嗨，我正在学习 C#，我有一些 .inf 文件（请参见下面的示例），我需要能够更改 [Destinations] 部分，其中一行以“00”或“0”开头并带有“+”。我曾尝试使用 Regex.Replace，但它会替换文件中包含“00”的所有条目。在这一点上，将两个条目都保留在文件中会很好但不是必需的。IE

[Destinations]
0="National",N,N
+="National",N,N
0024195="Gabon Mobiles",I,IMT
+24195="Gabon Mobiles",I,IMT

但现在只是更换将是一个巨大的帮助！再次感谢您对此提供的任何帮助。如果您有更多信息，请告诉我。

这是我对 C# 代码所做的。

private void button3_Click(object sender, EventArgs e)
{
   File.WriteAllText(txtnewtariff.Text, Regex.Replace(File.ReadAllText(txtcurrent.Text), "[00]", "+"));

更改您的正则表达式：

private void button3_Click(object sender, EventArgs e)
{
   File.WriteAllText(txtnewtariff.Text, Regex.Replace(File.ReadAllText(txtcurrent.Text), "^(0|00){1,2}", "+", RegexOptions.Multiline));
}

我认为这作为一个单一的正则表达式可能会很棘手。

我认为您最好只将替换应用到您要修改的部分：

var lines = File.ReadAllLines("path").ToList();
var regex = new Regex(@"^[0]{1,2}");
var startFrom = lines.IndexOf("[Destinations]");

//Start replacing from the index of "[Destinations]"
for (int i = startFrom; i < lines.Count; i++)
{
    //Assuming the ini section ends at an empty line - stop replacing
    if(lines[i].Trim() == string.Empty)
        break;

    lines[i] = regex.Replace(lines[i], "+");
}

File.WriteAllLines("path", lines);

我现在可以工作了，谢谢。
