Resolved: Convert Decimal To String C#

Question:

How can i convert decimal to string without rounding and with specific format?
It is my value;

var price = 4569.996M;

I want to this result result = "4.569,99" . I can check to culture for seperators like this

customCulture.NumberFormat.NumberDecimalSeparator = ",";
customCulture.NumberFormat.NumberGroupSeparator = ".";

I try some codes

var result = price.ToString("#,##0.##", CustomCulture);
//when you try this result = "4.570"

var result = Convert.ToDecimal(price).ToString("#,#.#########", customCulture);
//when you try this result = "4.569,996"

var result = price.ToString("N");
//when you try this result = "4,570.00"

 var result = price.ToString("N", customCulture);
 //when you try this result = "4.569,996"

My value can be any value. I just want to seperate with specific format and seperate two digit after comma and not rounding when convert to string.

Answer:

Having unwanted digits after the decimal point you have to round the value, the question is how to round it. In your case it seems that you want to truncate (4569.996 -> 4569.99), i.e. round to zero:

  var price = 4569.996M;

  string result = $"{Math.Round(price, 2, MidpointRounding.ToZero)}";

  string result = Math.Round(price, 2, MidpointRounding.ToZero).ToString();

If you have better answer, please add a comment about this, thank you!
