c#从TextBox和monthCalendar创建JSON

本文关键字：创建 JSON monthCalendar TextBox | 更新日期: 2023-09-27 18:06:18

现在我有了一个带有文本框和日历的WindowsForm，以及两个按钮(继续和完成)。用户必须在框中输入文本并选择日期。如果他按下continue，则必须将文本和日期写入json文件。然后，相同的窗口应该再次打开，他可以输入新的值。最后，如果他单击finish按钮，Values应该被写入文件，窗口可以关闭。(用户应该在输入第一个值后点击完成)。我已经创建了一个get/set类:

class Nachrichten_Felder
{
    public string Nachrichten { get; set; }
    public string Datum { get; set; }
}

我怎样才能得到这份工作?我真的不知道如何将文本和日期写入json并再次打开窗口…
