c# secure coding

Everyone will write code! A few months of programming experience allows you to write "runable Applications ". It is easy to run, but coding in the most efficient way requires more effort!You know, most programmers are writing "executable code" instead of "efficient code". As we mentioned above, do you want to be the "most distinguished professional" of your company? Writing "efficient code" is an art. You must learn and practice it. Naming Conventions

VS's That "New Item dialog" comes out very slowly and affects the mood.When you find that you need to define a class, the c

C # explain the basic content of operators and expressions frequently used in coding,[Preface] As the saying goes, it's better to hit the iron, so let's sum up a little bit if you learn something about it.[Overview] This summary mainly summarizes the operators, Operation expressions, and some additional content when talking about operators and operation expressions.[Operator] The operators are similar to th

Huffman tree, also known as the optimal binary tree, is a tree with the shortest length of the weighted path, which can be used to construct the optimal coding for information transmission and data compression, and is a widely used two-fork tree.several basic concepts related to: 1. path : The branching sequence from one node to another in the tree forms the path between two nodes2. path length : The number of branches on the path is called the path l

1. String Operation Security 1.1 ensure that all strings are null-terminatedThe C language takes ' Terminator ' as a string, or null terminator.The failure to use the null terminator correctly can result in a buffer overflow and other undefined behavior.To avoid buffer overflows, some dangerous functions are often replaced with a relatively secure string manipulation function that restricts the number of c
