Today I read Anders's interview with C #4.0, and I feel that C #4.0 is a forced thing. In today's era of Dynamic Language, Ruby, JavaScript, XML, and other dynamic languages are widely used in various places, while C # Is a static language, how to

During this time, I started to look at the design mode. I just looked at the singleton mode. The most concise method to achieve it is: Class Singleton { Public   Static   Readonly Singleton instance =   New Singleton (); Private

Many non-generic collection classes have their corresponding generic collection classes. Below are common non-generic collection classes and their generic collection classes: Non-generic collection class Generic collection class

In my understanding, generics are like a bag that can hold everything. we certainly don't want to use this bag to pack delicious food and garbage. for example, if you go to the supermarket to buy a package of cookies, the waiter will give you a bag

Many non-generic collection classes we use mainly include the arraylist class and the hashtable class. We often use hashtable to store the information to be written to the database or returned. In this case, we need to constantly convert the data

Class program {static void main (string [] ARGs) {console. writeline (next ("abc123def345ghi"); console. read ();} Private Static string next (string s) {If (! Isnumber (S. substring (S. length-1, 1) S = S + "0"; matchcollection coll = RegEx.

In. net, the callable DLL (Dynamic Link Library) file is actually a class library. We can write a class and compile it into a DLL file. In other projects, we can directly call the compiled DLL file, instead of repeatedly writing this

In the process of developing winfrom with C. Progress bars are often used to display progress information. At this time, we may need to use multiple threads. If we do not use multiple threads to control the progress bar, the window will easily be
