我查看了System.Data.SqlClient.SqlTransaction中的Dispose()方法(使用反编译器):

 protected override void Dispose(bool disposing)
    {
      if (disposing)
      {
        SNIHandle target = (SNIHandle) null;
        RuntimeHelpers.PrepareConstrainedRegions();
        try
        {
          target = SqlInternalConnection.GetBestEffortCleanupTarget(this._connection);
          if (!this.IsZombied)
          {
            if (!this.IsYukonPartialZombie)
              this._internalTransaction.Dispose();
          }
        }
        catch (OutOfMemoryException ex)
        {
          this._connection.Abort((Exception) ex);
          throw;
        }
        catch (StackOverflowException ex)
        {
          this._connection.Abort((Exception) ex);
          throw;
        }
        catch (ThreadAbortException ex)
        {
          this._connection.Abort((Exception) ex);
          SqlInternalConnection.BestEffortCleanup(target);
          throw;
        }
      }
      base.Dispose(disposing);
    }

为什么每个人都在论坛中说它正在回滚处置?它在哪里回滚?

答案 0 :(得分:4)

@BlorgBeard是正确的说“我相信内部事务回滚在它自己的Dispose中 - 即在this._internalTransaction.Dispose();”。把它写成其他人的答案。 (见最后声明)

System.Data.SqlClient.SqlInternalTransaction.Dispose()的代码 - 查看最后一行:

private void Dispose(bool disposing)
{
  Bid.PoolerTrace("<sc.SqlInteralTransaction.Dispose|RES|CPOOL> %d#, Disposing\n", this.ObjectID);
  if (!disposing || this._innerConnection == null)
    return;
  this._disposing = true;
  this.Rollback();
}
