Hello warmlyyours,

think the problem is in the first part assuming price is a double or at least a non string convert that to string first

string str_price=price.toString;
str_price=String.Format("{0:f}", str_price);

for more on the string.format you could look at
source: http://idunno.org/displayBlog.aspx/2004071401

hope this helps a bit

should be string str_price=price.ToString();

 

by: warmlyyoursPosted on 2005-11-22 at 22:18:40ID: 15348128

actually price is a double and string.Format accepts doubles

so the question still remains, how to apply both formatings...

i have a price double and I want this variable to be outputed in a text email with two zeros after the point, that is what {0:f} does, then I want to allign this variable to the left in a column and that is what {1,10 } does.

I have the following text

Part#:      Description                                                           Price (USD)
----------------------------------------------------------------------------------------------------
60-15B-120T       Roll 15W / 1.5 x 60/11.25amps                                         $903.00

                              -----------------------------------
                              Total                      $1132.75

I want this to be like: (notice the money column)

Part#:      Description                                                           Price (USD)
----------------------------------------------------------------------------------------------------
60-15B-120T       Roll 15W / 1.5 x 60/11.25amps                                           $903.00

                              Subtotal:                  $1052.00

                              -----------------------------------
                              Total                        $1132.75

I want the money column to be aligned to the left and have the two zeros displayed after the point.

hi,

string str_price=String.Format("{1,10}", price);

if im not mistaken this formatting is using the {n,w} format where n is parameter index and w is the width..

it could be {0,10} instead of {1,10} since you only have one parameter "price"

can you please try this instead
------------------------------------------------------
string str_price=String.Format("{0,10}", price);
------------------------------------------------------

hope it helps

 

by: steelheart38Posted on 2005-11-23 at 07:42:33ID: 15350845

also, most of the time, i use to achieve the same results using a single formatting (currency, two decimal places and align right)

to align left just use a negative number instead like {0,-10:C2}

and you might want to use the same formatting
---------------------------------------
String.Format("{0,10:C2}", price)
---------------------------------------

hope it works and helps
