c# – 如何读取.net内核中的连接字符串?

导读:我想从配置文件只读一个连接字符串,因此 将一个名称为“AppAettings.json”的文件添加到我的项目中,并在其上添加此内容: {"ConnectionStrings": { "DefaultConnection": "Server=(localdb)mssqllocaldb;Database=aspnet- WebApplica71d622;Trusted_Connec
我想从配置文件只读一个连接字符串,因此
将一个名称为“AppAettings.json”的文件添加到我的项目中,并在其上添加此内容: { "ConnectionStrings": { "DefaultConnection": "Server=(localdb)mssqllocaldb;Database=aspnet- WebApplica71d622;Trusted_Connection=True;MultipleActiveResultSets=true" },"Logging": { "IncludeScopes": false,"LogLevel": { "Default": "Debug","System": "Information","Microsoft": "Information" } } } 在asp.net我用这个: var temp=ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString; 现在我如何读取c#中的“DefaultConnection”,并将其存储在.net核心中的字符串变量中? 解决方法
您可以使用GetConnectionString扩展方法:
string conString = Microsoft .Extensions .Configuration .ConfigurationExtensions .GetConnectionString(this.Configuration,"DefaultConnection"); System.Console.WriteLine(conString); 或使用DI的结构化类: public class SmtpConfig { public string Server { get; set; } public string User { get; set; } public string Pass { get; set; } public int Port { get; set; } } 启动: public IConfigurationRoot Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { // http://developer.telerik.com/featured/new-configuration-model-asp-net-core/ // services.Configure<SmtpConfig>(Configuration.GetSection("Smtp")); Microsoft.Extensions.DependencyInjection.OptionsConfigurationServiceCollectionExtensions.Configure<SmtpConfig>(services,Configuration.GetSection("Smtp")); 然后在家庭控制器中: public class HomeController : Controller { public SmtpConfig SmtpConfig { get; } public HomeController(Microsoft.Extensions.Options.IOptions<SmtpConfig> smtpConfig) { SmtpConfig = smtpConfig.Value; } //Action Controller public IActionResult Index() { System.Console.WriteLine(SmtpConfig); return View(); } 这在appsettings.json: "ConnectionStrings": { "DefaultConnection": "Server=(localdb)mssqllocaldb;Database=aspnet-WebApplica71d622;Trusted_Connection=True;MultipleActiveResultSets=true" },"Smtp": { "Server": "0.0.0.1","User": "user@company.com","Pass": "123456789","Port": "25" } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
