推荐答案

获取ID的前六个字符的子字符串:

Take a Substring of the first six characters of the ID:

9910231234567 --->> 991023

现在在DateTimePicker.Value上使用ToString:

Now use ToString on the DateTimePicker.Value:

string s = dateTimePicker1.Value.ToString("yyMMdd");

并比较两个字符串.

And compare the two strings.

以下功能可能对您有用.

Hi,

below function may be useful for you.

bool compareID(DateTime selectedDate,double ID)
{
return selectedDate.ToString("yyMMdd") == ID.ToString().SubString(0,6) : true? false;
}
