MemberInfo.GetCustomAttributes Method (Boolean)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

When overridden in a derived class, returns an array of all custom attributes applied to this member.

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

public abstract object[] GetCustomAttributes(
	bool inherit


Type: System.Boolean

true to search this member's inheritance chain to find the attributes; otherwise, false. This parameter is ignored for properties and events; see Remarks.

Return Value

Type: System.Object[]

An array that contains all the custom attributes applied to this member, or an array with zero elements if no attributes are defined.

Exception Condition

This member belongs to a type that is loaded into the reflection-only context. See How to: Load Assemblies into the Reflection-Only Context.


A custom attribute type could not be loaded.

This method ignores the inherit parameter for properties and events. To search the inheritance chain for attributes on properties and events, use the appropriate overloads of the Attribute.GetCustomAttributes method.


   In the .NET Framework version 2.0, this method returns security attributes on methods, constructors, and types if they are stored in the new metadata format. Assemblies compiled with version 2.0 use this format. Dynamic assemblies and assemblies compiled with earlier versions of the .NET Framework use the old XML format. See Emitting Declarative Security Attributes.

The following example defines a custom attribute and associates the attribute with MyClass.MyMethod, retrieves the attribute at run time, and displays the result.

using System;
using System.Reflection;

// Define a custom attribute with one named parameter.
public class MyAttribute : Attribute
    private string myName;
    public MyAttribute(string name)
        myName = name;
    public string Name
            return myName;

// Define a class that has the custom attribute associated with one of its members.
public class MyClass1
    [MyAttribute("This is an example attribute.")]
    public void MyMethod(int i)

public class MemberInfo_GetCustomAttributes
    public static void Main()
            // Get the type of MyClass1.
            Type myType = typeof(MyClass1);
            // Get the members associated with MyClass1.
            MemberInfo[] myMembers = myType.GetMembers();

            // Display the attributes for each of the members of MyClass1.
            for(int i = 0; i < myMembers.Length; i++)
                Object[] myAttributes = myMembers[i].GetCustomAttributes(true);
                if(myAttributes.Length > 0)
                    Console.WriteLine("\nThe attributes for the member {0} are: \n", myMembers[i]);
                    for(int j = 0; j < myAttributes.Length; j++)
                        Console.WriteLine("The type of the attribute is {0}.", myAttributes[j]);
        catch(Exception e)
            Console.WriteLine("An exception occurred: {0}", e.Message);
