方法“”没有重载，接受1个参数

Question

Well, my issue here is basically what it says in the title. I'm trying to call my bool value of my Player2 class for my Tic Tac Toe-project we have in school. I think it's worth mentioning that I use "Player Player1, Player2;" in the beginning of Form1.cs to create two instances of my class, Player. I've read multiple posts on the internet about this but all of them are people trying to call in more parameters than that they are providing. I don't see how a bool value of true or false is more than one.

Thanks in advance.

One of my buttons where this problem appears.

public void Btn1_Click(object sender, EventArgs e) >{

        {
            if (click1 == 0) 
            {
            if (Player2.GetActive(true))//(turn == 0)
                {
                 Btn1.Text = "X";
                }
                else
                {
                    >Btn1.Text = "O";
                }
                //turn++;
                click1++;
            }
            else
            {
                Btn1.Text = Btn1.Text;
           }
            display();
            checkit();
       }
    }

This is my player class.

` public class Player
{
    //Characteristics
    string name;
    int points;
    bool Active;

    //Constructor
    public Player() { points = 0; Active = true; }

    //Methods
    public void SetName(string n) { name = n; }
    public string GetName() { return name; }
    public void SetPoints(int p) { points = p; }
    public int GetPoints() { return points; }
    public void SetActive(bool a) { Active = a; }
    public bool GetActive() { return Active; }`

Answer 1

You have the code:

Player2.GetActive(true)

But you define get active as

public bool GetActive() { return Active; }`

So it is correct you have not defined a GetActive with a parameter.

Answer 2

Here,

if(Player2.GetActive(true))

you are passing an extra argument ( true ) to the method GetActive . As we can see from the method declaration of GetActive , it takes no parameters:

public bool GetActive() { return Active; }
//                   ↑
//              empty parentheses

I think what you mean here is "if Player2.GetActive() is true..." right? You don't need to specify the value you want if it is true , just doing this is fine:

if (Player2.GetActive())

If you want to check if it is false, add ! before the call to negate the result:

if (!Player2.GetActive())

Answer 3

Like BugFinder said, you are using the method to get the Active-Value instead of using the method to set the value.

So change

Player2.GetActive(true)

to

Player2.SetActive(true)

Just as an addition:
Since we are working with C# here and many of your methods are called set and get, I suggest you change those methods to be properties:

public string Name 
{
  get { return name; }
  set { name = value; }
}

public int Points 
{
  get { return points; }
  set { points = value; }
}

public bool Active 
{
  get { return active; }
  set { active = value; }
}

Now when you want to set the value, you can type

Player2.IsActive = true;

and to check the value simple type code like

If(Player2.IsActive)
  //Do Stuff
