所有内置的.Net属性

Question

我使用AppDomain.CurrentDomain.GetAssemblies()列出了所有程序集，但是如何使用C＃列出.NET 2.0中的所有内置属性？

Answer 1

Note that AppDomain.GetAssemblies() will only list the loaded assemblies... but then it's easy:

var attributes = from assembly in assemblies
                 from type in assembly.GetTypes()
                 where typeof(Attribute).IsAssignableFrom(type)
                 select type;

.NET 2.0 (non-LINQ) version:

List<Type> attributes = new List<Type>();
foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
{
    foreach (Type type in assembly.GetTypes())
    {
        if (typeof(Attribute).IsAssignableFrom(type))
        {
            attributes.Add(type);
        }
    }                   
}
