为什么我的方法在发生异常时没有回滚？
我在RunAfterTrans发生异常时使用环境事务：
我发现插入processMethod已成功完成，InsertTrans已成功完成！
public static int Insert(string processMethod, object[] processParameters, Type processType, object process, UserTransactionDTO transObj, string spPostConfirm, int toEmpNum)
{
int affectedRows = -7;
using (TransactionScope scope = new TransactionScope())
{
try
{
if (!string.IsNullOrEmpty(processMethod))
{
MethodInfo theMethod = processType.GetMethod(processMethod);
object res = theMethod.Invoke(process, processParameters);
transObj.ValuesKey = res.ToString();
}
affectedRows = InsertTrans(transObj);
if (affectedRows == 1)//Success
{
if (!string.IsNullOrEmpty(spPostConfirm))
{
affectedRows = RunPostConfirm(spPostConfirm, transObj.ValuesKey);
if (affectedRows == 0)
{
scope.Complete();//Commit
return 1;//Success
}
else
{
scope.Dispose();//Dispose
return -2;//Fail
}
}
else
{
affectedRows = RunAfterTrans(transObj.TaskCode, transObj.OldStatusCode, transObj, toEmpNum);
if (affectedRows == 1)
{
scope.Complete();//Commit
return 1;//Success
}
else
{
scope.Dispose();//Dispose
return -3;//Fail
}
}
}
else
{
scope.Dispose();//Dispose
return -1;//Fail
}
}
catch (Exception ee)
{
scope.Dispose();//Dispose
return -1;//Fail
}
}
}
Invoke调用的方法，例如：
public string InsertRequest(EnhancementRequest obj)
{
using (IfxConnection con = new IfxConnection(ConfigurationManager.ConnectionStrings["rsmj"].ToString()))
{
int affectedRow = -1;
int req_serial = 0;
req_serial = GetMaxSerial(DateTime.Now.Year);
StringBuilder cmdTxt = new StringBuilder();
cmdTxt.Append(" INSERT INTO hqmtbl(req_ser,req_year,req_date,emp_num,requirement_type,problem_def,reference,objective,main_code,year) VALUES (?,?,?,?,?,?,?,?,?,? ) ");
using (var myIfxCmd = new IfxCommand(cmdTxt.ToString(), con))
{
myIfxCmd.CommandType = CommandType.Text;
myIfxCmd.Parameters.Add("req_ser", IfxType.Integer);
myIfxCmd.Parameters.Add("req_year", IfxType.Integer);
myIfxCmd.Parameters.Add("req_date", IfxType.DateTime);
myIfxCmd.Parameters.Add("emp_num", IfxType.Integer);
myIfxCmd.Parameters.Add("requirement_type", IfxType.SmallInt);
myIfxCmd.Parameters.Add("problem_def", IfxType.LVarChar);
myIfxCmd.Parameters.Add("reference", IfxType.NVarChar);
myIfxCmd.Parameters.Add("objective", IfxType.LVarChar);
myIfxCmd.Parameters.Add("main_code", IfxType.Integer);
myIfxCmd.Parameters.Add("year", IfxType.Integer);
if (con.State == ConnectionState.Closed)
{
con.Open();
}
myIfxCmd.Parameters[0].Value = ((object)req_serial) ?? DBNull.Value;
myIfxCmd.Parameters[1].Value = DateTime.Now.Year;
myIfxCmd.Parameters[2].Value = ((object)obj.ReqDate) ?? DBNull.Value;
myIfxCmd.Parameters[3].Value = ((object)obj.EmpNum) ?? DBNull.Value;
myIfxCmd.Parameters[4].Value = ((object)obj.RequirementType) ?? DBNull.Value;
myIfxCmd.Parameters[5].Value = ((object)obj.ProblemDef) ?? DBNull.Value;
myIfxCmd.Parameters[6].Value = ((object)obj.Reference) ?? DBNull.Value;
myIfxCmd.Parameters[7].Value = ((object)obj.Objective) ?? DBNull.Value;
myIfxCmd.Parameters[8].Value = ((object)obj.MainCode) ?? DBNull.Value;
myIfxCmd.Parameters[9].Value = ((object)obj.Year) ?? DBNull.Value;
affectedRow = myIfxCmd.ExecuteNonQuery();
}
con.Close();
con.Dispose();
if (affectedRow > 0)
{
return DateTime.Now.Year + "," + req_serial;
}
else if (affectedRow == 0)
{
return string.Empty;
}
else
{
return affectedRow.ToString();
}
}
}
