Hallo,

Hat jemand eine Idee, wie ich ein Array der wie folgt definiert wurde:

object [,] dataObj;
DataObj = new object[5,3];

q    w    2
w    z     5
w    z    4
m    d     2
q    w    4

performant gruppieren und summieren kann, so dass ich als Ergebnis

q    w    6
w    z    9
m    d    2

bekomme?
Grüsse
Mark

Create a key from the two first values and use that to put the third
value in a dictionary. If the key already exists in the dictionary, add
the value instead.
