ini配置文件的讀取

.ini 文件是Initialization File的縮寫，即初始化文件。是windows的系統配置文件所採用的存儲格式，統管windows的各項配置，通常用戶就用windows提供的各項圖形化管理界面就可實現相同的配置了，但在某些狀況，仍是要直接編輯.ini才方便，通常只有很熟悉windows才能去直接編輯。開始時用於WIN3X下面，WIN95用註冊表代替，以及後面的內容表示一個節，至關於註冊表中的鍵。

如今咱們的電腦裏面已經用註冊表來代替了ini文件的配置，可是咱們在一些程序裏面ini文件仍是沒法代替的

有一個setting.ini文件在運用程序.exe同目錄下

ini文件的格式

 

格式　　INI文件由節、鍵、值組成。

節

　　[section]

參數（鍵=值）

　　name=value

註解

　　註解使用分號表示（;）。在分號後面的文字，直到該行結尾都所有爲註解。

 

　　; comment textINI文件的數據格式的例子（配置文件的內容）　[Section1 Name]

 

　　KeyName1=value1

 

　　KeyName2=value2

 

　　...

 

　　[Section2 Name]

 

　　KeyName21=value21

 

　　KeyName22=value22

 

　　其中：

 

　　[Section1 Name]用來表示一個段落。

 

　　由於INI文件多是項目中共用的，因此使用[Section Name]段名來區分不一樣用途的參數區。例如：[Section1 Name]表示傳感器靈敏度參數區；[Section2 Name]表示測量通道參數區等等。

 

　　KeyName1=value1 用來表示一個參數名和值。

 

　　好比：

 

　　7033=50

 

　　7034=51

 

　　其中：

 

　　7033表示某傳感器名，50表示它的靈敏度值。

 

　　7034表示另外一隻傳感器名，51表示它的靈敏度值。

 

瞭解了ini的文件格式了，那麼如今就用一個類來操做它

cIni:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Text.RegularExpressions;
using System.Runtime.InteropServices;
namespace 你的命名空間
{
    class CIni
    {
        //聲明讀寫INI文件的API函數    
        public string path;
        public CIni()
        {
        }
        [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);
        /// <summary>
        /// ini文件編寫器
        /// </summary>
        /// <param name="section">查找ini文件的節點[]名</param>
        /// <param name="key">節點下邊的鍵</param>
        /// <param name="val">節點的值</param>
        /// <param name="filePath">來自的文件</param>
        public void WriterINI(string section, string key, string val,string filePath)
        {
            path = System.Environment.CurrentDirectory + "\\" + filePath;
            WritePrivateProfileString(section, key, val, path);
        }
        /// <summary>
        /// 讀取Ini文件
        /// </summary>
        /// <param name="section">得到節點</param>
        /// <param name="key">節點下邊的鍵</param>
        /// <param name="filePath">文件路徑</param>
        /// <returns>返回的值</returns>
        public string ReadINI(string section, string key, string filePath)
        {
            path = System.Environment.CurrentDirectory + "\\" + filePath;
            StringBuilder temp = new StringBuilder(255);
            GetPrivateProfileString(section, key, "", temp, 255, path);
            return temp.ToString().Trim();
        }
    }
}
用法：

 之前經常使用ini來作配置文件，如今打都是在用config 來做爲配置文件
