How to change the value of a global variable in a function while there is a local variable of same name in C#

I want to change the global variable in a function where a local variable of same is already present.

int x=10;     //global variable
void fun1()
{
fun2(5);
}

void fun2(int x)
{
x=7;       //here i want that this statement assigns the value 7 to the global x
}

Just qualify it with this. It's a pretty common pattern, particularly for constructors:

public class Player
{
    private readonly string name;

    public Player(string name)
    {
        this.name = name;
    }
}

While I view it as acceptable if your parameter really is meant to be a new value for the field (potentially in a method which creates a new instance based on the current one and the new value for the single field, for example), I would try to avoid it in general, just from a readability perspective. Of course, the names of your private fields are an implementation detail, but when reading the code for the method, it's confusing to have two different concepts represented by the same variable name.
