I have several generic lists which have different quantity of properties, but all of them have some
common field names, for instance, id, port, name, and so on.
I have something like snippet.
public bool LookPortName<T>(List<T> list, string id, ref string port, ref string name)
{
int index;
try
{
//It checks if found id into generic list.
if (index == -1) return false;
//Get portfolio abbreviation.
port = list[index].portfolio.Trim();
//Get portfolio complete name.
name = list[index].portName.Trim();
return true;
}
catch
{
//Other code
}
}
Generic list into method
All lists have common files such as “id”, “portfolio” and “portName” but they doesn’t exist into generic
method.
Is it possible to use fields of generic list into generic method?
Someone who knows how to solve my question with a clear code example?
Thanks a lot!

Use a generic interface
// modify interface to fit your program
interface IPortfolio {
public string Id { get; set; }
public string portfolio { get; set; }
public string portName { get; set; }
}
and add where T : IPortfolio to the method declaration
This allows you to use T as if it were an IPortfolio.
public bool LookPortName<T>(List<T> list, string id, ref string port, ref string name) where T : IPortfolio
Then, have any class which needs to be passed into the method implement the interface
Note that you can’t just use an interface because you wouldn’t be able to pass a list.
