MemberInfo.GetCustomAttributes Method (Boolean)

When overridden in a derived class, returns an array containing all the custom attributes.

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

public abstract Object[] GetCustomAttributes (
	bool inherit
)
public abstract Object[] GetCustomAttributes (
	boolean inherit
)
public abstract function GetCustomAttributes (
	inherit : boolean
) : Object[]

Parameters

inherit

Specifies whether to search this member's inheritance chain to find the attributes.

Return Value

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

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.
[AttributeUsage(AttributeTargets.All)]

        {
            return myName;
