Add same value into string multiple times

Question

I'm trying to make a simple tab space between words, using a dynamic ammount. How would I do this?

Simply like this:

string p1 = keysC[pos]+"="+valsC[pos];
int tabs = (60 - p1.Length) / 4;
wr.WriteLine(p1 + ("\t" * tabs) +"//"+comsC[pos]);

what are you asking for ? What doesn't work ? What is the expected result ? Is this a question or an answer ? — Cosmin Vană

Side note: not everyone have tabs set to 4 (I believe in most cases default is actually 8). Consider instead padding with spaces (almost same code, but will display properly in more cases). — Alexei Levenkov

The String contructor has an overload for that.

string p1 = keysC[pos]+"="+valsC[pos];
int tabs = (60 - p1.Length) / 4;
wr.WriteLine(p1 + new string('\t', tabs) +"//"+comsC[pos]);

Note that the first argument of the constructor is a char and not a string.

You can use the string constructor:

string allTabs = new string('\t', tabs);

Try this:

string spacing = new String('\t', tabs);

Sounds like just need to write a function that repeats the same string N number of times

static string RepeatString(string source, int times) { 
  var builder = new StringBuilder(source.Length * times);
  for (int i = 0; i < times; i++) {
    builder.Append(source);
  }
  return builder.ToString();
}

Note that if you only care about repeating a char like \t then use @Vache's answer of new string(theChar, theCount)

+1. Or even String.Join(null, Enumerable.Repeat(source, times));

@AlexeiLevenkov: which would be less efficient than the constructor.

@TimSchmelter - indeed for of single character as in actual OP's case one should use constructor.
