Adding spaces between strings

Question

What's the best way of adding spaces between strings

myString = string.Concat("a"," ","b")

or

myString = string.Concat("a",Chr(9),"b")

I am using stringbuilder to build an XML file and looking for something efficient.

Thanks

Edit ~ Language VB.NET

Answer 1

Create your XML file with the XmlDocument class. Your wasting your time creating a string from scratch.

Answer 2

String.Join is a static method that can take the separator (in this case, " ") and an array of strings.

string sentence = String.Join(" ", new string[] { "The", "quick", "brown", "fox" });
