How to access a function of a namespace from outside of application in c#? -

i have namespace shown below.

 namespace testnamespace     {         public class testclass : system.web.ui.page         {             public static string testdata;               public void test()             {                 string s = "fgdfgdg";              }             protected string invoke(string methodname)             {                 //string methodname = "test";                 string classname = methodname.split('-')[0];                  string funcname=methodname.split('-')[1];                  type type = type.gettype(classname);                  activator.createinstance(type);                  methodinfo method = type.getmethod(funcname);               string result = (string)method.invoke(activator.createinstance(type), null);              return result;             }             public static string testfunc(string temp)             {                 hdndata = temp;                           string strval=  invoke(s);                return strval;              }         }     } 

i referencing dll in application given below.

using testnamespace;  protected void button1_click(object sender, eventargs e)         {            string test='testfunction';             string s=testfunc(test);         } 

when declare function public im getting error

"an object reference required non-static field, method, or property "

but when declare public static can access function other functions,variables needs declared static. i dont want functions of class static function testfunc. how can this?

to call static function should specify class name first. otherwise compiler not know, method call. in example replace:

string s=testfunc(test); 

with

string s = testclass.testfunc(test); 

you should provide valid parameters, matching method's signature, when calling method.invoke(...), otherwise runtime exception.

and while dont know, why 1 create such design (and dont explain idea behind test class either), looks "bad" design me.
