C# syntax for array of Queue
I cannot find syntax for arrays of Queue! All variations I have tried
seem to be rejected by the compiler in VS2008.
Perhaps someone can give me an answer to this?
Currently I have made the Queues separate as shown below:
// this form does not seem to accept an argument for initial capacity!
public Queue<double> firstQueue0 = new Queue<double>();
public Queue<double> firstQueue1 = new Queue<double>();
public Queue<double> firstQueue2 = new Queue<double>();
public Queue<double> firstQueue3 = new Queue<double>();
public Queue<double> firstQueue4 = new Queue<double>();
public Queue<double> firstQueue5 = new Queue<double>();
public Queue<double> firstQueue6 = new Queue<double>();
public Queue<double> firstQueue7 = new Queue<double>();
public Queue<double> firstQueue8 = new Queue<double>();
public Queue<double> firstQueue9 = new Queue<double>();
THis works for me but what I would really like is an array.
Also is Queue threadsafe?
And why does Queue<double>() not accept an initial capacity
argument like Queue firstQueue0 = new Queue(100); does?
Thanks!

The Queue constructor with a initial capacity parameter is only available on .NET Framework 4. Prior versions of the framework does not have that option.

OK, I believe wdosanjos gives wrong information. See
http://msdn.microsoft.com/en-us/library/system.collections.queue.queue(v=VS.80).aspx
for the 2.0Queue class:
"Queue (Int32) Initializes a new instance of the Queue class that is empty, has the specified initial capacity, and uses the default growth factor."
About arrays. I believe the asker has VB experience and tried to create an array using "()" brackets instead of "[]". I do this mistake quite often when switching from VB to C#...

@anarki_jimbel, you are right. Sorry, for the misinformation.

Thank you, I am now able to instantiate an array of queues.
Some of my confusion may have been in thinking
I should be able to instantiate the array and
populate it with queue objects in one step/line.
So, the part from @wdosanjos was useful to me.
I would still like to understand why Queue<double>
and Queue come from different places but I did not ask
that specifically I realize.
