以下这段代码只能读section下的第一行修改可以读取section的所有行using SystemRuntimeInteropServices;using SystemText;public class IniFile private string path; DllImportkernel32 private static extern long WritePrivatePr

修改后的代码：

using System.Runtime.InteropServices; using System.Text; using System.Collections.Generic;

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(32768);
    int i = GetPrivateProfileString(section, null, "", temp, 32768, this.path);
    string[] sections = temp.ToString().Split('\0');
    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; System.Console.WriteLine("Key: {0}, Value: {1}", key, value); }

//读取Section2的所有行 List section2Lines = ini.ReadSection("Section2"); foreach (string line in section2Lines) { System.Console.WriteLine(line);
