asp.net和SQL Server +事務回滾

Question

我下面有一部分函數，​​該函數從第一個SProc檢索一個autoID並將其作為參數傳遞給另一個SProc。 在這里，我使用事務回滾，比方說，我有一個先例，即第一個SProc成功執行了所有操作，但在第二個SProc中遇到了問題，第一個SProc操作是否會與第二個SProc一起回滾？ 一直以來，我只需要處理一項SProc交易，但這對我來說有點不同。 謝謝。

看來您正在使用2個存儲過程。 使用TransactionScope而不是DbTransaction，因此，這里可能是您的代碼

Using scope As New TransactionScope()
Try 
            If DbConnection.State <> ConnectionState.Open Then
