C# Windows形成不同的类，试图更改textbox.text

我试图创建一个函数，从我的设置文件（HighscoreSaved wich被放入highscoreList数组）中获取数据，然后连接字符串并将其写入文本框（highScore.Text）

但是，当我调用函数时，什么都没有发生

这是我的代码： 表格1

下面是Highscore.Fetch（）和Highscore.Set（）应该调用的类 但是当我打电话给他们时，我的文本框里没有任何变化

public static class Highscore
    {
        public static void  Fetch()
        {
            Form1.highscoreList[0] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper1 + "\t\t" + HighscoreSaved.Default.highscoreScore1;
            Form1.highscoreList[1] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper2 + "\t\t" + HighscoreSaved.Default.highscoreScore2;
            Form1.highscoreList[2] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper3 + "\t\t" + HighscoreSaved.Default.highscoreScore3;
            Form1.highscoreList[3] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper4 + "\t\t" + HighscoreSaved.Default.highscoreScore4;
            Form1.highscoreList[4] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper5 + "\t\t" + HighscoreSaved.Default.highscoreScore5;
            Form1.highscoreList[5] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper6 + "\t\t" + HighscoreSaved.Default.highscoreScore6;
            Form1.highscoreList[6] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper7 + "\t\t" + HighscoreSaved.Default.highscoreScore7;
            Form1.highscoreList[7] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper8 + "\t\t" + HighscoreSaved.Default.highscoreScore8;
            Form1.highscoreList[8] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper9 + "\t\t" + HighscoreSaved.Default.highscoreScore9;
            Form1.highscoreList[9] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper10 + "\t\t" + HighscoreSaved.Default.highscoreScore10;

            Form1.highscoreInt[0] = HighscoreSaved.Default.highscoreScore1;
            Form1.highscoreInt[1] = HighscoreSaved.Default.highscoreScore2;
            Form1.highscoreInt[2] = HighscoreSaved.Default.highscoreScore3;
            Form1.highscoreInt[3] = HighscoreSaved.Default.highscoreScore4;
            Form1.highscoreInt[4] = HighscoreSaved.Default.highscoreScore5;
            Form1.highscoreInt[5] = HighscoreSaved.Default.highscoreScore6;
            Form1.highscoreInt[6] = HighscoreSaved.Default.highscoreScore7;
            Form1.highscoreInt[7] = HighscoreSaved.Default.highscoreScore8;
            Form1.highscoreInt[8] = HighscoreSaved.Default.highscoreScore9;
            Form1.highscoreInt[9] = HighscoreSaved.Default.highscoreScore10;

            Form1.highscoreKeeper[0] = HighscoreSaved.Default.highscoreKeeper1;
            Form1.highscoreKeeper[1] = HighscoreSaved.Default.highscoreKeeper2;
            Form1.highscoreKeeper[2] = HighscoreSaved.Default.highscoreKeeper3;
            Form1.highscoreKeeper[3] = HighscoreSaved.Default.highscoreKeeper4;
            Form1.highscoreKeeper[4] = HighscoreSaved.Default.highscoreKeeper5;
            Form1.highscoreKeeper[5] = HighscoreSaved.Default.highscoreKeeper6;
            Form1.highscoreKeeper[6] = HighscoreSaved.Default.highscoreKeeper7;
            Form1.highscoreKeeper[7] = HighscoreSaved.Default.highscoreKeeper8;
            Form1.highscoreKeeper[8] = HighscoreSaved.Default.highscoreKeeper9;
            Form1.highscoreKeeper[9] = HighscoreSaved.Default.highscoreKeeper10;                
        }
        public static void Set()
        {
            Form1 mainForm = new Form1();
            string[] highscoreImported = new string[10];
            Array.Copy(Form1.highscoreList, highscoreImported, 10);
            string highscores = string.Join("\n", highscoreImported);
            mainForm.highscoreText(highscores);
        }

您正在

Set

方法中创建

Form1

的新实例，这就是您没有看到更改的原因。您应该将表单的一个实例传递给该方法

比如（在你的班级中，

Highscore

）：

以后您可以这样称呼它：

private void button4_Click_1(object sender, EventArgs e)
{
    Highscore.Fetch();
    Highscore.Set(this); //notice "this"
}

更好的方法是一次完成所有任务

using System.Linq;

public static void  FetchAndSet()
{
    Form1.highscoreList[0] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper1;
    .
    .

    Form1.highscoreInt[0] = HighscoreSaved.Default.highscoreScore1;
    .
    .

    Form1.highscoreKeeper[0] = HighscoreSaved.Default.highscoreKeeper1;
    .
    .

    //Use LINQ's Take to Pull out the Top 10.   
    string highscores = string.Join("\n", highscoreList.Take(10));
    this.highscoreText(highscores);     
}

private void button4_Click_1(object sender, EventArgs e)
{
    Highscore.Fetch();
    Highscore.Set(this); //notice "this"
}

using System.Linq;

public static void  FetchAndSet()
{
    Form1.highscoreList[0] = "\t\t\t" + HighscoreSaved.Default.highscoreKeeper1;
    .
    .

    Form1.highscoreInt[0] = HighscoreSaved.Default.highscoreScore1;
    .
    .

    Form1.highscoreKeeper[0] = HighscoreSaved.Default.highscoreKeeper1;
    .
    .

    //Use LINQ's Take to Pull out the Top 10.   
    string highscores = string.Join("\n", highscoreList.Take(10));
    this.highscoreText(highscores);     
}
