I need to pad the output of an integer to a given length.
For example, with a length of 4 digits, the output of the integer 4 is "0004" instead of "4". How can I do this in C# 2.0?

To pad a numeric value with leading zeros to a specific length. Determine how many digits to the left of the decimal you want the string representation of the number to have. Include any leading zeros in this total number of digits.
Use the String. format() method to pad the string with spaces on left and right, and then replace these spaces with the given character using String. replace() method. For left padding, the syntax to use the String.
Python String zfill() MethodThe zfill() method adds zeros (0) at the beginning of the string, until it reaches the specified length. If the value of the len parameter is less than the length of the string, no filling is done.
Use the string.Format command.
output = String.Format("{0:0000}", intVariable);
