String Format for Int [C#]

Integer numbers can be formatted in .NET in many ways. You can use static method String.Format or instance method int.ToString. Following examples show how to align numbers (with spaces or zeroes), how to format negative numbers or how to do custom formatting like phone numbers.

Add zeroes before number

To add zeroes before a number, use colon separator „:“ and write as many zeroes as you want.

[C#]
String.Format("{0:00000}", 15); // "00015" String.Format("{0:00000}", -15); // "-00015"

Align number to the right or left

To align number to the right, use comma „,“ followed by a number of characters. This alignment option must be before the colon separator.

[C#]
String.Format("{0,5}", 15); // " 15" String.Format("{0,-5}", 15); // "15 " String.Format("{0,5:000}", 15); // " 015" String.Format("{0,-5:000}", 15); // "015 "

Different formatting for negative numbers and zero

You can have special format for negative numbers and zero. Use semicolon separator „;“ to separate formatting to two or three sections. The second section is format for negative numbers, the third section is for zero.

[C#]
String.Format("{0:#;minus #}", 15); // "15" String.Format("{0:#;minus #}", -15); // "minus 15" String.Format("{0:#;minus #;zero}", 0); // "zero"

Custom number formatting (e.g. phone number)

Numbers can be formatted also to any custom format, e.g. like phone numbers or serial numbers.

[C#]
String.Format("{0:+### ### ### ###}", 447900123456); // "+447 900 123 456" String.Format("{0:##-####-####}", 8958712551); // "89-5871-2551"

// CString -> int convert

CString strNum = _T("5");

int nNum = _ttoi(strNum);

int nNum = atoi(strNum);

// int -> CString convert

int nNum = 5;

CString strNum;

strNum.Format(_T("%d"), nNum);


// CString -> double

CString strNum = _T("5.5");

double nNum = _wtof(strNum);

double nNum =  atof(strNum);


// double -> CString

double nNum = 5.5;

CString strNum;

strNum.Format(_T("%f"), nNum);
