Is there a “Space(n)” method in C#/.Net?

Use this constructor on System.String:

new String(' ', 10);

Here’s a neat extension method you can use, as well (although it’s probably better just to use the String constructor and save the extra method call):

public static class CharExtensions
{
    public static string Repeat(this char c, int count)
    {
        return new String(c, count);
    }
}
...
string spaces=" ".Repeat(10);
