invoke non static method in c# -


i want invoke class "***" solution works me want invoke solution gives me error :

type t = type.gettype(svclass); methodinfo method = t.getmethod("execute", bindingflags.instance| bindingflags.public);  ret = (string)method.invoke(null, new object[] { context.request});     public string execute(httprequest req) 

so tried methodinfo method = t.getmethod("execute", bindingflags.instance | bindingflags.public);

but gives me error "non-static method requires target"

*** working solution static method

type t = type.gettype(svclass); methodinfo method = t.getmethod("execute", bindingflags.static| bindingflags.public);  ret = (string)method.invoke(null, new object[] { context.request}); 

to invoke

public class xxxxx     {         public static string execute(httprequest req){}     } 

the secret change binding flags methodinfo matches signature of method wish call.

eg:

 public static string execute(httprequest req){} 

will accessed via

methodinfo method = t.getmethod("execute", bindingflags.static| bindingflags.public); 

however, access

public string execute(httprequest req){} 

you need

var classobj = new class(); methodinfo method = classobj.gettype().getmethod("execute", bindingflags.instance| bindingflags.public); 

instance means method member of class object, , not of class type. (instance vs static)

var parameterarray = new object[]{ yourhttprequesthere}; var result = method.invoke(classobj,parameterarray); 

so remember, if method belongs instance, need grab method instance type, , need invoke reference instance variable (classobj) above.
