MethodBase.Attributes Property

Gets the attributes associated with this method.

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

public abstract MethodAttributes Attributes { get; }
/** @property */
public abstract MethodAttributes get_Attributes ()

public abstract function get Attributes () : MethodAttributes

Not applicable.

Property Value

One of the MethodAttributes values.

All members have a set of attributes, which are defined in relation to the specific type of member.

To get the MethodAttributes, first get the type. From the type, get the method. From the method, get the MethodAttributes.

Notes to Implementers: Use the Attributes property to determine whether a method is public, private, final, virtual, and so on.

The following code example displays the attributes of the user-defined method Mymethod.

using System.Reflection;
 
class AttributesSample
{
    public void Mymethod (int int1m, out string str2m, ref string str3m)
    {

    }

        // Get the type.
        Type MyType = Type.GetType("AttributesSample");
 
        // Get the method Mymethod on the type.
        MethodBase Mymethodbase = MyType.GetMethod("Mymethod");
 
        // Display the method name.
        Console.WriteLine("Mymethodbase = " + Mymethodbase);
 
        // Get the MethodAttribute enumerated value.
        MethodAttributes Myattributes = Mymethodbase.Attributes;
 
        // Display the flags that are set.
