How will you merge strings in C# without using a loop?

Answer:

Suppose, we have some data in the form of string array as under

new string[] { "Hello,", "How", "Are", "You" }

We need to write a C# program that will concatenate the string and will generate the below output
Hello, How Are You

Solution 1: Using Aggregate function

var input = new string[] { "Hello,", "How", "Are", "You" };

var result = input.Aggregate((a, b) => a + " " + b);

Console.WriteLine(result);

Solution 2: Using Join function

var input = new string[] { "Hello,", "How", "Are", "You" };

var result = string.Join(" ", input); 

Console.WriteLine(result);
