NavisWorks Api 简单使用与Gantt

相信很多朋友在做BIM项目的时候.都有客户会提出项目计划,形象进度 等需求。

那么当前最主要的问题就是计划与BIM模型的关联问题.那么我在项目中是用户用Project软件编辑计划然后手动跟三维模型关联。如果同行有更好的解决办法请告诉我，非常感谢

        //当前选中的模型的名称
        private string _currentSelectionName = string.Empty;
        //当前选中的模型的GUID

        //当前选中的Item
        private GanttItem _currentGanttItem = null;、

Gantt 属性存储是以XML的形式存储

[Serializable]
[XmlRoot("Properties")]
public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable, ISerializable
{
    public SerializableDictionary()
    {

    }

    public XmlSchema GetSchema()

    public void ReadXml(XmlReader reader)
    {
        XmlSerializer xmlSerializer = typeof(TKey).CreateDefaultXmlSerializer();
        XmlSerializer xmlSerializer2 = typeof(TValue).CreateDefaultXmlSerializer();
        bool isEmptyElement = reader.IsEmptyElement;
        reader.Read();
        if (!isEmptyElement)
        {
            while (reader.NodeType != XmlNodeType.EndElement)
            {
                reader.ReadStartElement("item");
                reader.ReadStartElement("key");
                TKey key = (TKey)xmlSerializer.Deserialize(reader);

                TValue value = (TValue)xmlSerializer2.Deserialize(reader);
                reader.ReadEndElement();
                base.Add(key, value);
                reader.ReadEndElement();
                reader.MoveToContent();
            }
            reader.ReadEndElement();
        }
    }

    public void WriteXml(XmlWriter writer)

        foreach (TKey key in base.Keys)

            writer.WriteStartElement("key");
            xmlSerializer.Serialize(writer, key);

            TValue val = base[key];
            xmlSerializer2.Serialize(writer, val);
            writer.WriteEndElement();
            writer.WriteEndElement();
        }
    }
}

public static T FromXmlString<T>(string xml)
{
    if (string.IsNullOrEmpty(xml))
    {
        return default(T);
    }
    using (MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
    {
        return XmlObjectHelpers.FromXmlStream<T>(stream);
    }
}

public static T DeserializeFromXml<T>(this string xml)
{
    return XmlObjectHelpers.FromXmlString<T>(xml);
}　

我用的是NavisWorks SDK 2015. 当然每个版本都不一样。如果有错误的地方请网友指出！
