We will try to return a string like: “I can text whatever I want with 4 different options in C#. ” with String Interpolation, String Format, String Concat, and String Builder.
public class StringOptions
{
private string data1 = "4";
private string data2 = "C#";
public string StringInterpolation() => ($"I can text whatever I want with {data1} different options in {data2}.");
public string StringFormat() => string.Format("I can text whatever I want with {0} different options in {1}.", data1, data2);
public string StringConcat() => "I can text whatever I want with " + data1 + " different options in " + data2 + ".";
public string StringBuilder() => (new StringBuilder()).Append("I can text whatever I want with ").Append(data1).Append(" different options in ").Append(data2).Append(".").ToString();
}
