What I meant of course was:

new Tuple(new object[2] {col, row})

Which, all in all, is marginally slower than the pure Python solution... :-)

:-)

That is probably it.

Thanks

Actually, I don't really have a clue about this but

Tuple key = new Tuple(new object[col, row]);

seems like it doesn't do what it probably should do, or do you intend to
pass a multidimensional array to the Tuple constructor?

[IronPython] Using and IronPython 1.1 Dictionary from C#

2008-04-18 Thread Michael Foord 
Hello all,

I'm trying to use an IronPython (1.1) dictionary from C#, where the 
dictionary is keyed by tuples.

I am printing the keys - so I can see that the values I want are in the 
dictionary, but I can't fetch  them. I have tried various approaches - 
the problem seems to be that when I create a new Tuple from two integers 
it isn't recognised as a valid key. Any suggestions/corrections.

Code below (range is a Python 'Dict'):


System.Console.WriteLine("Keys: {0}", range.keys());
for (int row = minRow; row < (maxRow + 1); row++)
{
for (int col = minCol; col < (maxCol+1); col++)
{
Tuple key = new Tuple(new object[col, row]);
object val = range.GetValue(key);
if (val != null)
{
try
{
result = (Double)FloatOps.Add(result, val);
}
catch (Exception e)
{
System.Console.WriteLine(e);
}
}
else
{
System.Console.WriteLine("No Value for col 
{0} row {1}", col, row);
}
}

I'm aware that the cast there is 'dubious', but as my code never reaches 
it it hasn't been a problem so far!
