Question

I have this class:

class A {
    string name;
    string code;
}

Examples:

A1: name="blabla", code="kuku"
A2: name="blabla", code=null
A3: name=null, code="kuku"

Dictionary<A, string> d=new Dictionary<A, string>();

d[A1]="aaa";
d[A2]="bbb"
results: d[A1]="bbb";

d[A1]="aaa";
d[A3]="bbb"
results: d[A1]="bbb";

d[A2]="aaa";
d[A3]="bbb"
results: d[A2]="aaa"; d[A3]="bbb";

Is there a way to implement class A as a Key to dictionary?

To answer your edited question:

Make two different string dictionaries (one for Name and one for Code) and search whichever one you have a value for.
