entity framework – 索引0处的初始化字符串的格式
这是例外，
System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0. at System.Data.Common.DbConnectionOptions.GetKeyValuePair(String connectionString, Int32 currentPosition, StringBuilder buffer, Boolean useOdbcRules, String& keyname, String& keyvalue) at System.Data.Common.DbConnectionOptions.ParseInternal(Hashtable parsetable, String connectionString, Boolean buildChain, Hashtable synonyms, Boolean firstKey) at System.Data.Common.DbConnectionOptions..ctor(String connectionString, Hashtable synonyms, Boolean useOdbcRules) at System.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at System.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) at System.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at System.Data.Entity.Internal.LazyInternalConnection.Initialize() at System.Data.Entity.Internal.LazyInternalConnection.get_Connection() at System.Data.Entity.Infrastructure.DbContextInfo..ctor(Type contextType, DbProviderInfo modelProviderInfo, AppConfig config, DbConnectionInfo connectionInfo) at System.Data.Entity.Infrastructure.DbContextInfo..ctor(Type contextType, DbConnectionInfo connectionInfo) at System.Data.Entity.Migrations.DbMigrator..ctor(DbMigrationsConfiguration configuration, DbContext usersContext) at System.Data.Entity.MigrateDatabaseToLatestVersion`2.InitializeDatabase(TContext context) at System.Data.Entity.Internal.InternalContext.PerformInitializationAction(Action action) at System.Data.Entity.Internal.InternalContext.PerformDatabaseInitialization() at System.Data.Entity.Internal.RetryAction`1.PerformAction(TInput input) at System.Data.Entity.Internal.LazyInternalContext.InitializeDatabaseAction(Action`1 action) at System.Data.Entity.Internal.InternalContext.GetEntitySetAndBaseTypeForType(Type entityType) at System.Data.Entity.Internal.Linq.InternalSet`1.Initialize() at System.Data.Entity.Internal.Linq.InternalSet`1.get_InternalContext() at System.Data.Entity.Infrastructure.DbQuery`1.System.Linq.IQueryable.get_Provider() at System.Linq.Queryable.OrderByDescending[TSource,TKey](IQueryable`1 source, Expression`1 keySelector) at Article.GetAll() in Article.cs:line 43 at ASP._Page_Views_Home_Index_cshtml.Execute() in Index.cshtml:line 9 at System.Web.WebPages.WebPageBase.ExecutePageHierarchy() at System.Web.Mvc.WebViewPage.ExecutePageHierarchy() at System.Web.WebPages.StartPage.ExecutePageHierarchy() at System.Web.WebPages.WebPageBase.ExecutePageHierarchy(WebPageContext pageContext, TextWriter writer, WebPageRenderingBase startPage) at System.Web.Mvc.ViewResultBase.ExecuteResult(ControllerContext context) at System.Web.Mvc.ControllerActionInvoker.c__DisplayClass1a.b__17() at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter(IResultFilter filter, ResultExecutingContext preContext, Func`1 continuation) at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter(IResultFilter filter, ResultExecutingContext preContext, Func`1 continuation) at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter(IResultFilter filter, ResultExecutingContext preContext, Func`1 continuation) at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultWithFilters(ControllerContext controllerContext, IList`1 filters, ActionResult actionResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.c__DisplayClass25.b__22(IAsyncResult asyncResult) 我的连接字符串是，
<add name="MyContext" connectionString="Persist Security Info=false;Integrated Security=false;Connection Timeout=4;Initial Catalog=;User ID=;pwd=;server=" providerName="System.Data.SqlClient"/> <parameter value="Data Source=;Initial Catalog=Master;Persist Security Info=False;User ID=;Password=;MultipleActiveResultSets=True;Application Name=EntityFramework" />
我不知道是怎么回事。 我的连接字符串不工作怎么样？
!!更新！
有趣的是 – 我发现当我使用Web部署时，会添加一个新的连接字符串和entity framework>默认连接工厂>参数……我知道对不对？ 什么？！
我发布的“生产就绪”web.config的结果如下所示：
<add name="MyContext" connectionString="Data Source=;Initial Catalog=;Persist Security Info=False;User ID=;Password=; MultipleActiveResultSets=True;Application Name=EntityFramework" providerName="System.Data.SqlClient" /> <add name="MyContext_DatabasePublish" connectionString="Data Source=;Initial Catalog=;Persist Security Info=False;User ID=;Password=; MultipleActiveResultSets=True;Application Name=EntityFramework" providerName="System.Data.SqlClient" /> <databaseInitializer type="System.Data.Entity.MigrateDatabaseToLatestVersion`2[[MyContextDBContext, Models], [Models.Migrations.Configuration, MyWebsite.Models]], EntityFramework, PublicKeyToken=">
很有意思吧？
现在，当发布时，网站会抛出“连接字符串错误的格式”。
我想我想要的是删除自动添加新连接字符串和上下文的需要，并且正是我在web配置中放置的内容。
最糟糕的是，这个所谓的“function”打破了web.config转换的使用。 事实上，我开始喜欢使用新的“预览变换”function。 但是，即使预览确实显示了这些变化。
这里发生了什么？
我可以删除吗？
如果将其添加到Global.asax，您应该知道字符串有什么问题。
throw new Exception(ConfigurationManager.ConnectionStrings["MyContext"].ConnectionString);
如果您看到任何令牌占位符，您应该更好地了解该做什么。
还要检查用户的SQL服务器权限。
我遵循了所有建议，没有任何效果。 但我发现这行创建了错误：Database.EnsureCreated（）
删除EnsureCreated方法后，我能够创建第一次迁移。
