C# Padding Amount With Zeros

问题

I have an amount field which is a decimal in the database. I need to always display this amount with 10 numbers on the left of the decimal and two after.

Example:
Amount = 245.00 which should display as 0000000245.00 Additionally, the amount could be over 1,000 or 10,000 which should display as:

0000001245.00 and 0000011245.00

How can I format the amount to always have the appropriate number of zeros on the left side of the decimal with a variable amount size?

回答1:

You should put 0's in your format string. Something like this.

myValue.ToString("0000000000.00");

That will always give you 10 digits on the left side of your decimal point and two on the right.

If you do not want two digits on the right side... do this.

myValue.ToString("0000000000.##");

This says hey if we have a value display it; otherwise, skip it.

This should help... http://www.csharp-examples.net/string-format-int/

So you can use this

string.Format("{0:0000000000.00}", 15.25); // "0000000015.25"

回答3:

yourDecimalVariable.ToString("0000000000.00") should do the trick.
