What is the difference between string and String in c#?

string is alias to String class nothing more nothing less.
Which is a sealed class

“string” is a datatype, whereas “String” represents a class. “string” is an alias for System.String. At execution time both are compiled to the same code. One more difference is the syntax highlighter

We can say both the string and String are same. Even if we can also say string is an alias name of String. But when we use String then we Should include "using System" Namespace otherwise it will generate an Error.Whenever, we hover the mouse on both string and String then it will Show that it comes under System namespace.

" System.String " a.k.a "String" ( capital "S") is a .NET framework data type while "string" is a C# data type. In short "String" is an alias ( the same thing called with different names) of "string". So technically both the below code statements will give the same output.
