使用 .ToString() 在 C# 中格式化十进制字符串

Question

I have an amount stored in a decimal result :

Eg. decimal result = 1935698.27;

How can I format that to a String using .ToString() so that it looks like this: R 1 935 698,27

It needs to do the following:

• Add R (take note of the space) to the front of the String
• Add spaces to group the value in 3's (ie R 00 000 000 000,00 )
• Replace the . with a ,

This formats according to the South African Rand currency format.

This is what I have:

decimal result = 1935698.27;
string strResult = result.ToString("What should I put here?"); // Need help

// Expected strResult = "R 1 935 698,27"

Any help is much appreciated!

Answer 1

This is built in - just use the South African culture and the currency format specifier .

var result = 1935698.27m;
var ci = new CultureInfo("en-ZA");
var strResult = result.ToString("C", ci);
// strResult is R 1 935 698,27
