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 2 3 4 |
var repeat = string.Join(string.Empty, Enumerable.Repeat(",", 50)); var aggregate = Enumerable.Range(1, 50).Aggregate(new StringBuilder(), (acc, seed) => acc.Append(",")).ToString(); 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

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