Best way to repeat a character in C#

What about this:

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

Where n is the number of times you want to repeat the string.

Or better:

static string Tabs(int n)
{
    return new String('\t', n);
}

string.Concat(Enumerable.Repeat("ab", 2));

Returns

"abab"

And

string.Concat(Enumerable.Repeat("a", 2));

Returns

"aa"

from...

Is there a built-in function to repeat string or char in .net?

In all versions of .NET, you can repeat a string thus:

public static string Repeat(string value, int count)
{
    return new StringBuilder(value.Length * count).Insert(0, value, count).ToString();
}

To repeat a character, new String('\t', count) is your best bet. See the answer by @CMS.
