int day = 0;
//获得月份
String strMonth = comboBox2.SelectedItem.ToString().Split(new char[]{'月'},StringSplitOptions.RemoveEmptyEntries)[0];
String strYear = comboBox2.SelectedItem.ToString().Split(new char[]{'年'}, StringSplitOptions.RemoveEmptyEntries)[0];
//将月份转成整型，这里却报错，显示我上面那个月和年还没有分割出去，这怎么解决
int year = Convert.ToInt32(strYear);
int month = Convert.ToInt32(strMonth);
