string-formatting

I am trying to format currency that will always contain 2 decimal digits, but if there are extra digits of accuracy to display up to five. As an example:

for value = 5.0
display: $5.00

for value = 5.023
display: $5.023

for value = 5.333333333333333
display: $5.33333

I have been playing with the .ToString() formatting, but I can't seem to find the right match of options.

Clarification: I want to show from 2-5 decimals, truncating zeros after the second digit.

for value = 5.000000000000000
display: $5.00

for value = 5.333333333333333
display: $5.33333

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
