Join multiple strings with single string

Friday, 23 December 2011 00:10

There are two ways to join multiple strings: using the + operator that the String class overloads, and using the StringBuilder class. The + operator is easy to use and makes for intuitive code, but it works in series; a new string is created for each use of the operator, so chaining multiple operators together is inefficient.

Example: 1



string two = "two";

string str = "one " + two + " three";

System.Console.WriteLine(str);

Example: 2



string two = "two";



        System.Text.StringBuilder sb = new System.Text.StringBuilder();

        sb.Append("one ");

        sb.Append(two);

        sb.Append(" three");

        System.Console.WriteLine(sb.ToString());



        string str = sb.ToString();

        System.Console.WriteLine(str);
