  In C #, there is a stopwatch class: stopwatch. This class can be used to conveniently test the code running time. To use stopwatch, add a namespace, System. Diagnostics. The usage is as follows: 09              Stopwatch timer = new Stopwatch()

When we were doing A Winform form program, we encountered the following problem: when Form B is closed, Form A is also closed. The solution is as follows: when Form B is closed, A value is returned to form A. When A accepts this value, the close

In the past two days, the WinForm program needs to be implemented, and an ASP inventory change function module needs to be converted into a Winform program. Therefore, this situation occurs when values are transferred between forms, I used to do

When you study C # In actual work, you may ask: why do we need to provide some existing functions (for example, some functions in Windows, some methods that have been compiled in C ++) to rewrite the code, can C # directly use these existing

C # There are two solutions to call the Delphi interface: 1. Compile the Delphi program into a COM component and reference the COM component in C. II. The DLL file of the unmanaged call Dephi.   Here we will mainly explain the second method. before

Hill sorting Hill sorting is to segment the group for insertion sorting.If you want to improve your C # programming skills, we can discuss with each other.For example, the following program does not implement polymorphism. Using System;Public class

It is often seen that many programs use Thread as a Timer (Timer), such as regularly checking data, regularly clearing cache or something. Just like the following codeCode Code highlighting produced by Actipro CodeHighlighter

When completing the configuration, You need to count the frequency of occurrence of words (the word has been rough cut) in the Chinese corpus. Think of the number of each character in the statistical string when we start to learn the C language, I

In the previous article, how does Java quickly boil to C #? (1): similar methods. We started one of the topics in C # and Java: similar methods. In this section, we will illustrate how similar it is. Let's use a simple factory model example to

Before C #2.0, if a method or variable needs to use a delegate, you must create a naming method and input the name at the place where the delegate is required. for example, a data processing method for int type is used to filter out an odd element

On the Internet, I often see articles about the three basic features of object-oriented, "inheritance", "encapsulation", and "polymorphism". I think this is the most unreliable term. This article will talk about one of the features mentioned here:

In C #, use Delegate d = Object. create a delegate. In terms of implementation, this delegate object holds a strong reference (System. object). If the user has special requirements, for example, "the source Object should be recycled in a timely
