已过时.

异步执行命令,不产生任何结果。

ExecuteNonQueryAsync(RelationalCommandParameterObject, CancellationToken)

异步执行命令,不产生任何结果。

public System.Threading.Tasks.Task<int> ExecuteNonQueryAsync (Microsoft.EntityFrameworkCore.Storage.RelationalCommandParameterObject parameterObject, System.Threading.CancellationToken cancellationToken = default);
abstract member ExecuteNonQueryAsync : Microsoft.EntityFrameworkCore.Storage.RelationalCommandParameterObject * System.Threading.CancellationToken -> System.Threading.Tasks.Task<int>
Public Function ExecuteNonQueryAsync (parameterObject As RelationalCommandParameterObject, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Integer)

参数

parameterObject
RelationalCommandParameterObject

此方法的参数。

cancellationToken
CancellationToken

等待 CancellationToken 任务完成时要观察的 。

返回

表示异步操作的任务。 任务结果包含受影响的行数。

例外

适用于

ExecuteNonQueryAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, CancellationToken)

异步执行命令,不产生任何结果。

public System.Threading.Tasks.Task<int> ExecuteNonQueryAsync (Microsoft.EntityFrameworkCore.Storage.IRelationalConnection connection, System.Collections.Generic.IReadOnlyDictionary<string,object> parameterValues, System.Threading.CancellationToken cancellationToken = default);
abstract member ExecuteNonQueryAsync : Microsoft.EntityFrameworkCore.Storage.IRelationalConnection * System.Collections.Generic.IReadOnlyDictionary<string, obj> * System.Threading.CancellationToken -> System.Threading.Tasks.Task<int>
Public Function ExecuteNonQueryAsync (connection As IRelationalConnection, parameterValues As IReadOnlyDictionary(Of String, Object), Optional cancellationToken As CancellationToken = Nothing) As Task(Of Integer)

参数

connection
IRelationalConnection

要对其执行的连接。

parameterValues
IReadOnlyDictionary<String,Object>

参数的值。

cancellationToken
CancellationToken

等待 CancellationToken 任务完成时要观察的 。

返回

表示异步操作的任务。 任务结果包含受影响的行数。

适用于

ExecuteNonQueryAsync(IRelationalConnection, IReadOnlyDictionary<String,Object>, Boolean, CancellationToken)

注意

Use overload without 'manageConnection' parameter

异步执行命令,不产生任何结果。

public System.Threading.Tasks.Task<int> ExecuteNonQueryAsync (Microsoft.EntityFrameworkCore.Storage.IRelationalConnection connection, System.Collections.Generic.IReadOnlyDictionary<string,object> parameterValues = default, bool manageConnection = true, System.Threading.CancellationToken cancellationToken = default);
