推荐答案

我只是将if子句中的count重置为1.

I would just reset count to 1 in the if clause.

if (month == 1)
               {
                   count=1;
                   DoId = (DateTime.Now.Year + cusId + ("00") + (count + 1) + "-DO").ToString();

               }
               else
               {
                   DoId = (DateTime.Now.Year + cusId + ("00") + (count + 1) + "-DO").ToString();

               }
