IDbConnectionInterceptor.ConnectionClosingAsync 方法

定义

在 EF 打算在异步上下文中调用 CloseAsync() 之前调用。

public System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> ConnectionClosingAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result);
public System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> ConnectionClosingAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result);
public virtual System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> ConnectionClosingAsync (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result);
abstract member ConnectionClosingAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult>
abstract member ConnectionClosingAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult>
abstract member ConnectionClosingAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult>
override this.ConnectionClosingAsync : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> System.Threading.Tasks.ValueTask<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult>
Public Function ConnectionClosingAsync (connection As DbConnection, eventData As ConnectionEventData, result As InterceptionResult) As Task(Of InterceptionResult)
Public Function ConnectionClosingAsync (connection As DbConnection, eventData As ConnectionEventData, result As InterceptionResult) As ValueTask(Of InterceptionResult)
Public Overridable Function ConnectionClosingAsync (connection As DbConnection, eventData As ConnectionEventData, result As InterceptionResult) As ValueTask(Of InterceptionResult)

参数

connection
DbConnection

连接。

eventData
ConnectionEventData

有关连接的上下文信息。

result
InterceptionResult

表示当前结果(如果存在)。 如果某个以前的侦听器通过调用 Suppress()来禁止执行,则此值已IsSuppressed设置为 true 。 此值通常用作此方法实现的返回值。

返回

如果 IsSuppressedfalse,则 EF 将照常继续。 如果 IsSuppressedtrue,则 EF 将取消它要执行的操作。 对于任何未尝试取消该操作的侦听器,此方法的实现是返回 result 传入的值。
