[Solved] Format exception is given [closed]

by


Look at the following:

//this variable is for saving results
Dictionary<int,double> memberLengthMap = new Dictionary<int,double>();

Dictionary<int, Tuple<double, double, double>> nodes = GetNodeID_AlongWithCoordinates();
Dictionary<int, Tuple<int,int>> members = GetMemberID_AlongWithStartandEndNode();
foreach(KeyValuePair<int, Tuple<int,int>> member in members)
{
    Tuple<double, double, double> startNode = nodes[member.Value.Item1];
    Tuple<double, double, double> endNode = nodes[member.Value.Item2];
    double xDiff = (startNode.Item1 - endNode.Item1);
    double yDiff = (startNode.Item2 - endNode.Item2);
    double zDiff = (startNode.Item3 - endNode.Item3);

    double distance = Math.Sqrt(xDiff*xDiff + yDiff*yDiff + zDiff*zDiff);
    memberLengthMap.Add(member.Key,distance);
}

I hope that helped
