Default method parameter?

[RA]

Hi

What is c# default parameter passing for a method ? Is it ref?

Is this valid to change the object info in a method?

Class1
{
public string name;
int temp;
}
class test:
{
Main ()
{
class1 cs = new class1();

Update (cs);

//I should have here the following
//cs.name = "new name";
//cs.temp = 5;
}

void Update (Class1 cs)
{
cs.name = "new name";
cs.temp = 5;
}
}


Thanks,
Ronen

If you don't specify ref or out, it's passed by value.
