1、写入数据库连接字符串
比如:
"ConnectionStrings": { "Conn": "Data Source=.;Initial Catalog=TestDome;Integrated Security=True" }
2、新建 AppsettingJson.cs 类
例如:
public class AppSettingsJson { public static IConfiguration Configuration { get; set; } static AppSettingsJson() { //ReloadOnChange = true 当appsettings.json被修改时重新加载 Configuration = new ConfigurationBuilder() .Add(new JsonConfigurationSource { Path = "appsettings.json", ReloadOnChange = true }) .Build(); } }
3、选择变量接受数据库连接字符串
例如:
var ConnectionString = AppSettingsJson.Configuration.GetConnectionString("Conn");
4、此时的ConnectionString中已经包含了有关于Conn中所定义的字符串。
