C#异步操作数据

  public async Task<bool> saveSizeDateData_One()
        {
            bool returnbool = false;
            var prdInt = 0;
            int sizeInt = 0;
            for (int i = roderNum; i < dgv_AssignSize.Rows.Count; i++)
            {
                var rs = await ActionSize(i);
                var  j = await savePPcPrd();
                sizeInt = sizeInt + rs;
                prdInt = prdInt + j;
            }
         return returnbool;
        }



  private async Task<int> ActionSize(int m)
        {
            string CreateDate = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");
            var i = 0;
            var rs = await Task.Run(async () =>
            {
                i = await saveSizeDateData_Two(m, CreateDate);
               
                return i;

            });
            return i;
        }


//saveSizeDateData_Two是对所有单个m的数据进行处理，就是确保操作个数一致
