indexers

[John Salerno]

If you create a class with an indexer, can you create it so that the
indexer is more than just a single integer? Something like [][][,] instead?

John,

If you create a class with an indexer, can you create it so that the
indexer is more than just a single integer? Something like [][][,]
instead?

Here is an example of what you are looking for:

which I hope helps.

using System;
class Grid
{
const int NumRows = 26;
const int NumCols = 10;
int[,] cells = new int[NumRows, NumCols];
public int this[char c, int col] {
get {
c = Char.ToUpper(c);
if (c < 'A' || c > 'Z') {
throw new ArgumentException();
}
if (col < 0 || col >= NumCols) {
throw new IndexOutOfRangeException();
}
return cells[c - 'A', col];
}
set {
c = Char.ToUpper(c);
if (c < 'A' || c > 'Z') {
throw new ArgumentException();
}
if (col < 0 || col >= NumCols) {
throw new IndexOutOfRangeException();
}
cells[c - 'A', col] = value;
}
}
