Dotnet Specify the size of the file display

In project development, it is sometimes necessary to control the size of the file, such as the need to specify the size of the file as bytes, TB, etc. Now provides a method that implements the size of the specified file,

Provides: "bytes", "KB", "MB", "GB", "TB" and other dimensions of the control options, the method code can be used directly in the project, improve project development efficiency.

The above is just a file size to perform an arithmetic operation that implements the functions described above.
