工具:vs2019
winform中读取配置文件:appsettings.json
appsettings.json文件内容如下:
{ "ConnectionStrings": { "MySqlCon": "Data Source=localhost;Port=3306;Database=lgee_shop;User Id=root;Password=root;CharSet=utf8mb4;" } }
配置文件设置为:始终复制
读取步骤
第一步:引入相关包
1.Microsoft.Extensions.Configuration;
2.Microsoft.Extensions.Configuration.Json;
第二部:创建读取配置类文件
创建类文件:CustomConfigManager
using Microsoft.Extensions.Configuration; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace POSTrade { public class CustomConfigManager { //读取配置文件:appsettings //1.Microsoft.Extensions.Configuration; //2.Microsoft.Extensions.Configuration.Json; public static string GetConfig(string key) { var builder = new ConfigurationBuilder().AddJsonFile("appsettings.json"); //默认读取:当前运行目录 IConfigurationRoot configuration = builder.Build(); string configValue = configuration.GetSection(key).Value; return configValue; } } }
第三步:读取数据
//读取配置文件 string strCon = CustomConfigManager.GetConfig("ConnectionStrings:MySqlCon");
到此,配置文件的数据正常读取
