C# WPF 使用循环读取 INI 文件内容的示例

以下是使用 C# 循环读取 INI 文件的示例代码：

using System.Runtime.InteropServices;
using System.Text;

public class IniFile
{
    private string path;

    [DllImport("kernel32")]
    private static extern long WritePrivateProfileString(string section,
        string key, string val, string filePath);

    [DllImport("kernel32")]
    private static extern int GetPrivateProfileString(string section,
        string key, string def, StringBuilder retVal, int size, string filePath);

    public IniFile(string INIPath)
    {
        path = INIPath;
    }

    public void Write(string section, string key, string value)
    {
        WritePrivateProfileString(section, key, value, this.path);
    }

    public string Read(string section, string key)
    {
        StringBuilder temp = new StringBuilder(255);
        int i = GetPrivateProfileString(section, key, "", temp, 255, this.path);
        return temp.ToString();
    }

    public List<string> ReadSection(string section)
    {
        List<string> values = new List<string>();
        StringBuilder temp = new StringBuilder(255);
        int i = GetPrivateProfileString(section, null, "", temp, 255, this.path);
        string[] sections = temp.ToString().Split('�');
        foreach (string s in sections)
        {
            if (!string.IsNullOrEmpty(s))
            {
                values.Add(s);
            }
        }
        return values;
    }

    public Dictionary<string, string> ReadSectionValues(string section)
    {
        Dictionary<string, string> values = new Dictionary<string, string>();
        List<string> keys = ReadSection(section);
        foreach (string key in keys)
        {
            string value = Read(section, key);
            values.Add(key, value);
        }
        return values;
    }
}

//使用示例
IniFile ini = new IniFile("test.ini");

//写入数据
ini.Write("Section1", "Key1", "Value1");
ini.Write("Section1", "Key2", "Value2");
ini.Write("Section2", "Key3", "Value3");

//读取数据
string value1 = ini.Read("Section1", "Key1");
string value2 = ini.Read("Section1", "Key2");
string value3 = ini.Read("Section2", "Key3");

//循环读取Section1的所有键值对
Dictionary<string, string> section1Values = ini.ReadSectionValues("Section1");
foreach (KeyValuePair<string, string> kvp in section1Values)
{
    string key = kvp.Key;
    string value = kvp.Value;
}

本文示例代码展示了如何使用 C# 循环读取 INI 文件内容，并提供了写入、读取以及读取特定节的所有键值对等操作。代码示例简洁易懂，适合 WPF 开发者参考学习。
