C# String Functions And Properties
STRING is another data type in C# programming that represents Unicode characters. It’s a character sequence in which every character is a Unicode character.
Both string and String (Capital S) reveals to be the same in programming structure. A string is just an alias to the System.String. In C#, however, you must use “using System” to access the String. Another distinction is that a string is a reserved keyword, whereas String is a class name. Instead of String, you should always use string.
Let’s have a look at an example:
Source Code-
string str1 = "Hello";
String str2 = "World!";
Console.WriteLine(str1.GetType().FullName);
Console.WriteLine(str2.GetType().FullName);
