本文实例讲述了C#实现读写ini文件类。分享给大家供大家参考。具体如下：

这个C#类封装了对INI配置文件进行操作所需的各种函数，包括读取键值、读取键值、删除段落等

using System; using System.Runtime.InteropServices; using System.Text; namespace DotNet.Utilities { /// <summary> /// INI文件读写类。 /// </summary> public class INIFile { public string path; public INIFile(string INIPath) { path = INIPath; } [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); [DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string defVal, Byte[] retVal, int size, string filePath); /// <summary> /// 写INI文件 /// </summary> /// <param name="Section"></param> /// <param name="Key"></param> /// <param name="Value"></param> public void IniWriteValue(string Section,string Key,string Value) { WritePrivateProfileString(Section,Key,Value,this.path); } /// <summary> /// 读取INI文件 /// </summary> /// <param name="Section"></param> /// <param name="Key"></param> /// <returns></returns> public string IniReadValue(string Section,string Key) { StringBuilder temp = new StringBuilder(255); int i = GetPrivateProfileString(Section,Key,"",temp, 255, this.path); return temp.ToString(); } public byte[] IniReadValues(string section, string key) { byte[] temp = new byte[255]; int i = GetPrivateProfileString(section, key, "", temp, 255, this.path); return temp; } /// <summary> /// 删除ini文件下所有段落 /// </summary> public void ClearAllSection() { IniWriteValue(null,null,null); } /// <summary> /// 删除ini文件下personal段落下的所有键 /// </summary> /// <param name="Section"></param> public void ClearSection(string Section) { IniWriteValue(Section,null,null); } } }

希望本文所述对大家的C#程序设计有所帮助。
