Hello,
So I'm doing some mathematical modeling and it turns out I need
distinct imaginary and complex types to carry out complex contour
integration.
I want to have it in all three precisions (float, double, and decimal),
and the code is highly redundant, but I can't seem to come up with a
clean way to use Generics in the code. For example, the following
doesn't work
public struct Imag<Twhere T:System.ValueT ype
{
T imag;
public static Imag<Toperator +(Imag<Ta, Imag<Tb) { //implmentation}
public static Imag<Toperator -(Imag<Ta, Imag<Tb) { //implmentation}
public static T operator *(Imag<Ta, Imag<Tb) { //implmentation}
// and so on
}
Basically I need a way to make a Generic struct (can't be a class for
speed) that can only accept floats, doubles and decimals. Is this
possible in the current spec? I tried setting up an interface, but
those do not allow operators.
I really appreciate any help. Thanks.

I don't think there's a way to do what you want, unless the where
clause can support an Or concept..

Well, all the generic is saving you is the trouble of writing three
separate classes. Really, all you're saving here is typing. There
really shouldn't be that much code; just type it out three times.
Generics are really intended for open-ended type creation. In other
words, if you're in the situation in which you say, "I need imaginary
numbers based on floats, doubles, and decimals, but later I might
create another value type and want an imaginary version of _that_,"
then you need a generic solution. If your set of possible type
parameters is closed, and only three, just write the code three times,
as ugly as that may seem, it's simple and easy to maintain. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I've read some material on the upcoming Generics for C#. I've
seen two types of syntax used for constraints:
- direct specification of the interface in the angle brackets
- where clauses
I looked at the files in the Gyro download but I couldn't find any
mention of constraints. Can anyone enlighten me what the current
status is and what we can expect when Generics are released?
Thanks,

In a nutshell, the current .NET generics & .NET framework make it

Why do people spend so much time writing complex generic types?
for fun?
to learn?
for use?
I think of generics like I do about operator overloading.
Great to have as a language-feature, as it defines the language more
completely. Great to use.

Basically I'd like to implement the composite design pattern with leaves that
are either of reference or value types, but even using generics I can't seem
to avoid boxing (using ArrayList or Object)
Is this even possible, or is the composite pattern doomed to use the
System.Object type forever?
I have tried using interfaces with generics, but I always stumble on the
Value property (when trying to return the value of a particular node)
