.NET框架中是否有可以读写标准.ini文件的类:
[Section]
<keyname>=<value>
...
Delphi有TIniFile组件,我想知道是否有类似的c# ?

如果你只是想要一个简单的阅读器没有部分和任何其他dll这里是一个简单的解决方案:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Tool
{
public class Config
{
Dictionary <string, string> values;
public Config (string path)
{
values = File.ReadLines(path)
.Where(line => (!String.IsNullOrWhiteSpace(line) && !line.StartsWith("#")))
.Select(line => line.Split(new char[] { '=' }, 2, 0))
.ToDictionary(parts => parts[0].Trim(), parts => parts.Length>1?parts[1].Trim():null);
}
public string Value (string name, string value=null)
{
if (values!=null && values.ContainsKey(name))
{
return values[name];
}
return value;
}
}
}
使用示例:
file = new Tool.Config (Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\config.ini");
command = file.Value ("command");
action = file.Value ("action");
string value;
//second parameter is default value if no key found with this name
value = file.Value("debug","true");
this.debug = (value.ToLower()=="true" || value== "1");
value = file.Value("plain", "false");
this.plain = (value.ToLower() == "true" || value == "1");
配置文件内容同时(如你所见,支持#符号的行注释):
#command to run
command = php
#default script
action = index.php
#debug mode
#debug = true
#plain text mode
#plain = false
#icon = favico.ico

我想介绍一个完全用c#创建的IniParser库,所以它不包含任何操作系统的依赖关系,这使得它与Mono兼容。MIT许可的开源软件——所以它可以在任何代码中使用。
你可以在GitHub中查看源代码,它也可以作为NuGet包使用
它是高度可配置的,使用起来非常简单。
很抱歉我不要脸的插播,但我希望它能对那些重新审视这个答案的人有所帮助。
如果您只需要读访问而不需要写访问,并且您正在使用microsoft . extensions . configuration(默认情况下与ASP. extension . configuration捆绑在一起)。你可以使用NuGet包Microsoft.Extensions.Configuration.Ini将ini文件导入到你的配置设置中。
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddIniFile("SomeConfig.ini", optional: false);
Configuration = builder.Build();
}
我迟到了,但我今天遇到了同样的问题,我写了下面的实现:
using System.Text.RegularExpressions;
static bool match(this string str, string pat, out Match m) =>
(m = Regex.Match(str, pat, RegexOptions.IgnoreCase)).Success;
static void Main()
{
Dictionary<string, Dictionary<string, string>> ini = new Dictionary<string, Dictionary<string, string>>();
string section = "";
foreach (string line in File.ReadAllLines(.........)) // read from file
{
string ln = (line.Contains('#') ? line.Remove(line.IndexOf('#')) : line).Trim();
if (ln.match(@"^[ \t]*\[(?<sec>[\w\-]+)\]", out Match m))
section = m.Groups["sec"].ToString();
else if (ln.match(@"^[ \t]*(?<prop>[\w\-]+)\=(?<val>.*)", out m))
{
if (!ini.ContainsKey(section))
ini[section] = new Dictionary<string, string>();
ini[section][m.Groups["prop"].ToString()] = m.Groups["val"].ToString();
}
}
// access the ini file as follows:
string content = ini["section"]["property"];
}
必须注意的是,这个实现不处理未找到的节或属性。 要实现这一点,您应该扩展Dictionary<,>-类来处理未找到的键。
要序列化Dictionary<string, Dictionary<string, string>>的实例到ini-file,我使用以下代码:
string targetpath = .........;
Dictionary<string, Dictionary<string, string>> ini = ........;
StringBuilder sb = new StringBuilder();
foreach (string section in ini.Keys)
{
sb.AppendLine($"[{section}]");
foreach (string property in ini[section].Keys)
sb.AppendLine($"{property}={ini[section][property]");
}
File.WriteAllText(targetpath, sb.ToString());
我发现了这个简单的实现:
http://bytes.com/topic/net/insights/797169-reading-parsing-ini-file-c
能满足我的需要。
下面是如何使用它:
public class TestParser
{
public static void Main()
{
IniParser parser = new IniParser(@"C:\test.ini");
String newMessage;
newMessage = parser.GetSetting("appsettings", "msgpart1");
newMessage += parser.GetSetting("appsettings", "msgpart2");
newMessage += parser.GetSetting("punctuation", "ex");
//Returns "Hello World!"
Console.WriteLine(newMessage);
Console.ReadLine();
}
}
代码如下:
using System;
using System.IO;
using System.Collections;
public class IniParser
{
private Hashtable keyPairs = new Hashtable();
private String iniFilePath;
private struct SectionPair
{
public String Section;
public String Key;
}
/// <summary>

String strLine = null;
String currentRoot = null;
String[] keyPair = null;
iniFilePath = iniPath;
if (File.Exists(iniPath))
{
try
{
iniFile = new StreamReader(iniPath);
strLine = iniFile.ReadLine();
while (strLine != null)
{
strLine = strLine.Trim().ToUpper();
if (strLine != "")
{
if (strLine.StartsWith("[") && strLine.EndsWith("]"))
{
currentRoot = strLine.Substring(1, strLine.Length - 2);
}
else
{
keyPair = strLine.Split(new char[] { '=' }, 2);
SectionPair sectionPair;
String value = null;

sectionPair.Section = currentRoot;
sectionPair.Key = keyPair[0];

试试这个方法:
public static Dictionary<string, string> ParseIniDataWithSections(string[] iniData)
{
var dict = new Dictionary<string, string>();
var rows = iniData.Where(t =>
!String.IsNullOrEmpty(t.Trim()) && !t.StartsWith(";") && (t.Contains('[') || t.Contains('=')));
if (rows == null || rows.Count() == 0) return dict;
string section = "";
foreach (string row in rows)
{
string rw = row.TrimStart();
if (rw.StartsWith("["))
section = rw.TrimStart('[').TrimEnd(']');
else
{
int index = rw.IndexOf('=');
dict[section + "-" + rw.Substring(0, index).Trim()] = rw.Substring(index+1).Trim().Trim('"');
}
}
return dict;
}
它创建键为“-”的字典。你可以这样加载它:
var dict = ParseIniDataWithSections(File.ReadAllLines(fileName));
