Numbers formatting in C#

I have numbers like this: -1.0001 -10000.01

And I need to get this: -1.0001 -10000,01

Requirements: - Decimal separator is "," - Group separator is " " - part of a number after the comma can have different length, that depends from actual data.

I tried to use this mask: "### ### ##0.####" to format numbers. When number is big - all is ok, but when it is small - I get spaces from the left of a number. I get this: "- 1,0001" "- 10 000,01"

As I understand these spaces are from the mask I used.

There are some workaround ways but they are not so beautiful and aesthetically wright.

Is there any way to do this correctly?

Thank you!

Try using the NumberFormatInfo class to format your number. I used the code below to check my answer and it worked for the large/small cases I tested with:

    static void Main(string[] args)
    {
        double smallNumber = -1.01;
        double smallNumberMoreDigits = -1.0001;
        double bigNumber = -100000.001;
        double longNumber = 2.2347894612789;

        Thread.CurrentThread.CurrentCulture = new CultureInfo("ru", false);            

        Console.Out.WriteLine(smallNumber.ToString("#,0.####"));
        Console.Out.WriteLine(smallNumberMoreDigits.ToString("#,0.####"));
        Console.Out.WriteLine(bigNumber.ToString("#,0.####"));
        Console.Out.WriteLine(longNumber.ToString("#,0.####"));

        Console.Read();
    }

EDIT: A quick bit of detective work (I looked at your profile) tells me you're in Russia. Are you looking for the General Russian number formatting? I've changed the code above. Take a look and see if it fits your requirements. It gives me the following results:

-1,01 -1,0001 -100000,001

SECOND EDIT: Added masking to get a better result on decimal places.

The spaces were automatically removed by stackoverflow when you posted but I think you can solve your problem by just using Trim like 

something.ToString("### ### ##0.####").Trim();
