The default is to pass by value. If you want reference semantics, you can use the ref keyword.

Typically, the ref keyword (similar to the out keyword) is only used with value types (i.e. integer, double, float, etc.) For example:


// Pass a value type by value.
int i = 5;
Test(i);
Debug.WriteLine(i); // prints 5, because a copy is passed to the Test method

void Test(int param)
{
    param = 10;
}


// Pass a reference type by value.
string str = "hello";
Test(str);
Debug.WriteLine(str); // prints hello, because a copy of the reference to the "hello" string was passed to the Test method.

void Test(string param)
{
    param = "world";
}


// Pass a value type by reference
int i = 5;
Test(ref i);
Debug.WriteLine(ref i); // prints 10, because the reference to i was passed to the Test method

void Test(ref int param)
{
    param = 10;
}


// Pass a reference type by reference
string str = "hello";
Test(ref str);
Debug.WriteLine(str); // prints world, because the actual reference to str was passed to the Test method

void Test(ref string param)
{
   param = "world";
}
