• ini配置文件的读取


    .ini 文件是Initialization File的缩写,即初始化文件。是windows的系统配置文件所采用的存储格式,统管windows的各项配置,一般用户就用windows提供的各项图形化管理界面就可实现相同的配置了,但在某些情况,还是要直接编辑.ini才方便,一般只有很熟悉windows才能去直接编辑。开始时用于WIN3X下面,WIN95用注册表代替,以及后面的内容表示一个节,相当于注册表中的键。
    现在我们的电脑里面已经用注册表来代替了ini文件的配置,但是我们在一些程序里面ini文件还是无法代替的
    有一个setting.ini文件在运用程序.exe同目录下

    ini文件的格式
     
    格式  INI文件由节、键、值组成。

      [section]

    参数(键=值)

      name=value

    注解

      注解使用分号表示(;)。在分号后面的文字,直到该行结尾都全部为注解。
     
      ; comment textINI文件的数据格式的例子(配置文件的内容) [Section1 Name]
     
      KeyName1=value1
     
      KeyName2=value2
     
      ...
     
      [Section2 Name]
     
      KeyName21=value21
     
      KeyName22=value22
     
      其中:
     
      [Section1 Name]用来表示一个段落。
     
      因为INI文件可能是项目中共用的,所以使用[Section Name]段名来区分不同用途的参数区。例如:[Section1 Name]表示传感器灵敏度参数区;[Section2 Name]表示测量通道参数区等等。
     
      KeyName1=value1 用来表示一个参数名和值。
     
      比如:
     
      7033=50
     
      7034=51
     
      其中:
     
      7033表示某传感器名,50表示它的灵敏度值。
     
      7034表示另一只传感器名,51表示它的灵敏度值。
     
    了解了ini的文件格式了,那么现在就用一个类来操作它
    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 你的命名空间
    {
        class CIni
        {
            //声明读写INI文件的API函数    
            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文件编写器
            /// </summary>
            /// <param name="section">查找ini文件的节点[]名</param>
            /// <param name="key">节点下边的键</param>
            /// <param name="val">节点的值</param>
            /// <param name="filePath">来自的文件</param>
            public void WriterINI(string section, string key, string val,string filePath)
            {
                path = System.Environment.CurrentDirectory + "\" + filePath;
                WritePrivateProfileString(section, key, val, path);
            }
            /// <summary>
            /// 读取Ini文件
            /// </summary>
            /// <param name="section">获得节点</param>
            /// <param name="key">节点下边的键</param>
            /// <param name="filePath">文件路径</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:
        /// <summary>
            /// 读取Ini文件
            /// </summary>
            /// <param name="strConet">字段</param>

                CIni ini = new CIni();
                if (order == 1)

                else

                //你的方法写在这里.....          
            }
     以前常用ini来做配置文件,现在打都是在用config 来作为配置文件
