如何从应用程序域中所有已加载的程序集中获取所有静态类，以及如何使用反射调用静态方法

Question

my requirement is as follows, is this possible ? if yes can someone please point me to any resources on this ?

1. get all the assemblies which end with the word "static" from an app domain
2. get hold of the static class which ends with the word "cache" from the assembly retrieved from step 1
3. Execute a static method named "invalidate" from the class retrieved from step 2

Answer 1

Try this:

foreach(Assembly asm in AppDomain.CurrentDomain.GetAssemblies())
{
    if (asm.GetName().Name.EndsWith("static"))
    {
        foreach(Type type in asm.GetTypes())
        {
            if (type.Name.EndsWith("cache"))
            {
                MethodInfo method = type.GetMethod("invalidate", BindingFlags.Static | BindingFlags.Public, null, Type.EmptyTypes, null);
                if (method != null)
                    method.Invoke(null, null);
            }
        }
    }
}

Or... if you prefer LINQ:

foreach(MethodInfo method in 
    AppDomain.CurrentDomain
    .GetAssemblies().Where(asm => asm.GetName().Name.EndsWith("static"))
    .SelectMany(asm => asm.GetTypes().Where(type => type.Name.EndsWith("cache"))
    .Select(type => type.GetMethod("invalidate", BindingFlags.Static | BindingFlags.Public, null, Type.EmptyTypes, null)).Where(method => method != null)))
        method.Invoke(null, null);
