    findNearbySpec... c# problem

    Code:
    FindResults foundResults;
    foundResults = findService.FindNearby(findNearbySpec);
    ViewByHeightWidth[] views = new ViewByHeightWidth[1];
    views=null;
    views[0] = foundResults.Results[0].FoundLocation.BestMapView.ByHeightWidth;
    I have this exception Object reference not set to an instance of an object.

    I cannot find the problem... There are many places found in foundResults

    can you help me?
    Thank you..

    Hi,

    You set views = null; before you assign something to views[0]. You cannot assign to a null pointer. Probably that's the reasonl.

    Somtthing like this is better I think:

    Code:
    FindResults foundResults;
    foundResults = findService.FindNearby(findNearbySpec);
    ViewByHeightWidth[] views = new ViewByHeightWidth[1];
    // views=null; in comment
    if (foundResults)
        views[0] = foundResults.Results[0].FoundLocation.BestMapView.ByHeightWidth;
