Question

我的代码出现问题。我的代码应该（我想要它做的）是在游戏结束后出现一个spritefont，允许你输入文本，一旦输入该文本，它就会将该分数写入文本文件。但当然不会这样做。如果有人能提供帮助，那就太棒了。

修改这是我在游戏结束后尝试输入文字的方法（游戏是太空入侵者）也许这里也有问题。

SpriteFont Label;
string txt = ".";
Keys PrevKey;
string[] HighScores = new string[5];
int count = 0;

KeyboardState ks = Keyboard.GetState();
Keys[] k = ks.GetPressedKeys();
Keys tempKey = Keys.None;
string keyChar = "";

foreach (Keys q in k)
{
    Keys currentKey = q;

    if (ks.IsKeyUp(PrevKey))
    {
        if (!(q == Keys.None))
        {
            switch (q)
            {
                case Keys.Space: keyChar = " "; break;
                case Keys.Delete: txt = ""; break;
                case Keys.Back: txt = txt.Remove(txt.Length - 1); break;
                case Keys.Enter: HighScores[count] = txt; count++; txt = "";
                                 if (count == 5) count = 0; break;
                case Keys.End: WriteScores(); break;
                case Keys.Home: ReadScores(); break;
                default: keyChar = q.ToString(); break;
            }
            txt += keyChar;
        }
    }

    if (currentKey != Keys.None && ks.IsKeyDown(currentKey))
    {
        tempKey = currentKey;
    }
}

PrevKey = tempKey;
base.Update(gameTime);
}
}
}
}

public void WriteScores()
{
    StreamWriter Rite = new StreamWriter(@"C:\TheScores.txt");      
    for (int i = 0; i < HighScores.Length; i++)
    {
        Rite.WriteLine(HighScores[i]);
    }  
    Rite.Close();
}

public void ReadScores()
{
    if (File.Exists(@"C:\TheHighScores.txt"))
    {
        StreamReader Reed = new StreamReader(@"C:\TheScores.txt");
        for (int i = 0; i < HighScores.Length; i++)
        {
            txt += Reed.ReadLine() + "\n";
        }
        Reed.Close();
    }
}

将路径更改为Documents或AppData等用户文件夹。您的代码将因为权限不足而抛出访问冲突，除非您以管理员身份运行程序，因为C：\的根目录只能在提升的上下文中使用。
