mymethodbase = " + Mymethodbase);

        // Get the MethodAttribute enumerated value.
        MethodAttributes Myattributes = Mymethodbase.Attributes;

        // Display the flags that are set.
        PrintAttributes(typeof(System.Reflection.MethodAttributes), (int) Myattributes);
        return 0;
    }


    public static void PrintAttributes(Type attribType, int iAttribValue)
    {
        if (!attribType.IsEnum) {Console.WriteLine("This type is not an enum."); return;}

        FieldInfo[] fields = attribType.GetFields(BindingFlags.Public | BindingFlags.Static);
        for (int i = 0; i < fields.Length; i++)
        {
            int fieldvalue = (Int32)fields[i].GetValue(null);
            if ((fieldvalue & iAttribValue) == fieldvalue)
            {
                Console.WriteLine(fields[i].Name);
            }
        }
    }
}
