During product project implementation, we will inevitably encounter different functions because the project service objects are different. In this way, it is time-consuming to recompile the entire solution after each modification. In fact, with the

(1) The usage rule for referencing the Namespace using as the Namespace instruction is: using Namespace. NET programs, the most common code is to introduce the System namespace at the beginning of the program file, the reason is that the System

The Timer control similar to WinForm is no longer available in WPF. Therefore, you need to use the DispatcherTimer class to implement scheduled execution events similar to Timer. This event is implemented using delegation. DispatcherTimer classInIn
