IDbConnectionInterceptor.ConnectionClosing 方法

定义

在 EF 打算调用 之前调用 Close()

public Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult ConnectionClosing (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result);
public virtual Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult ConnectionClosing (System.Data.Common.DbConnection connection, Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result);
abstract member ConnectionClosing : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult
abstract member ConnectionClosing : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult
override this.ConnectionClosing : System.Data.Common.DbConnection * Microsoft.EntityFrameworkCore.Diagnostics.ConnectionEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult
Public Function ConnectionClosing (connection As DbConnection, eventData As ConnectionEventData, result As InterceptionResult) As InterceptionResult
Public Overridable Function ConnectionClosing (connection As DbConnection, eventData As ConnectionEventData, result As InterceptionResult) As 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,则此值将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 将禁止它要执行的操作。 对于任何不尝试取消该操作的侦听器,此方法的实现都是返回 result 传入的值。
