passing function as argument in the function

how开发者_开发百科 to pass argument as function

You're probably looking for delegates.

public delegate void MyDelegate(int myInt, string myString);
public void FunctionToCall(int i, string s)
{
    Console.WriteLine(s + " [" + i.ToString() + "]");
}
public void MethodWithFunctionPointer(MyDelegate callback)
{
    callback(5, "The value is: ");
}

And then, to call it:

MethodWithFunctionPointer(FunctionToCall);

Make argument as delegate, and call function with address of function which should match with delegates
