The labels must all be uppercase, the middle space is underlined _ instead, and should start with _, for example:_a_label_example:the label is defined so that it is sufficiently different from other code elements. Five, the name spaceUsually, a project uses a namespace, usually does not need to use the Namespace statement, but in the project option "Root Namespace", the use of the root namespace can make the code more neat, easy to modify, this is the full a

C # Coding Specification
In order to make the software easier to maintain later, it is necessary to set up a coding standard.
It has long been discussed and studied by the discovery of this matter:

Today, I finally finished writing this series of coding specifications. This coding specification was counted as reading relevant books. It took a whole month before and after that, and it was my painstaking work.I didn't plan to write this series so long, but I searched the relevant online materials during the writing process. Later I found that there were very few C

C # Coding specifications
In the later stage of the OA project, we need to optimize the overall code, organize and summarize some experiences and coding specifications, and share them with you.
The most fundamental difference between programmers and beginners is that they always consider efficiency issues, because this era is an efficiency-oriented era. If effic

Call the static member function, which can be accessed with the member access operator (.) and (-) call a static member function for an object of a class or pointer to a class object, or you can use the following format directly:Class name >::such as: Myclass::getsum (), invokes the static member function of the class.However, you should follow
Coding
I. Coding rulesThe idea of BASE64 encoding is to encode the data using 64 basic ASCII characters. It splits the data that needs to be encoded into a byte array. A group of 3 bytes. Arrange the 24-bit data in order, then divide the 24-bit data into 4 groups, that is, 6 bits per group. Then fill a byte with two 0 in front of each group's top digit. This encodes a 3-byte-A-group of data back into 4 byte

Foreach has better execution efficiency thanThe average time spent by Foreach is only 30% of that of for. When both for and foreach can be used through the test results, we recommend using a more efficient foreach.In addition, the write time using for is about 10 times the read time.
