在IF ELSE中使用我的字符串

本文关键字：我的 字符串 IF ELSE | 更新日期: 2023-09-27 18:12:48

我是一个编程新手这是我第一次编程也是我第一次接触编程软件

首先让我给你看看我有什么:

private void SaveClose_Click(object sender, RoutedEventArgs e)
{
    using (var fs = new FileStream(@"Resources'arguments.txt", FileMode.Truncate))
    {
    }
    if (Windowed.IsChecked == true)
        windowed = true;
    else
        windowed = false;
    string text = File.ReadAllText(@"Resources'arguments.txt");
    string createTextWindowed = "-screen-fullscreen 0" + Environment.NewLine;
    File.WriteAllText(@"Resources'arguments.txt", createTextWindowed);
    string createTextFullscreen = "-screen-fullscreen 1" + Environment.NewLine;
    File.WriteAllText(@"Resources'arguments.txt", createTextFullscreen);

    if (windowed == true)
        createTextWindowed 
    else
        createTextFullscreen
}

第21行和第23行(createTextWindowed和createTextFullscreen)是错误的，我想修复它们，但我是一个新手，所以我不知道如何使用我所做的字符串，我想让程序写在txt文件"-screen-fullscreen 0"如果窗口=真(我想你得到了它)和1如果它是假的，我试过了，但当然它不起作用:')

在IF ELSE中使用我的字符串

  1. 你不需要这个，因为文件。WriteAllText将截断文件。

    using (var fs = new FileStream(@"Resources'arguments.txt", FileMode.Truncate))
{
}

  2. 也删除这个，因为它似乎没有使用它

    string text = File.ReadAllText(@"Resources'arguments.txt");

  3. 定义一个字符串变量，根据它是否有窗口来设置你想要写的文本。

    string textWrite;
if (windowed == true)
{
    textWrite = "-screen-fullscreen 0" + Environment.NewLine;
}
else
{
    textWrite = "-screen-fullscreen 1" + Environment.NewLine;
}

  4. 最后在文件

    中写入文本
    File.WriteAllText(@"Resources'arguments.txt", textWrite);

下面是函数修改后的完整代码:

private void SaveClose_Click(object sender, RoutedEventArgs e)
{
    if (Windowed.IsChecked == true)
        windowed = true;
    else
        windowed = false;
    string textWrite;
    if (windowed == true)
    {
        textWrite = "-screen-fullscreen 0" + Environment.NewLine;
    }
    else
    {
        textWrite = "-screen-fullscreen 1" + Environment.NewLine;
    }
    File.WriteAllText(@"Resources'arguments.txt", textWrite);
}

需要更改代码的逻辑顺序，因此:

    string text = File.ReadAllText(@"Resources'arguments.txt");
    if (Windowed.IsChecked)
    {
      text = text + "-screen-fullscreen 0" + Environment.NewLine;
    }
    else
    {
      text = text + "-screen-fullscreen 1" + Environment.NewLine;
    }
    File.WriteAllText(@"Resources'arguments.txt", text);

using指令是不必要的，所以你可以删除它。

如果windowed bool不在此范围之外使用，则没有必要，您可以使用windows。直接在if语句中检查。这使代码更加整洁。

然后你需要考虑代码的流程和逻辑。所以也许可以把它画在一张纸上，我的理解是:

  1. 从"Resources'arguments.txt"读取文本
  2. 如果Windowed.IsChecked为真，将参数-screen-fullscreen 0添加到文本
  3. 如果Windowed.IsChecked为假，则添加参数-screen-fullscreen 0到text
  4. 保存新文本到文件
也许你可以带着这些步骤回头看看你的原始代码，看看你是否能发现多余的代码。

你只需要稍微改变一下你的最终逻辑:

if (windowed == true)
{
    string createTextWindowed = "-screen-fullscreen 0" + Environment.NewLine;
    File.WriteAllText(@"Resources'arguments.txt", createTextWindowed);
}
else
{
    string createTextFullscreen = "-screen-fullscreen 1" + Environment.NewLine;
    File.WriteAllText(@"Resources'arguments.txt", createTextFullscreen);
}

然后在结尾放下

试试这个

private void SaveClose_Click(object sender, RoutedEventArgs e)
{
    string text = File.ReadAllText(@"Resources'arguments.txt");
    string createTextWindowed = "-screen-fullscreen 0" + Environment.NewLine;
    string createTextFullscreen = "-screen-fullscreen 1" + Environment.NewLine;
    if (Windowed.IsChecked == true)
    {
          File.WriteAllText(@"Resources'arguments.txt", createTextWindowed);
    }
    else
    {
          File.WriteAllText(@"Resources'arguments.txt", createTextFullscreen);
    }
}

        string createText;
        if (Windowed.IsChecked){
        createText= "-screen-fullscreen 0" + Environment.NewLine;        
        }
        else{
        createText = "-screen-fullscreen 1" + Environment.NewLine;        
    }
File.WriteAllText(@"Resources'arguments.txt", createText);
