C#--使用json配置文件方法【可读写配置，适合小项目】（包含读取Json中文乱码解决方法）

1，添加jsconfig1.json配置文件

 2，编辑好json文件

 3，在bin目录中新建一个Config文件夹，把json文件复制过来

 

4，新建配置类

注意：类的属性名要跟json文件的可以名要保持一致

需要添加引用Newtonsoft.json

需要添加引用System.Windows.Forms

using System.IO;

using System.Text.RegularExpressions;

            //【注意】有中文会乱码
            //var jsonString = File.ReadAllText(Path.Combine(Application.StartupPath, "Config/app.json"));

            //【解决中文乱码方法】
            //eadAllText方法有:重载函数可以指定编码
            var jsonString = File.ReadAllText(Path.Combine(Application.StartupPath, "Config/app.json"), System.Text.Encoding.Default);
            _default = (ServerSettings)JsonConvert.DeserializeObject(jsonString, typeof(ServerSettings));

            get { return _barcodeFileName; }
            set { _barcodeFileName = value; }
        }

    }
}

　　

5，读取Json使用JSON：

            #region PLC 

            //初始化modbusmaster
            modbusFactory = new ModbusFactory();
            //在本地测试 所以使用回环地址,modbus协议规定端口号 502
            master = modbusFactory.CreateMaster(new TcpClient(ServerSettings.Default.SlaveIp,
                ServerSettings.Default.SlavePort));

            #endregion

　　

6，保存（写入Json）

        private void btn_saveProduct_BtnClick(object sender, EventArgs e)
        {
            FrmLogin frmLogin = new FrmLogin() { TopMost = true };
            DialogResult dialogResult2 = frmLogin.ShowDialog();
            if (dialogResult2 == DialogResult.OK)
            {
                ServerSettings.Default.IsAutoReceiveSop = chk_receive.Checked;
                ServerSettings.Save();
                MessageBox.Show("修改成功,重启软件后生效", "参数修改");
            }
            else { return; }

        }

7，特别注意：（中文逗号报错）
