How to retrieve the parameters of a Q# operation? Is it possible to do such a thing at all?
You are assuming a 1-1 mapping from a Q# operation with a C# operation but it doesn't work like that. A Q# operation can have a lot more functionality than a C# class, for example, Q# offers the ability to automatically create the
controlled versions of a the operation.
As Mariia pointed out, https://stackoverflow.com/questions/59022076/how-to-get-the-type-of-a-q-operation-parameter is a very similar question and the same answer applies:
Each Q# operations generations a C# class that extends the generic class
Operation<I,O>, so to figure out what the input/output parameters you can take a look at the
BaseType of the operation's
Type, and look at the value of the
GenericTypeArguments to figure out the input type.
