i tried the above code which works only once in the loop

推荐答案

试试这个

try this

for (int i = 0; i < dt.Rows.Count; i++)
          {
              string date = dt.Rows[i]["Month"].ToString();
              string[] date1 = date.Split('/');
              string month = date1[0];
              string year = date1[2];
              //from date
              string getmonth = txtfromdate.Text.Trim();
              string[] words = getmonth.Split('/');
              string newmonth = words[0].ToString();

              //todate
              string getyear = txtToDate.Text.Trim();
              string[] words1 = getyear.Split('/');
              string newyear = words1[2].ToString();


              if (month == newmonth && year == newyear)
              {
                  txtfromdate.Text = newmonth.ToString();
                  txtToDate.Text = newyear.ToString();
                  Ismatch = true;
                  break;
              }
              else
              {
                  Ismatch = false;

              }
          }
