How to separate values from form collection object with repeated separator
value in asp.net mvc 1.0

I m stuck with the string split functionality in my own project where the
case scenario is as follows
1 I have a formCollection object values which are passed when we send the
page to server for manipulation purpose,where i have one field which is
decimal with precision of 13 and scale of 2 and i have one java script
function which call on onblur event of textbox which return the Input
values in currency formatted value. for eg "12500" in "12,500.00" or
130000 in "1,30,000.00"
2 But the thing is that i m separating the formCollection values by ','
but in this case it is separating the value like
eg "12,500.00" in "12"
i want the separation from '.00'
My Development Platform is ASP.NET MVC 1.0
Please reply me asap its on urgent basic
