How to change 1 to 00001?

Question

I want to have numbers with a fixed digit count.

example: 00001, 00198, 48484

I can do like this:

    string value;
    if (number < 10)
          


        

Answer 1

If you wish to return 5 digits numbers, you should use the PadLeft() function;

int Value = 101;
char pad = '0';
String sValue = Value.ToString();

sValue  = sValue.s.PadLeft(5, char)

In this case, you don't have to test whether to add 1, 2 or 3 zeros, it'll automatically add the number of zeros needed to make it 5 digits number.

Answer 2

int input_number = Convert.ToInt32(txtinput.Text);
string number_value = input_number.ToString("00000");

I hope that it will solve your problem. It worked well for me in my previous project. Test this code in your development. It should be worked properly without doubt.

Answer 3

You should use the ToString() method with custom formating - see the docs. In particular the 0 specifier.

Replaces the zero with the corresponding digit if one is present; otherwise, zero appears in the result string.

eg,

value = number.Tostring("00000");
