DbCommandInterceptor.NonQueryExecutedAsync 方法
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
在 EF 调用 后立即调用 ExecuteNonQueryAsync()。
如果侦听器禁止在 中 NonQueryExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Int32>, CancellationToken)执行命令,则仍会调用此方法。
在本例中, result
是 返回 NonQueryExecutingAsync(DbCommand, CommandEventData, InterceptionResult<Int32>, CancellationToken)的结果。
public virtual System.Threading.Tasks.Task<int> NonQueryExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, int result, System.Threading.CancellationToken cancellationToken = default);
public virtual System.Threading.Tasks.ValueTask<int> NonQueryExecutedAsync (System.Data.Common.DbCommand command, Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData eventData, int result, System.Threading.CancellationToken cancellationToken = default);
abstract member NonQueryExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<int>
override this.NonQueryExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<int>
abstract member NonQueryExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * int * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<int>
override this.NonQueryExecutedAsync : System.Data.Common.DbCommand * Microsoft.EntityFrameworkCore.Diagnostics.CommandExecutedEventData * int * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<int>
Public Overridable Function NonQueryExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As Integer, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Integer)
Public Overridable Function NonQueryExecutedAsync (command As DbCommand, eventData As CommandExecutedEventData, result As Integer, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Integer)
参数
- command
- DbCommand
命令。
- eventData
- CommandExecutedEventData
有关命令和执行的上下文信息。
- result
- Int32
调用 ExecuteNonQueryAsync()的结果。 此值通常用作此方法实现的返回值。
- cancellationToken
- CancellationToken
等待 CancellationToken 任务完成时要观察的 。
返回
提供 Task EF 将使用的结果的 。
对于不尝试更改结果的任何侦听器,此方法的正常实现是返回 result
传入的值,通常使用 FromResult<TResult>(TResult)
