compare a item in a collection

[Josch]

I want to compare a string item in a collection with another string variable. I use collection.items.contains(string_var) to compare if the string_var is in the collection. But i need to compare case insensitive !! How can i do this ?

Can you post some more code?

Anyway what kind of objects are in the collection? You can use a for each loop and compare.

Did you try that?

The collection contains only string items. I know that i can use a for each loop, but is there no other way ?. As long as i have the items.contains function in a collection i really would like to use it.

Example:

dim coll as new collection
 
coll.items.add("Part1")
coll.items.add("PaRt2")
coll.items.add("pArt3")
 
dim something as string = "part2"
 
if coll.items.contains(something) then messagebox.show("Found it")

I hope this helps

I dont know what else to tell you, but if that is not working use the for each loop instead.

In the for each loop you can assign a string variable each string in the collection, convert it to upper or lower case, convert the variable you are comparing then compare the results.

Hope that helped.

I know that, but i am trying to find a more elegant way.

the compare method of the string object takes 3 parameters the first 2 are strings to compare, and the third is a boolean to see if you want to ignore case. It returns an integer that I guess represents if they match or not. Try using that.
