    copied!<p>I have some issues resolving an algorithm used to find all posible combinations taking elements from N diferents lists (where N>=2 &amp;&amp; N&lt;=7 -> this number is fixed and I can make a diferent method for each N). The problems goes as this: I have five dictionaries:</p> <pre><code>IDictionary&lt;int, MyEnum&gt; listOne; IDictionary&lt;int, MyEnum&gt; listTwo; IDictionary&lt;int, MyEnum&gt; listThree; IDictionary&lt;int, MyEnum&gt; listFour; IDictionary&lt;int, MyEnum&gt; listN; enum MyEnum { MyEnumOne, MyEnumTwo, MyEnumThree, MyEnumFour, MyEnumFive, MyEnumOther } </code></pre> <p>which can have any number of elements (not more than 100, and most of the time they will have between 32 and 64 elements) and where MyEnum is a simple name enum with some values.</p> <p>For each possible combination, I have some method which examinates the combination and checks if it satisfies some conditions,and if they are satisfied stores some data based on the combination.</p> <p>I have tried simple nested iterations using foreachs for each list, which as expected, take eons to run!</p> <p>Any help, as where I should start, what should I do, or event what I should not do will be more than welcome!, also if more info is needed, please feel free to ask!</p> <p><em>*</em>*EDIT: a combination, based on five lists as shown before would be, for example:</p> <pre><code>(MyEnumOne, MyEnumOne, MyEnumFour, MyEnumFive, MyEnumTwo) </code></pre> <p>and, as this combination, can appear several times (as MyEnumOne value can be many times on listOne, etc), I have to also, keep record of how many times does this combination happens.</p>
