ASP.NET MVC Find class by class attribute value using Reflection

Mark Devid 2284 14 Aug 2014

I have a class with a custom attribute that has a string parameter.

[ANAttribute("Ampe21")]
public class ClassB : ClassA
{
}

I have different action names defined for different classes.

What I want is to obtain the namespace of ClassB or obtain the type of ClassB by searching the entire application after Ampe21.

How can I do that?

Hi Mark,

Try this:


var types = AppDomain.CurrentDomain.GetAssemblies()
    .SelectMany(x =>x.GetTypes()
        .Where(t =>t.GetCustomAttribute<ANAttribute>() != null &&                   
t.GetCustomAttribute<ANAttribute>().YourProperty =="Ampe21")
    );
foreach (var type in types)
{
   
Console.WriteLine(type.Namespace);
}
