Avoiding multiple if statements in C#

Question

I have a field EmpID (textbox) where user manually enters a 6 digit code. If he enters less than 6 digit then we need to add "0" as prefix to make it a 6 digit code. Example if enters 123, we must make it 000123. If he enters 1234, we must make it 001234.

I want an efficient way for handling this situation. I want to avoid writing multiple if statements. Any better way of doing this?

I recommend using [String.PadLeft](https://msdn.microsoft.com/en-us/library/system.string.padleft(v=vs.110).aspx). — adv12, Sep 30 '16 at 13:18
I wouldn't worry about efficiency. An extra `if` isn't going to bring your machine to its knees. I'd just worry about messy code. — 15ee8f99-57ff-4f92-890c-b56153, Sep 30 '16 at 13:20

Also, make sure wherever you are storing the value it is stored as a string, if you try to store it as a number type you'll lose your padded 0s. — Kevin, Sep 30 '16 at 13:22

It's as simple as this:

tbValue = tbValue.PadLeft(6, '0');

You can do this using PadLeft function as below

myString = myString.PadLeft(6, '0');
