Public Overridable Function ExecuteNonQueryAsync (connection As IRelationalConnection, Optional parameterValues As IReadOnlyDictionary(Of String, Object) = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Integer)

參數

connection
IRelationalConnection

要對其執行的連線。

parameterValues
IReadOnlyDictionary<String,Object>

參數的值,如果命令沒有參數,則 null 為 。

cancellationToken
CancellationToken

等候 CancellationToken 工作完成時要觀察的 。

傳回

代表非同步作業的工作。 工作結果包含受影響的資料列數目。
