如何解码datetimepicker [英] How do decode datetimepicker

问题描述

dateTimePicker1.Value.ToString（）= prop.AdmissionYear;



我尝试过：



dateTimePicker1.Value.ToString（）= prop.AdmissionYear;

dateTimePicker1.Value.ToString() = prop.AdmissionYear;

What I have tried:

dateTimePicker1.Value.ToString() = prop.AdmissionYear;

推荐答案

DateTimePicker类（System.Windows.Forms） [ ^ ]。

该代码有很多错误...

There are loads of things wrong with that code...

dateTimePicker1.Value.ToString() = prop.AdmissionYear;

字符串是不可变的，所以当你尝试为字符串对象分配一个新的值时，你期望发生的事情我不知道。您可以为字符串变量赋值，但不能为对象赋值。



日期不仅仅是一年：它们也有月和日。因此，您可能希望使用年份来生成一个适当的日期，该日期将在学年开始时：

Strings are immutable, so quite what you expect to happen when you try to assign a string object a new value I don;t know. You can assign a value to a string variable, but not to an object.

Dates are not just a year: they have months and days as well. So you probably want to use the year to generate a "proper" date which would be around the start of the academic year:

dateTimePicker1.Value = new DateTime(int.Parse(prop.AdmissionYear), 9, 1);
