读写ini文件

读写ini文件需要引入系统接口 

 

//首先，引入命名空间
using System.Runtime.InteropServices;

在修改系统接口：

        string path=@"d:config.ini";//带路径的文件名

       [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>
        /// 创建ini文件
        /// </summary>
        /// <param name="Section">ini文件的标题</param>
        /// <param name="Key">键</param>
        /// <param name="Value">键值</param>
        private void IniWriteValue(string Section, string Key, string Value)
        ...{
            WritePrivateProfileString(Section, Key, Value, this.path);
        }
        /**//// <summary>
        /// 读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();

        }

 

示例：

 

private void btnCreateIni_Click(object sender, EventArgs e)
        ...{
            string[] configIniKeys = new string[6]...{
                                                "企业代码",
                                                "服务代码",
                                                "登陆账号",
                                                "登陆密码",
                                                "IP",
                                                "端口"};
            string[] configIniValues = new string[6]...{
                                                "1001",
                                                "13826128578",
                                                "chenrong",
                                                "1234",
                                                "10.244.14.138",
                                                "8080"};

            if (!File.Exists(path))
            ...{
                using (FileStream fs = File.Create(path))
                ...{
                    fs.Close();
                }
            }
            try
            ...{
                for (int i = 0; i < configIniKeys.Length; i++)
                ...{
                    IniWriteValue("短信网关配置信息", configIniKeys[i], configIniValues[i]);
                }
                MessageBox.Show("ini文件生成成功！", "成功");
            }
            catch (Exception ex)
            ...{
                MessageBox.Show(ex.ToString());
            }
        }

生成的ini文件如下：

[短信网关配置信息]
企业代码=1001
服务代码=13826128578
登陆账号=chenrong
登陆密码=1234
IP=10.244.14.138
端口=8080
