Hi,
Try this:


 decimal d = Convert.ToDecimal(textbox.Text);
 string szFinalText = d.ToString("F");

You can limited decimal places to 2 in many ways.
see below snippet


decimal d = 100.123456M;

decimal dc = Math.Round(d, 2);
d.ToString("#.##");
d.ToString("F");
OR
 public void RoundDecimalTo2dp()
    {
        decimal original = 3.14159265m;
        decimal final = Math.Round(original, 2, MidpointRounding.AwayFromZero);
        Assert.AreEqual(3.14m, final);
    }

OR
decimalVar.ToString("F");

This will:

Round off to 2 decimal places eg. 23.456 => 23.46

Ensure that there are always 2 decimal places eg. 23 => 23.00, 12.5 => 12.50

Ideal for currency and displaying monetary amounts
