call c# written dll functions through command line

Hello together,

i'm trying to call some functions wirtten in c# and compiled as a type
library (dll) trough the windows cmd shell. Is this generally possible?

My first idea was it to use rundll32.exe to call my user defined function,
but if i try to make a call like this: rundll32.exe mylib.dll,myFunc
Param1,Param2

The srouce code looks like this example
namespace test {
class TestClass {
public static myFunc(int param1, string param2){
/*SourceCode*/
return (ReturnData)
}
}
}

Is there Something special i have to consider?

regards
Roland
