Accessing-parameters-by-reference-vs-index

Most of the example code i have seen does something like this:

CODE:
AddParameter(...)
...
int foo = Parameters[0].AsInt;

However, accessing parameters by index is error prone, as you have to keep track of the index used if you add more parameters or change the order.

Is it possible to do something like this instead?

CODE:
Parameter myParam = AddParameter(...)
...
int foo = myParam.AsInt;

I tried this and while it compiles fine, the value of foo in this example is not as expected. Using Parameters[index] works as expected.
