给出格式异常

本文关键字：异常 格式 | 更新日期: 2023-09-27 18:17:43

输入字符串格式不正确。

public List<int> GetNodeIDInfo()
{
    nodeData_List = this.GetNodeInfo();
    for(int iNode = 0; iNode<nodeData_List.Count; iNode++)
    {
        string[] str = nodeData_List.ElementAt(0);
        foreach (string s in str)
        {
            nodeID_List.Add(Convert.ToInt32(s));
        }
    }
    return nodeID_List;
}

这有什么不对?

给出格式异常

看以下内容:

//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);
}

希望对你有所帮助
