Building Strings
Concatenation and StringBuilder.
Joining Strings With +
The simplest way to build a string is to join pieces with the + operator.
This is called concatenation. It works well for a few pieces, like combining a greeting with a name.
class Program
{
static void Main()
{
string name = "Sam";
string greeting = "Hi, " + name;
System.Console.WriteLine(greeting);
}
}String Interpolation
Interpolation is a cleaner way to insert values into text.
Put a $ before the string and wrap variables in curly braces. The values are dropped into place automatically.
class Program
{
static void Main()
{
string name = "Sam";
int age = 9;
System.Console.WriteLine($"{name} is {age}");
}
