Recently I’ve been asked by friend of mine, how to generate string consisting of 50 commas. I came up with these three code snippets:

1
var repeat = string.Join(string.Empty, Enumerable.Repeat(",", 50));
2
var aggregate = Enumerable.Range(1, 50).Aggregate(new StringBuilder(),
3
                                                 (acc, seed) => acc.Append(",")).ToString();
4
var usingArray = string.Join(",", new string[51]);//must be 51, separator is not inserted after last index

Although all of these lines produce appropriate outcome, it’s seemed to me that there is some simpler way to accomplish this task. After a little bit of searching, it turned out, that it is possible to generate string consisting of same characters using one of string’s constructors

1
var usingConstructor = new string(',', 50);
