Leave only two decimal places after the dot

I've this problem and can't find a solution.
This is super easy and i don't know why can't i find a solution.
Problem:
if a value returns for example "16.60", in c# i'll read "16.6", but i need 0 as well, because of paypal API, wich only accepts a value with no decimal numbers, or if it has to have decimal numbers the minimum and maximum must be 2.
So how can i make this?
i've tried this:
string value_f = "16,6";
decimal value_f_d = decimal.Parse(value_f);
value_f_d = (decimal)Math.Round(value_f_d, 2);
value_f = value_f_d.ToString("#.##");
value_f = value_f.Replace(',', '.');
i want this output: 16.60, but gives this: 16.6
string output = value_f_d.ToString("#.00", CultureInfo.InvariantCulture);
(using System.Globalization in your using declarations at the top)

This is my code:
decimal test1 = 190.5m;
decimal test2 = 191.5m;
var testResult1 = Math.Round(test1, 0); // =190 It should be 191!!!!
var testResult2 = Math.Round(test2, 0); // =192 Correct.
Is there a way I could get the correct result? Maybe another library instead of System.Math?
This is by design. Albeit not what we have grown up with.

I'm making a simple calculator in c# and and everything works well until I try dividing numbers that should give decimal places. How to display 2 decimal places in these cases?
I've tried putting #.## after .ToString.
{label1.Text = (divide / Convert.ToInt64(label1.Text)).ToString("#.##");}
I expect the output of 5/4 to be 1.25, but it is 1.
convert the number to float instead of int,
{label1.Text = ((float)divide / float.Parse(label1.Text)).ToString("n2");}

Why does 0.ToString("#.##") return an empty string instead of 0.00 or at least 0?

I have several decimal numbers that I need to show as strings (no need for decimal places). I use the following code:
mytextblock.text= mydecimalnumber.ToString("#");
However this code will show nothing if the number is 0. I need to display a "0" instead of an empty string. I can do this using if and else but I don't think this is the best solution to do with many decimal variables.
Some user "David.." posted this answer and it worked for me but then he deleted it later:
He mentioned that ToString("#") will only show digits that are not zeros.
In order to default to 0, I should use ToString("0")

If I got decimal number like 14.50 and I want to be represented like decimal 10.2
0000000014.50
how can I do this?
Thank you
Use custom numeric format string:
var value = 14.50m;
string valueString = value.ToString("0000000000.00");
0 is a placeholder: Replaces the zero with the corresponding digit if one is present; otherwise, zero appears in the result string.
If you don't have an issue with the data type being converted to string then you could use Padding in c#.

Formatting a float to 2 decimal places
If I have a float that consists of something like 153.2154879, is there any way to convert it to string but only show 4 decimal places? I know I can format it using "000.000", but the front number doesnt always have to be 3 digits. So is there a way to show all the front numbers (153), but only the first 4 characters after the point in a string?
Something like this should do:
your_number.ToString("0.####");
This will show a max of 4 decimal places.
I usually use a format string like "#0.0000".
You can use the C# function Math.Round function.
float a= 153.213456;
Math.Round(a,3);
this would round up the number to 153.213
then get convert it to string.
