C# line break every n characters

Question

Suppose I have a string with the text: \"THIS IS A TEST\". How would I split it every n characters? So if n was 10, then it would display:

\"THIS IS A \"
\"T         


        

Answer 1

Probably not the most optimal way, but without regex:

string test = "my awesome line of text which will be split every n characters";
int nInterval = 10;
string res = String.Concat(test.Select((c, i) => i > 0 && (i % nInterval) == 0 ? c.ToString() + Environment.NewLine : c.ToString()));
