从 .Net Core 中的 PackagemanagerConsole 获取错误同时运行更新数据库命令

Question

嗨，我在 .Net Core 应用程序中通过包管理器控制台编写更新数据库命令时出错。 我编写了 Update-Database，PMC 使用了 Update-Datebase。

PM> 更新-数据库

System.ArgumentException：不支持关键字：'datebase'。 在 Microsoft.Data.Common.DbConnectionOptions.ParseInternal(Dictionary 2 parsetable, String connectionString, Boolean buildChain, Dictionary 2同义词，Boolean firstKey) 在 Microsoft.Data.Common.DbConnectionOptions..ctor(String connectionString, Dictionary 2 synonyms) at Microsoft.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at Microsoft.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at Microsoft.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at Microsoft.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) at Microsoft.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at Microsoft.Data.SqlClient.SqlConnection..ctor(String connectionString) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerConnection.CreateDbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.get_DbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.Open(Boolean errorsExpected) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.<>c__DisplayClass18_0.<Exists>b__0(DateTime giveUp) at Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.<>c__DisplayClass12_0 2 synonyms) at Microsoft.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at Microsoft.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at Microsoft.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at Microsoft.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key) at Microsoft.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at Microsoft.Data.SqlClient.SqlConnection..ctor(String connectionString) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerConnection.CreateDbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.get_DbConnection() at Microsoft.EntityFrameworkCore.Storage.RelationalConnection.Open(Boolean errorsExpected) at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.<>c__DisplayClass18_0.<Exists>b__0(DateTime giveUp) at Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.<>c__DisplayClass12_0 2.b__0(DbContext c, TState s) 在 Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerExecutionStrategy.Execute[TState,TResult](TState state, Func 3 operation, Func 3 verifySucceeded) 在 Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.Execute[TState,TResult](IExecutionStrategy strategy, Func 2 operation, Func 2 verifySucceeded, TState state) 在 Microsoft.EntityFrameworkCore.ExecutionStrategyExtensions.Execute[TState,TResult](IExecutionStrategy strategy, TState state, Func`2 操作）在 Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.Exists(Boo 精益 retryOnNotExists) 在 Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerDatabaseCreator.Exists() 在 Microsoft.EntityFrameworkCore.Migrations.HistoryRepository.Exists() 在 Microsoft.EntityFrameworkCore.Migrations.Internal.Migrator.Migrate(String targetMigration) 在 Microsoft。 EntityFrameworkCore.Design.Internal.MigrationsOperations.UpdateDatabase(String targetMigration, String contextType) at Microsoft.EntityFrameworkCore.Design.OperationExecutor.UpdateDatabaseImpl(String targetMigration, String contextType) at Microsoft.EntityFrameworkCore.Design.OperationExecutor.UpdateDatabase.<>c__DisplayClass0_0.<. ctor>b__0() 在 Microsoft.EntityFrameworkCore.Design.OperationExecutor.OperationBase.Execute(Action action)

不支持的关键字：'datebase'。

这是因为在 Appsettings.json 中定义的连接字符串中有错字。 要在 .NetCore 中定义连接字符串，我们在 Appsettings.json "ConnectionStrings" 中写了以下行：{ "DefaultConnection": "Server=.;Database=BookListRazor;Trusted_Connection=True;MultipleActiveResultSets=True" }

而且我写错了强文本，所以EF不明白该怎么做。！
