Delphi有
文件组件,我想知道C#是否有类似的组件 .NET framework的创建者希望您使用基于XML的配置文件,而不是INI文件。因此,没有内置的机制来读取它们
不过,还有第三方解决方案可用
- INI处理程序可以通过以下方式获得,例如
- 您可以编写自己的INI处理程序,这是一种老式的、费劲的方法。它为您提供了对实现的更多控制,您可以将其用于好坏。见例
这篇关于CodeProject“”的文章应该会有所帮助
作者创建了一个C#类“Ini”,它公开了KERNEL32.dll中的两个函数。这些函数是:WritePrivateProfileString
和GetPrivateProfileString
。您需要两个名称空间:System.Runtime.InteropServices
和System.Text
使用Ini类的步骤
在项目命名空间定义中添加
using INI;
创建一个类似这样的文件
INIFile ini = new INIFile("C:\\test.ini");
使用ini写入值
将新值写入节中的特定键,或使用ini读取值
从特定节中的键读取值
注意:如果您是从头开始,您可以阅读这篇MSDN文章。这是配置应用程序的更好方法。中提供了Ini解析器
它有各种非常方便的重载来获取节/值,而且重量很轻。我发现了这个简单的实现:
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"];
}
很适合我的需要
以下是您如何使用它:
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();
}
}
