On C # 's small skill region directive

Region directive

Sometimes, to complete a requirement, you might write dozens of lines, hundreds of lines, or even thousands of lines of code.

When the number of code is very large, although you can use very detailed comments to help read, but it is not easy to understand what the code is doing things.

As a result, C # adds a syntax format--region, which is written in the following way:

#region 描述内容
// 代码
#endregion

Region and Endregion must be written in pairs, that is, you cannot write only one region or only one endregion, and they all start with a # number.

What good does it do? Once you've written this, you can fold the code between them, like this:

In this way, for a large segment of the code, you can use this method of folding up, making the entire code easier to read.
