How to use String.Format to show only cents and omit dollars

Question

I want to display only tenths of decimal.

decimal d = 44.22m;

var s = d.ToString("");

How to make this s == "22" true ?

PS: i'm well aware i can do some math but i'm want to display tenths in WPF using only Binding and StringFormat

I really didnt want to complicate things but if there's no StringFormat available, i'll use a converter — Dejan Dakić, Oct 24 '14 at 09:26
I don't think that you get an answer which doesn't need to use maths and only needs `String.Format` or `ToString`. By the way, the question would be easier to understand if you'd use a title like _"How to use String.Format to show only cents and omit dollars"_ — Tim Schmelter, Oct 24 '14 at 09:31
@TimSchmelter: I also dont think there is a pure -String.Format- way to get the cents. — C4d, Oct 24 '14 at 09:37

It is not the best but it works :

        decimal d = 44.22m;
        string ds = d.ToString().Remove(0, (d.ToString().IndexOf(',') + 1));

decimal d = 44.22m;

Regex regex = new Regex(@"\d*(?=m)");
Match match = regex.Match(d);
if (match.Success)
{
        Console.WriteLine(match.Value);
}

If you need a lot of operations, maybe set up a function for this step!? I guess using String.Format only wouldnt work.

int getDecimals (decimal d)
{
    try
    {
        int s = Convert.ToInt32(string.Format("{0}", d.ToString().Split('.')[1]));
        return s;
    }
    catch { //whatever u want// }
}

// ==> //

decimal d = 44.22m;

string s = getDecimals(d).ToString();

Original Post Code:

string outPut = "0";
if (MyValue.ToString().Split('.').Length == 2)
{
outPut = MyValue.ToString().Split('.')[1].Substring(0, MyValue.ToString().Split('.')[1].Length);
}
Console.WriteLine(outPut);

Modified to your requirements:

decimal d = 44.22m;
string outPut = "0";
if (d.ToString().Split('.').Length == 2)
{
    outPut = d.ToString().Split('.')[1].Substring(0, d.ToString().Split('.')[1].Length);
}
Console.WriteLine(outPut);
