Question
What is custom attribute? how to create? if i'm having custom attribute in an assembly, how to say that name in the code?
Answers
The primary steps to properly design custom attribute classes are as follows:
Applying the AttributeUsageAttribute
([AttributeUsage(AttributeTargets.All,
Inherited = false, AllowMultiple = true)])
Declaring the attribute. (class public class MyAttribute : System.Attribute { // .
. . })
Declaring constructors (public MyAttribute(bool myvalue) { this.myvalue =
myvalue; })
Declaring properties
public bool MyProperty
{
get {return this.myvalue;}
set {this.myvalue = value;}
}
The following example demonstrates the basic way of using reflection to get access to custom attributes.
class MainClass
{
public static void Main()
{
System.Reflection.MemberInfo info = typeof(MyClass);
object[] attributes = info.GetCustomAttributes();
for (int i = 0; i < attributes.Length; i ++)
{
System.Console.WriteLine(attributes[i]);
}
}
