Reflection and Attributes

[Jon Turner]

Given an object/class, how do I (using reflection) get a list of properties that have a specific attribute assigned to them ? In this example, I want to obtain a list of all propertiesthat have the attribute 'FooAttribute' assigned to them. Many TIA[AttributeUsage( AttributeTargets.Property)]public class FooAttribute:Attribute{ bool _isFooBarred; FooAttribute() { _isFooBarred = false;}}public class Foo{ [FooAttribute()] public byte Property1 { get{}; set{}; } [FooAttribute()] public int Property2 { get{}; set{}; } public string Property3 { get{}; set{}; }}

Here is one way to accomplish:

Type t = typeof (Foo);
MemberInfo[] mi = t.GetMembers(BindingFlags.GetProperty);
foreach (MemberInfo m in mi)
{
if (m.GetCustomAttributes(typeof(FooAttribute), false).Length > 0)
{
// FooAttribute defined for this property
}
}
