Hi everybody

I have this queue:

Queue<<string>> q1;

1.Is there any way that I make a q to avoid repeated elements when enqueing to it?
Can I set a special q1 property or sth?

2. If I dont do number 1, How can I omit the repeated elements from it
(if any)and update the q?

btw I couldnt use distinct() method because Im not familiar with this "IEnumerable".

Solution 1

Don't worry IEnumerable<> is just a Type, To which you can easily fetch element by element using foreach.

If you don't want to get a distinct result in IEnumerable then you can fetch it in anonymous variable and then iterate that using foreach like

var result = queue.Distinct(); 
foreach(string s in result)
{
}

Or Either way you want in List<String> then you can do following.

List<String> list = queue.Distinct().ToList<String>();

Correct - my 5.
Additionally, it should be noted that IEnumerable is supported anyway:

foreach(string s in queue) { /* use s */ }

Of course, it iterates all items. Not just distinct.

Also, this form of Distinct is for default comparison (how = is defined)
Use Distinct<t>(IEqualityComparer<t>) for custom.
