在文本框中显示月份号 [英] Display month number in text box

问题描述

大家好，

我有一个服务开始日期并选择日期.用户将从日期时间选择器中选择日期.如果选择的日期大于服务开始日期，则它将显示月份号，例如，如果服务开始 date = 10/10/2011 并选择 date = 01/12/2011 ，则它将在文本框中显示2；如果选择 date = 9/9/2011 ，则将显示 -1 在文本框中.这是我的代码

Hi All,

I have a service commencement date and select date.Here user will select the date from date time picker.If selected date is greater than service comencement date then it will display the month number e.g if service commencement date =10/10/2011 and selected date=01/12/2011 then it will show 2 in textbox or if selected date=9/9/2011 then it will display -1 in textbox. Here is my code

DateTime dService= frmVwPersuit.dServiceCommDate;
           DateTime date = this.dateTimePicker1.Value;

           if (DateTime.Compare(dService, date) > 0)
           {
               this.txtMnth.Text = date.ToString("MM");
           }
           else
           {
               this.txtMnth.Text = date.ToString("-MM");
           }

推荐答案

int difference = date.Month - dService.Month;
this.txtMnth.Text = String.Format("{0:D2}", difference);

尝试一下..

try this..

DateTime dService= frmVwPersuit.dServiceCommDate;
            DateTime date = this.dateTimePicker1.Value;
 
            if (DateTime.Compare(dService, date) > 0)
            {
                this.txtMnth.Text = date.Month.ToString();
            }
            else
            {
                this.txtMnth.Text = date.Month.ToString();

            }

DateTime dService= frmVwPersuit.dServiceCommDate;
DateTime date = this.dateTimePicker1.Value;

this.txtMnth.Text = DateTime.Compare(dService, date) > 0 : date.Month.ToString() ? string.Format("-{0}",date.Month.ToString());

希望这会起作用.

谢谢
