用千位分隔符转换格式化的十进制字符串

Question

I could not find answer which combines the two here.

I am getting from the database for example 8120.349 and looking to convert this to two decimal and thousand seperator. so ideal output string I am looking for here is 8,120.35

Currently I am converting to two decimal using

MaxValue.ToString("F2") //maxvalue is decimal

this outputs me 8120.35

tried adding this for thousand seperator after looking at few answers.

String.Format("{0:n}", MaxValue.ToString("F2"))

this still gives me same output.

any ideas here?

Answer 1

You could use MaxValue.ToString("N2")

Answer 2

You should use : Standard Numeric("N") Format Specifier

double number = 8120.349;

var stringFormatted = number.ToString("n");

Answer 3

您也可以使用手工制作的格式，

string.Format("{0:#,##0.00}", 8120.349)
