Strings | C# By Examples

Strings #

In C#, strings are represented by the string type, which is actually an abbreviation for the System.String object.

Strings are immutable by default, meaning that the value of a string cannot be changed once it is declared.

In this example, the += operator is used to append the string “World” to the end of the string “Hello”.

Actually, this creates a new string object, and then the original string object is discarded.

string a = "Hello";
a += " World";
Console.WriteLine(a); // output: Hello World

This is the same as the previous example, but it uses the full System.String type instead of the abbreviated string type.

System.String a = "Hello";
a += " World";
Console.WriteLine(a); // output: Hello World

You can use """ syntax to create a multiline string.

string body = """
{
    "name": "John",
    "age": 30
}
""";
Console.WriteLine(body);
