How to format number 1234567 to 1,234,567 in C #?

Answer 1

The format options for Int32.ToString () see here or here .

For example:

string s = myIntValue.ToString("#,##0"); 

String.Format can use the same format options as in

 string s = String.Format("the number {0:#,##0}!", myIntValue); 

Please note that , in this format, do not specify "use a comma", but rather, you should use a grouping of characters for the current culture, in the provisions of culturally specific.

Thus, you get "1,234,567,890" for PL-PL or "1,23,45,67,890" for hi-IN.

Answer 2

Using the current thousands locale delimiter:

 int n = 1234567 ; n.ToString("N0"); 

Or use the overload for ToString, which takes the culture as a parameter.

Answer 3

 var decimalValue = 1234567m; var value = String.Format("{0:N}", decimalValue); // 1,234,567.00 

or without cents

 var value = String.Format("{0:N0}", decimalValue); // 1,234,567 

Answer 4

Try String.Format ("{0: ##, ####, ####}", 8958712551)

Answer 5

 string formatted = string.Format("{0:##,#}", 123456789); 

It depends on the culture of your computer. Some countries use commas, some countries use periods. On my computer, the output was: 123.456.789
