How can I have Decimal.TryParse parse 0.0?

Question

Is there a way to get Decimal.TryParse to parse a string value of "0.0" or "00.00" or "000.000" as 0?

I have tried setting NumberStyles to Any.

Using the InvariantCulture, decimal.TryParse does successfully interpret all of those strings as zero. This code, for example:

decimal num = 66;
foreach (var str in new string[] { "0.0", "00.00", "000.000" })
{
    if (!decimal.TryParse(str, out num))
    {
        Console.WriteLine( "fail" );
    }
    Console.WriteLine(num);
}

Produces this output:

0.0
0.00
0.000

Perhaps, the issue is printing the values, not parsing the values? If that's the case, simply use a format string that specifies that the decimal places are optional.

Console.WriteLine( num.ToString( "#0.#" ) );

Produces

0
0
0
