The "0" custom format specifier in C#
The “0” custom specifier is a zero placeholder.
If the value to be formatted has a digit in the position where the zero appears in the format string, the the digit is copied to the resultant string. However, if this doesn’t happen, then a zero appears.
Here is our double variable.
double d; d = 292;
Now, by setting the following, you can easily make zero appear in the format string.
d.ToString("00000")Example
using System;
using System.Globalization;
class Demo {
static void Main() {
double d;
d = 292;
Console.WriteLine(d.ToString("00000"));
Console.WriteLine(String.Format("{0:00000}", d));
d = 3.5;
Console.WriteLine(d.ToString("0.00", CultureInfo.InvariantCulture));
}
}Output
00292 00292 3.50
