通過反射獲取所有繼承了某一接口的類

方法一：

 var types = AppDomain.CurrentDomain.GetAssemblies()
.SelectMany(a => a.GetTypes().Where(t => t.GetInterfaces().Contains(typeof(ISecurity))))
.ToArray();

 

方法二：

public static IEnumerable<Type> GetTypes(Type InterfaceType)
{
foreach (var assembly in AppDomain.CurrentDomain.GetAssemblies())
{
foreach (var type in assembly.GetTypes())
{
foreach (var t in type.GetInterfaces())
{
if (t == InterfaceType)
{
yield return type;
break;
}
}
}
}
}
