join an array of substrings into a string in csharp

To join an array of substrings into a string in C#, you can use the string.Join method. Here's how:

main.cs
string[] substrings = { "hello", "world" };
string joinedString = string.Join("", substrings);
// Result: "helloworld"

// You can also specify a separator between the substrings
string joinedStringWithSeparator = string.Join(" ", substrings);
// Result: "hello world"
269 chars
8 lines

In the above code, we are using the string.Join method to join an array of substrings. The first parameter of this method specifies the separator to use between the substrings. In this case, we are passing an empty string in order to concatenate the substrings together without any separator.

The second parameter of the string.Join method is the array of substrings that we want to join. In this example, it's the substrings array. When the method is called, it returns a single string that contains all the substrings joined together.
