读取 INI 文件 C# 的特定部分

Question

我有一个关于读取 ini 文件的问题， 我需要阅读我正在使用的ini文件的特定部分，但无法弄清楚如何做到这一点， 我已经可以读取和写入 ini 文件，但我需要读取特定部分。

这是我的 INI 文件：

[Settings]

[ACR]
11: Start Removal =90 // ms
12: Removal Time  =20 // commentary
13: Removal Delay =2.1 // commentary

[Cleaning]
21: Dur. Cleaning =90 //commentary
22: Time valve on =30  //commentary
23: Time valve off =15    //commentary

[Calibrate]
31: Content left =100//commentary
32: Calibrate left =--.-//commentary
33: Content right =100//commentary
34: Calibrate right =25.6//commentary

[Conductivity]
41: Factor left =500//commentary
42: Offset left =220//commentary
43: Factor right =500//commentary
44: Offset right =40//commentary
45: Level left =85//commentary
46: Level right =85//commentary

[General]
51: Type of valve =5//commentary
52: Indicator =2//commentary
53: Inverse output =0//commentary
54: Restart time =30//commentary
55: Water time =0//commentary
56: Gate delay =10//commentary

[Pulsation]
61: Pulsation p/m =60//commentary
62: S/r ratio front =55//commentary
63: S/r ratio back =60//commentary
64: Stimulation p/m =200//commentary
65: S/r stim front =30//commentary
66: S/r stim back =30//commentary
67: Stimulation dur =20//commentary

我必须阅读该行的前 2 个字符，所以在 ACR 部分下我需要阅读 10、11 和 12。在清理部分时，我必须阅读 21、22、23 等等。

这是我目前的代码：

using System;

        public Settings LoadSettings(bool defaults = false)
        {
            String fileName = defaults ? FileNameDefault : FileNameCustom;
            StringList input = new StringList().FromFile(fileName);

            //Settings settings = null;
            Settings settings = new Settings();

            foreach (var item in input)
            {
                String line = item.Trim();

                if (line.StartsWith("[") && line.EndsWith("]"))
                    continue;

                int index = line.IndexOf('=');
                if (index < 0)
                    continue;

                String key = line.Substring(0, index).Trim();

                String value = line.Substring(index + 1).Trim();
                String comment = "";
                index = value.IndexOf("//");
                if (index > -1)
                {
                    comment = value.Substring(index).Trim();
                    value = value.Substring(0, index).Trim();
                }

提前致谢，我知道我没有正确使用 INI 文件，但这是最简单的方法。

Awnser 感谢 Neoistheone 的帮助

      foreach (var item in input)
                    {
                        String line = item.Trim();

                        if (line.StartsWith("[") && line.EndsWith("]"))
                            continue;

                        int index = line.IndexOf('=');
                        if (index < 0)
                            continue;

                        String key = line.Substring(0, index).Trim();
                        String ID = line.Substring(0, line.IndexOf(':'));
                        String value = line.Substring(index + 1).Trim();
                        //String comment = "";

                            //comment = value.Substring(index).Trim();
                            value = value.Substring(0, index).Trim();
                        }



                        // ACR
                        if (Utils.EqualsIgnoreCase(key, "11: Start Removal"))

                           }

返回设置； }

我知道我没有正确使用 INI 文件，但这是最简单的 方式。

我认为这不是最简单的方法，尝试一些已经实现的方法： GetPrivateProfileSection.

有 2 个有用的 windows API 来读取/写入 ini 文件：

GetPrivateProfileString

WriteProfileString

检查一下！

您可以使用读取 INI 文件的第三方类：

http://www.codeproject.com/Articles/1966/An-INI-file-handling-class-using-C

Answer 3

这将为您完成：

var vals = File.ReadLines("C:\\TEMP\\test.ini")
    .SkipWhile(line => !line.StartsWith("[ACR]"))
    .Skip(1)
    .TakeWhile(line => !string.IsNullOrEmpty(line))
    .Select(line => new
    {
        Key = line.Substring(0, line.IndexOf(':')),
        Value = line.Substring(line.IndexOf(':') + 2)
    });

解释

• .SkipWhile(line => !line.StartsWith("[ACR]")) 会一直跳到它找到它想要的部分。
• .Skip(1) 跳过该行，因为我们真的想读取值。
• .TakeWhile(line => !string.IsNullOrEmpty(line)) 一直读取直到找到一个空行。
• .Select(line => new... 将每一行的值选择为匿名类型。

因此，只需传入正确的部分即可获得所需的任何部分。

这种方法的另一个好处是它可以延迟执行，因此如果您不必阅读整个文件即可找到它不会找到的部分。

现在，在您的情况下，您可能需要稍微调整一下，以确保它不会读取行尾的 cmets，例如更改最后一个 Substring。这实际上取决于真正的域需求，但这不会是一个大的修改。

您当然也可以修改它以满足您需要的任何其他类型的查询的需要。

Answer 4

正如其他人所说，有比伪 INI 文件更好的方法来保存您的设置，但如果必须，您可以使用正则表达式来解析您的字符串：

void Main()
{

    string line1 = "[ACR]";
    string line2 = "53: Inverse output =0.3//commentary";

    var a = Regex.Match(line1,@"^\[(.*)\]").Groups;
    var b = Regex.Match(line2,@"^(\d\d):\s*(.*)\s*=(.*)//(.*)").Groups;

    string sectionName = a[1].Value;

    string number = b[1].Value;
    string setting = b[2].Value;
    string value = b[3].Value;
    string comment = b[4].Value;

}
