Ladies and gentlemen, crossing, the last time we talked about the example of a socket communication model, this time we say the example is: socket knowledge system diagram . Gossip Hugh, words return to the positive. Let's talk C chestnuts

1. Overloading:Overloading is a series of functions in which a class, like a function name, has a different parameter type or number of argumentsIt is important to note that it is independent of the return type. class test{ public : void

Process: Just like you run a program, open a Notepad, and so on. A process has at least one thread that can have multiple threads "concurrent" execution in the same process. In fact, multi-threaded concurrent execution, is the multiple threads are

The CLR supports two basic types: value types and reference typesSo what data types are value types and what data types are reference types? Take a look at the following simple summary:Value type:All numeric types (long int short byte ulong uint

When copying the online code, often the first column of each line will have a serial number, if one or two rows we can manually remove, but hundreds of rows of time will be very painful.Here's how to remove the number before the code:

C # is popular for its ease of use and powerful features. PowerBuilder as C/s MIS development tool, very simple and flexible, short development time, low development and maintenance costs, has been the first choice of SME information management
