I have searched the internet and there are many ways to use skin for forms, but in C #, this method is the easiest.Use the skinengine control provided by irisskin2.dll to add skin to the form.Procedure: 1. Add the control skinengine.1. Right-click

I want to change my job after the end of next year. So recently, I need to record some of C #'s previous missed knowledge, neglected, unvalued, and vague knowledge, in case you cannot find a job because of some basic things during the interview.

Preface This is a simple wheel I made to put it on the MACOs. Today, I checked some implementations of JUnit 3.8 and decided to use C # to imitate the famous JUnit framework in Java. Implementation requirements: For some user-defined classes,

Some time ago, I have read some concepts about C # norm and some applications, but I still don't quite understand it. Today, I accidentally reviewed what I 've seen before and finally understood it. So I really want to learn about it.It can also be

After some forms are minimized, hide the pallets from the form to the bottom right corner.ProgramGenerally, the processing of several events and properties is not displayed in the task bar. After you click minimize, the system hides the pallets in

C # super-class and easy-to-use classes Let's take a look at the following question: when the user input is 169 years old, it obviously exceeds the limit of human beings, and we need to use attributes to limit it.   Figure 1. Attribute Set

After completing some basic C # courses, I started to study C #'s important components, classification and method knowledge today. The following is what we will introduce: 1. Method-related 2. Category-related   I.
