本文實例講述了C#實現讀寫ini文件類。分享給大家供大家參考。具體如下：
這個C#類封裝了對INI配置文件進行操作所需的各種函數，包括讀取鍵值、讀取鍵值、刪除段落等
using System;using System.Runtime.InteropServices;using System.Text;namespace DotNet.Utilities{ /// <summary> /// INI文件讀寫類。 /// </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> /// 寫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> /// 讀取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> /// 刪除ini文件下所有段落 /// </summary> public void ClearAllSection() { IniWriteValue(null,null,null); } /// <summary> /// 刪除ini文件下personal段落下的所有鍵 /// </summary> /// <param name="Section"></param> public void ClearSection(string Section) { IniWriteValue(Section,null,null); } }}希望本文所述對大家的C#程序設計有所幫助。
