ASP.NET创建Web服务之使用事务

' This command should execute properly.
deleteCmd.Connection.Open()
deleteCmd.ExecuteNonQuery()

' This command results in an exception, so the first command is
' automatically rolled back. Since the XML Web service method is
' participating in a transaction, and an exception occurs, ASP.NET
' automatically aborts the transaction. The deleteCmd that
' executed properly is rolled back.

Dim cmdResult As Integer = exceptionCausingCmd.ExecuteNonQuery()
sqlConn.Close()

Return cmdResult
End Function
End Class
