Choose one of the following ways for padding a number with zeros:
Note that a number can be converted to string via ToString().

1. using the Format method of string

Code:

string strTemp = String.Format("{0:0000}", aStr);

2. using PadLeft() or PadRigh() method of string

Code:

aStr.PadLeft(nTotalWidth, '0');

Padding with spaces

Code:

aStr.PadLeft(nTotalWidth);

Padding right

Code:

aStr.PadRight(nTotalWidth);

3. classic way

Code:

strTemp = "0000" + aStr;
strTemp = strTemp.Substring(strTemp.Length - 4);
