In C#, String and string are both keywords that represent a string variable. However, they are not the same.
String is a class in the .NET Framework's System namespace. It is a reference type that represents a sequence of characters.
string is an alias for the System.String class. This means that you can use either keyword to declare a string variable.
Here is an example of how to declare a string variable using both keywords:
// Using the String keyword
String myString = "Hello, world!";
// Using the string keyword
string yourString = "Hello, world!";
Both variables are of type System.String and they contain the same value.
The main difference between String and string is that
String is a keyword, while string is an alias. This means that
String is reserved by the .NET Framework, while string is not.
In general, it is recommended to use the string keyword when declaring string variables. This is because the
string keyword is more concise and easier to read.
