c# - 在特定行之后读取行

Question

我正在尝试这样做，以便我可以读取“检查”之后出现的所有行，我尝试使用 StreamReader 或 clicli，而无法移动到下一行，同一行是经常阅读。

下面是一个提取的.txt文件示例，文件中有很多注册表项。

Windows Registry Editor Version 5.00

private void btnReplace_Click(object sender, EventArgs e)
{
     string check = "[HKEY_CURRENT_USER\SOFTWARE\Thingamahoochie\WinMerge\Settings-Bar1]";

     foreach (string line in File.ReadLines(_path))
     {
         if(line == check)
         {
            //need here read all line after "check"

         }
    }
}

您可以使用 bool 值来跟踪您是否在正确的位置:

这里我假设一个空行表示该部分的结尾。

bool readingTargetSection = false;
foreach (string line in File.ReadLines(_path))  
{
    if (readingTargetSection)
    {
        if (line.Trim() == "") {
            // or just break out of the loop
            readingTargetSection = false;
        }
        else {
            // read the line
        }
    }       
    else if (line == check)
    {
        readingTargetSection = true;
    }
}
