如何修复错误 'Format of the initialization string does not conform to specification starting at index 100'

Question

这是我用于本地调试的连接字符串：

connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=SFP;
initial catalog=POLLINATORS;
integrated security=True;
MultipleActiveResultSets=True;
App=EntityFramework"

部分堆栈跟踪：

at System.Data.Entity.Core.EntityClient.Internal.DbConnectionOptions.GetKeyValuePair(String connectionString, Int32 currentPosition, StringBuilder buffer, String& keyname, String& keyvalue) at System.Data.Entity.Core.EntityClient.Internal.DbConnectionOptions.ParseInternal(IDictionary2 parsetable, String connectionString, IList1 validKeywords) at System.Data.Entity.Core.EntityClient.Internal.DbConnectionOptions。 .ctor(String connectionString, IList1 validKeywords) at System.Data.Entity.Core.EntityClient.EntityConnection.ChangeConnectionString(String newConnectionString) at System.Data.Entity.Core.EntityClient.EntityConnection..ctor(String connectionString) at System.Data.Entity.Internal.LazyInternalConnection.InitializeFromConnectionStringSetting(ConnectionStringSettings appConfigConnection) at System.Data.Entity.Internal.LazyInternalConnection.TryInitializeFromAppConfig(String name, AppConfig config) at System.Data.Entity.Internal.LazyInternalConnection.Initialize() at System.Data.Entity.Internal.LazyInternalConnection.CreateObjectContextFromConnectionModel() at System.Data.Entity.Internal.LazyInternalContext.InitializeContext() at System.Data.Entity.Internal.InternalContext.Initialize() at System.Data.Entity.Internal.InternalContext.GetEntitySetAndBaseTypeForType(Type entityType) at System.Data.Entity.Internal.Linq.InternalSet1.Initialize() 在 System.Data.Entity.Internal.Linq.InternalSet1.get_InternalContext() at System.Data.Entity.Infrastructure.DbQuery1.System.Linq.IQueryable.get_Provider()

您缺少提供商连接字符串中的结束引号：

connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=SFP;
initial catalog=POLLINATORS;
integrated security=True;
MultipleActiveResultSets=True;
App=EntityFramework""
