can't I use TryGetValue and assign the value to a property?

Question

I'm trying to do

myDic.TryGetValue("username", out user.Username);

but its not working.

is this not possible?

Answer 1

No, from the documentation:

"Properties are not variables and therefore cannot be passed as out parameters."

Answer 2

To continue John's answer, do this instead:

string username;
if (myDic.TryGetValue("username", out username))
{
  user.Username = username;
}
