推荐答案

尝试以下代码....

Hi,

Try the following Code....

DateTime dt1 = DateTime.Now.Date;
DateTime dt2 = dt1.Date.AddDays(-1* (dt1.Day - 1));

现在，您在 dt1 中获得当前日期，并在 dt2
中获得该月的第一个日期.
在日期控件中设置这些值.

干杯:)

Now you get Current Date in dt1 and also get first date of that month in dt2

Set those values in your date control.

Cheers :)

您可以像这样完成它:

You can get it done like this:

// format string to format the date like you need it
String formatString = "dd/MM/yyyy";
DateTime now = DateTime.Now;
DateTime date = new DateTime(now.Year, now.Month, 1); // create a date with current year and month and day 1
textBox1.Text = date.ToString(formatString);
textBox2.Text = now.ToString(formatString);

那应该为您做！
