How to add "123" to the beginning of a string and pad it to be exactly 12 chars in C#?

In C#, you can add "123" to the beginning of a string and then pad it to be exactly 12 characters using the PadLeft method. Here's how you can do it:

string originalString = "456"; string prefixedAndPaddedString = "123" + originalString.PadLeft(9, '0'); Console.WriteLine(prefixedAndPaddedString);

In this example, we have an originalString with the value "456". We then concatenate "123" to the beginning of the originalString, and finally, we use the PadLeft method to pad the resulting string to a total length of 12 characters by adding leading zeroes ('0').

The PadLeft method takes two arguments: the total length to which the string should be padded, and the character used for padding. In this case, we specified 9 as the total length (to account for the "123" prefix) and used '0' as the padding character.

After executing the code, prefixedAndPaddedString will have the value "123000000456".
