I am attempting to create a ternary expression and I am getting the following error
"Type of conditional expression cannot be determined because there is no implicit conversion between LiveSubscription and DisconnectedSubscription"
The same logic works in an if statement, but I wanted to understand why it won't work in a ternary expression -
Here is the gist of what I am trying to do:
public interface IClientSubscription
{
bool TryDisconnect();
}
public class LiveSubscription : IClientSubscription
{
public bool TryDisconnect()
{
return true;
}
}
public class DisconnectedSubscription : IClientSubscription
{
public bool TryDisconnect()
{
return true;
}
}
public class ConnectionManager
{
public readonly IClientSubscription Subscription;
public ConnectionManager(bool IsLive)
{
// This throws the exception
Subscription = (IsLive)
? new LiveSubscription()
: new DisconnectedSubscription();
// This works
if (IsLive)
{
Subscription = new LiveSubscription();
}
else
{
Subscription = new DisconnectedSubscription();
}
}
}
I could always switch it to an if/else but I wanted to understand what is going wrong first!
