Difference between String and string keyword [Answered]
There's 2 string types that exists in C#. One with a capital letter and one without a capital letter. I've been taught, when I was learning Java, that by convention every primitive type is lowecase and every reference type is PascalCase.
This convention seems to extend to C# as well. Every reference type in C# is CamelCase (+ properties, no idea if that's reference type or not). Everything adheres to this convention except for one which is the String keyword, I've no idea what the hell this is, why it exists and if it was even intended to be there in the language?

They are entirely identical
in C#, there is no difference*
*unless you do something strange
so it's just an alias?
Just use string (lowercase)
in C# there is no distinction between primitive and non-primitive types
Why is it that String and string have different highlighting on my IDE 🤔
Yes
How so?
well, there isn't. there is no such concept as "primitive type"
there are built-in keywords that alias certain classes
string is a keyword that specifically aliases global::System.StringIs it the same for Java as well?
no. java does specifically have primitive types. the only way to say
int is intstring in c# is just an alias for System.String
Like are all primitive types just part of a system package of some sort?
OOOOOOOOOOO
Ok, that makes a lot more sense
I've had an implicit global use in my project that imports the System namespace, I didn't realize I was using System.String, thought I was using some kind of "primitive" type
Ty both of u, that answered my question in it's entirety
Correct
int == System.Int32
float = System.Single
And so onI need to know what the "something strange" is 🙂
well, if you define your own class called String
Ah ok
I was trying to avoid linking that article
But I guess I need to
Defining your own type called string: Chaotic Evil
Can't do that, have to do
@stringDoh
Er, I meant String
That is somewhat more understandable
Maybe you're implementing a DB
