There are two types of data in C #: value data and reference data. Distinguish the two types of data during encoding to avoid some minor encoding errors. First, let's talk about what types are value types, such as basic types such as int, float,

I have always wanted to learn plug-in programming. The main reason is that my current customer needs are changing. If I integrate all the functions into an execution file, it is inconvenient to modify and upgrade, to use plug-in programming, you

1. Avoid placing multiple classes in one file. 2. A file should have only one namespace. Avoid placing multiple namespaces in the same file. 3. A file should not exceed 500 rowsCode(Excluding the code generated by the machine ). 4. The code

ArticleDirectory Implement multiple interfaces An interface is a "main class" that contains method signatures but does not implement methods. In this respect, interfaces and abstract classes only contain abstract methods. C #

Write MultithreadingProgramThread Synchronization is inevitable. What is thread synchronization? For example, if there is a variable in a company that records the salary count of someone t = 100, there are two supervisors a and B (that is, the

After such a long time, I re-read C # advanced programming today. I am a little clear about the previously blurred things. Maybe I have recently visited some of the big boys in the garden. Article About It. I once again realized that CLR is in the

It is assumed that there are only two levels of nodes, and the multi-level method is similar. Traverse the node and find the node to be selected based on the selected node text. Treeview. selectednode = selectnode; ///   /// Set the

When C #2.0 was released, we looked back at Java and thought how the language was so slow? But when C # grew to 3.0, it began to show a bloated state. Will this also bring about any chain effect? Six years ago, I was a supporter of Java. At that

In fact, the overload of the constructor is nothing more than implementing the definition of several functions, and then specifying different parameters. The simplicity is not reflected in the definition, but in the use. Only one function name is

It takes a lot of time to create and destroy threads. What is a better solution?Use thread pool! Too many threads waste memory resources. What is the better solution?Use thread pool! What is a better solution for too many threads with lossy

When the derived class and the base class have the same method (the method name is the same, the parameter list is the same as the return value), the method of the derived class can hide the methods of the base class. That is to say, you can create
