how to add certain number of whitespaces to StringBuilder?

Question

How can I add certain number (between 1 and 100) of whitespaces to StringBuilder? ``` StringBuilder nextLine = new StringBuilder(); string time = Util.CurrentTime; nextLine.Append(time); nextLine.Append(/* add (100 - time.Length) whitespaces */); ``` What would be "ideal" solution? `for` loop is ugly. I can also create array where `whitespaces[i]` contains string which contains exactly `i` whitespaces, but that would be pretty long hardcoded array.

Accepted Answer

You can use the `StringBuilder.Append(char,int)` method, which repeats the specified Unicode character a specified number of times:

```
nextLine.Append(time);
nextLine.Append(' ', 100 - time.Length);
```

Better yet, combine both appends into a single operation:

```
nextLine.Append(time.PadRight(100));
```

This would append your `time` string, followed by `100 - time.Length` spaces.

Edit: If you’re only using the `StringBuilder` to construct the padded time, then you can do away with it altogether:

```
string nextLine = time.PadRight(100);
```
