I used to write an example of searching on the web. This time I wrote a winform, but I still need to use a regular expression. In a window, there is a richTextBox, an input box, and three buttons: search, the first one, and the last one. Main Code:

1, you have to know that there is a key labled "Caps Lock" 2, you don't even know how large "int" is 3, you do know how large "char" is, but you still don't know how large "Wchar_t" is, if you or your user sadly don't speak English only 4, you

Note: C #3.0, VB9.0 The difference between other keywords (such as abstract and MustInherit) is quite simple. Module: the Module is a static class in C #. However, in other types in the same namespace, the name of the Module class is not required

Generics are a new feature in the C #2.0 language and Common Language Runtime Library (CLR. Generics introduce the concept of type parameters. NET Framework, type parameters make it possible to design the following classes and Methods: these classes

Recently, I briefly reviewed the keywords that need to be used to inherit this feature in C #. Some of the key points are specially sorted out for your convenience. This problem was also mentioned in a Microsoft test and interview: I. in C #, the

In C #, a one-dimensional Array, multi-dimensional Array, and a staggered Array (also called a tooth-like Array) are provided ), because C # itself does not directly support non-0-based (0-based means that the minimum index of the Array is 0) arrays

As we all know, a private member of a class can only be accessed within it! But I don't know if you have noticed that, in fact, a class instance in C # can access the private members of another instance in the same class. Please refer to this
