Conditional assignment in if clause

I have a code which I do not want to duplicate too much, it looks something like this:

myEnum setting;

if (((input == "Enum0") && ((setting = myEnum_0) == setting)) ||
    ((input == "Enum1") && ((setting = myEnum_1) == setting)) ||
    ((input == "Enum2") && ((setting = myEnum_2) == setting)))
{
    doActionWith(setting);
}

This way I don't have to check if the input was something totally different (if I just assigned with

if (input=="Enum0")
    setting = myEnum_0;

the code wouldn't know if the enum was actually set, or not.

Now I wonder, is there a more elegant solution for the thing at the end?

The && ((setting = myEnum_x) == setting) ?
