C# convert int to string with padding zeros?

I am trying to generate a random number however in the ranges I have included “0000000, 9999999” I want it to show these zeros when a number is generated for example the following outputs would be:

“00037544”
“01659369”
“75484957”
“00000001”

I am using the:

    int num = rnd.Next(0000000, 9999999);

The problem with that is sometimes it will generate:

“1648”
“947596”
“18500” etc

Is there something that im missing?

Thanks for looking

You have to convert it to the string and then use PadLeft.

string number = num.ToString().PadLeft(7, '0');

Or Simply

string number = num.ToString("0000000");
