Difference between bytes and byte data types in C #

Question

I noticed that in C # there is a data type byte and Byte . They both say they are of type struct System.Byte and are an 8-digit unsigned integer.

So I'm curious what difference, if any, exists between the two, and why you will use one over the other.

Thank!

Answer 1

The byte keyword is an alias for the System.Byte data type.

They represent the same data type, so the resulting code is identical. There are only some differences in use:

• You can use byte even if the System namespace is not included. To use byte , you must have using System; at the top of the page or specify the full System.Byte namespace.

• There are several situations where C # allows you to use a keyword rather than a frame type, for example:

.

 enum Fruits : byte // this works { Apple, Orange } enum Fruits : Byte // this doesn't work { Apple, Orange } 

Answer 2

byte and System.Byte identical in C #. byte is just syntactic sugar and is recommended by StyleCop (for style guides).

Answer 3

No difference. byte is an alias of System.Byte, in the same way int is an alias of System.Int32, long for System.Int64, string for System.String, ...

Answer 4

C # has a number of aliases for .NET types. byte is an alias for byte , since string is an alias for string , and int is an alias for Int32 . That is, byte and byte are the same actual type.

Answer 5

Nothing, lowercase is a keyword that is an alias for a byte type.

This is pure syntactic sugar.

Answer 6

They are usually the same.

Answer 7

byte is a built-in data type in C #.
System.Byte is a framework that represents byte and provides additional methods such as Parse and TryParse .

byte is an alias of the System.Byte structure. Different .NET languages ​​have different aliases based on the semantics of a particular language, but they are all mapped to specific types in the .NET framework.

Answer 8

also when using reflection ,,

 Type t=Type.GetType("System.Byte"); //works Type t=Type.GetType("System.byte"); //doesn't work, I can see no way to use"byte" directly here without converting it to "Byte"
