In C#, what is the difference between Byte and Byte data types? [duplicate]


In C#, I realized that there is a byte and a Byte data type. They both claim to be of the struct System type. An 8-digit unsigned integer is represented by a byte.

So, what is the difference, if any, between the two, and why would you choose one over the other?

Solution #1

The byte keyword is a System alias. The data type byte is used to describe the size of a byte.

Because they represent the same data type, the code generated is similar. There are only a few distinctions in usage:


enum Fruits : byte // this works
  Apple, Orange

enum Fruits : Byte // this doesn't work
  Apple, Orange

Please see the link for a complete list of aliases.

Solution #2

byte and System are two terms that are used interchangeably. In C#, byte and byte are the same thing. StyleCop recommends the use of byte as a syntactic sweetener (for style guidelines).

There’s no difference. System is an alias for byte. In the same manner that int is an alias for System, Byte is an alias for Byte. To System, int32, long To System, int64, string a string…

Solution #4

The.NET types have a number of aliases in C#. In the same way that string is an alias for String and int is an alias for Int32, byte is an alias for Byte. In other words, the real types byte and byte are the same.

Solution #5

The lowercase one is a keyword that serves as an alias for the Byte type.

This is syntactic sugar in its purest form.
