I want to use a foreach loop on two different lists.

I currently have:

foreach (Buyer buyer in buyers)

I would like to add "and foreach Seller seller in sellers" to have it all in the same loop. I have tried simply adding the code with the & sign but that does not work. Any help? I'm sure it is quite simple to do.

Thanks

you have posted this in the c++ forums. I believe you have the wrong place

That looks like C#, not C++?

EDIT: Ah, you've been posting in the wrong place! We HAVE a C# Forum. I will move your topics there.

C++ (or C) doesn't have a foreach loop. Use a for, while or do-while loop.

Sorry guys I didn't realize I posted in the wrong section. Yes this is c# not c/c++.

I am taking a shot in the dark but why not have it some sort of variable collection instead? You could then assign it to match one of your others before the loop and then go through the new collection, or just have three conditonal loops.

Here is some code to illustrate my first idea but I have no idea if it will actually work as I don't have time to test it.

List<Buyer> b = new List<Buyer>();
List<Seller> s = new List<Seller>();

List<object> LoopList = new List<object>();

if(RadioButtonBuyer.Checked == true)
{
LoopList = b;
}

if(RadioButtonSeller.Checked == true)
{
LoopList = s;
}

foreach (object obj in LoopList)
{
//loop logic here
}

Be that as it may, I think we need more information to help you. You may be going about this the wrong way from the start.

Ok, this is for an e-auctioning system. I'm using this for the user to log in. My idea was to have the 'username' entered by the user compared to each 'username' in the 'buyers' and 'sellers' lists to see if there's a match.

In the code I gave earlier, which may or may not work, change the if statements for some sort of other comparison to your database or where ever you store the login information to get if its the buyer or seller. You might even be able somehow to then use the group in a switch statement to assign the list.
