Hi Expert!

A quick and simple question...

Why does C#.Net allow the declaration of the string object to be case-insensitive?

String sHello = "Hello";
string sHello = "Hello";
Both the lower-case and upper-case S of the word String are acceptable and this seems to be the only object that allows this.

Can anyone explain why?

Hi Chintoo!

Read below line carefully, that remove your doubt between "string" and "String" 

"string" is a language keyword while "System.String" is the type it aliases.

Both compile to exactly the same thing, similarly:

int is System.Int32
long is System.Int64
float is System.Single
double is System.Double
char is System.Char
byte is System.Byte
short is System.Int16
ushort is System.UInt16
uint is System.UInt32
ulong is System.UInt64

I think in most cases this is about code legibility - all the basic system value types have aliases, I think the lower case string might just be for consistency.
