basic c# query

Im still kinda new to c# and there's something I cant quite get to grips with:

In VBA for example, if there is a bit of code I need throughout an app I would put it in a function then call it where ever I need it just by using the name of the function, eg

Sub Something()
    If variable = x then
        RunMyFunction
    end if
End Sub

Is there a similar way of calling re-usable code in c#? I do realise its a completely different beast to what Ive worked with before

thanks

If your function do not return value use void:

private void FunctionName ()
   {
      // Do something...
   }

If function return value than function have value type before function name:

private int FunctionNameReturnInt(int a, int b)
{     
   // Do something...
   int res = a + b;   
   return num;
}

...

// Calling functions
FunctionName();

int res;
res = FunctionNameReturnInt(1,2);

Yes, I sometimes create a new class called CommonFunctions.cs, and inside this class I would have the methods:

public class CommonFunctions
{
    public static void Something(int Variable)
    {
        if(Variable == 5)
            CommonFunctions.RunAnother();
    }
    public static void RunAnother()
    {

    }
}

Here is an example of a function:

public int AddNumbers(int number1, int number2)
{
    int result = number1 + number2;
    if(result > 10)
    {
        return result;
    }
}

The biggest departure you'll need to make from VBA is that C# is truly object-oriented. You'll have to get used to the idea of functions being a member of a class that you have to instantiate (in most cases).

Yes C# comes with functions as well. Sub is actually a function with void "return value".

So crude translation of your code to C# will be:

string RunMyFunction()
{
   return "hello";
}

void Something(variable, x)
{
   if (variable == x)
   {
      string value = RunMyFunction();
      //.....
   }
}

private void Something()
{
   if (variable == x)
   {
      RunMyFunction();
   }
}

private void RunMyFunction()
{
  // does something
}

In other words - it is basically the same. You define your resuable function as a method (RunMyFunction above) and then call it by name (with parenthesis).
