MethodAttributes Enumeration

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)

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

Member nameDescription
Supported by the XNA FrameworkMemberAccessMaskRetrieves accessibility information.
Supported by the XNA FrameworkPrivateScopeIndicates that the member cannot be referenced.
Supported by the XNA FrameworkPrivateIndicates that the method is accessible only to the current class.
Supported by the XNA FrameworkFamANDAssemIndicates that the method is accessible to members of this type and its derived types that are in this assembly only.
Supported by the XNA FrameworkAssemblyIndicates that the method is accessible to any class of this assembly.
Supported by the XNA FrameworkFamilyIndicates that the method is accessible only to members of this class and its derived classes.
Supported by the XNA FrameworkFamORAssemIndicates that the method is accessible to derived classes anywhere, as well as to any class in the assembly.
Supported by the XNA FrameworkPublicIndicates that the method is accessible to any object for which this object is in scope.
Supported by the XNA FrameworkStaticIndicates that the method is defined on the type; otherwise, it is defined per instance.
Supported by the XNA FrameworkFinalIndicates that the method cannot be overridden.
Supported by the XNA FrameworkVirtualIndicates that the method is virtual.
Supported by the XNA FrameworkHideBySigIndicates that the method hides by name and signature; otherwise, by name only.
CheckAccessOnOverrideIndicates that the method can only be overridden when it is also accessible.
Supported by the XNA FrameworkVtableLayoutMaskRetrieves vtable attributes.
Supported by the XNA FrameworkReuseSlotIndicates that the method will reuse an existing slot in the vtable. This is the default behavior.
Supported by the XNA FrameworkNewSlotIndicates that the method always gets a new slot in the vtable.
Supported by the XNA FrameworkAbstractIndicates that the class does not provide an implementation of this method.
Supported by the XNA FrameworkSpecialNameIndicates that the method is special. The name describes how this method is special.
Supported by the XNA FrameworkPinvokeImplIndicates that the method implementation is forwarded through PInvoke (Platform Invocation Services).
Supported by the XNA FrameworkUnmanagedExportIndicates that the managed method is exported by thunk to unmanaged code.
Supported by the XNA FrameworkRTSpecialNameIndicates that the common language runtime checks the name encoding.
Supported by the XNA FrameworkReservedMaskIndicates a reserved flag for runtime use only.
Supported by the XNA FrameworkHasSecurityIndicates that the method has security associated with it. Reserved flag for runtime use only.
Supported by the XNA FrameworkRequireSecObjectIndicates that the method calls another method containing security code. Reserved flag for runtime use only.

The following example displays the attributes of the specified method.


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);
            }
        }
    }
}
