Question

I have a multidimensional list:

    List<string>[] list = new List<string>[2];
    list[0] = new List<string>();
    list[1] = new List<string>();

And I iterate though the list as follows – but this only iterates through one list:

foreach (String str in dbConnectObject.Select()[0])
{
   Console.WriteLine(str);
}

Although I want to be able to do something like:

foreach (String str in dbConnectObject.Select()[0] & String str2 in dbConnectObject.Select()[1])
{
   Console.WriteLine(str + str2);
}

If the lists are of the same size, you can use Enumerable.Zip:

foreach (var p in dbConnectObject.Select()[0].Zip(dbConnectObject.Select()[1], (a,b) => new {First = a, Second = b})) {
    Console.Writeline("{0} {1}", p.First, p.Second);
}
