C# 之 管理配置文件（二）

        通过上一篇博客《C# 之 管理配置文件（一）》给大家介绍了一下对我们传统的app.config或者web.config配置文件中配置变量的读取和写入，今天来给大家介绍一下对ini文件中配置变量的读取和写入。

        首先我们创建一个Test.ini的文件，其内容为：

[DateTime]
Value=2015/10/21 17:06:38

        编写读取和写入方法

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

namespace ConsoleApplication2
{
    public static class IniHelper
    {
        [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>
        /// 读取ini文件中节点的值
        /// </summary>
        /// <param name="Section">节</param>
        /// <param name="Key">键</param>
        /// <param name="FilePath">文件路径</param>
        /// <returns></returns>
        public static string IniReadValue(string Section, string Key, string FilePath)
        {
            StringBuilder temp = new StringBuilder(255);
            int i = GetPrivateProfileString(Section, Key, "", temp, 255, FilePath);

            return temp.ToString();

        }

        /// <summary>
        /// 往ini文件中节点写入值
        /// </summary>
        /// <param name="Section">节</param>
        /// <param name="Key">键</param>
        /// <param name="Value">值</param>
        /// <param name="filePath">文件路径</param>
        public static void IniWriteValue(string Section, string Key, string Value, string filePath)
        {
            WritePrivateProfileString(Section, Key, Value, filePath);
        }

        
    }
}

        调用我们的读取和写入方法

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            string strFilePath = "C:/Users/焱/Desktop/ConsoleApplication2/ConsoleApplication2/Test.ini";
            Console.WriteLine(IniHelper.IniReadValue("DateTime", "Value", strFilePath));

            IniHelper.IniWriteValue("DateTime", "Value", DateTime.Now.ToString(), strFilePath);

            Console.WriteLine(IniHelper.IniReadValue("DateTime", "Value", strFilePath));
        }
    }
}
