C# Strings
C# Strings
Strings are used for storing text.
A string variable contains a collection of characters surrounded by double quotes:
Example
Create a variable of type string and assign it a value:
string greeting = "Hello";A string variable can contain many words if you want:
String Length
A string in C# is actually an object, which contains properties and methods that can perform certain operations on strings. For example, the length of a string can be found with the Length property:
Example
string txt = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
Console.WriteLine("The length of the txt string is: " + txt.Length);
Other Methods
There are many string methods available, for example ToUpper() and ToLower(), which returns a copy of the string converted to uppercase or lowercase:
Example
string txt = "Hello World";
Console.WriteLine(txt.ToUpper()); // Outputs "HELLO WORLD"
Console.WriteLine(txt.ToLower()); // Outputs "hello world"
