What you want is mathematically impossible, but maybe you're asking the wrong question. Perhaps you need 'a' to be a collection; that way it can have multiple values. Like so:
| List<int> a = new List<int>(); |
| a.Add(b); |
| a.Add(c); |
| a.Add(d); |
Or you can use a hashtable / dictionary to use a lookup by name:
| int b, c, d; |
| Dictionary<string, int> a = new Dictionary<string, int>(); |
| a["b"] = b; |
| a["c"] = c; |
| a["d"] = d; |
Or maybe what you need is to access b, c and d through a in a type safe manner:
| class A |
| { |
| public int B { get; set; } |
| public int C { get; set; } |
| public int D { get; set; } |
| } |
| |
| A a = new A { B = 1, C = 2, D = 3 }; |
| |
| // Now you can access b, c and d through a. |
| int x = a.B + a.C + a.D; |
I hope this helps.
