c# - 转换来自不同 namespace 的相同对象？

Question

这些是错误:

Error   1   Cannot implicitly convert type 'Plantool.xRoute.Point' to 'Plantool.xMap.Point' 
Error   2   Cannot implicitly convert type 'Plantool.xRoute.Point' to 'Plantool.xMap.Point' 
Error   3   Cannot implicitly convert type 'Plantool.xRoute.LineString' to 'Plantool.xMap.LineString'

我有这个带有命名空间的代码。

using Plantool; //Contains xMap, xServer, xLocate

这就是有问题的功能。

    /* createMap()
     * Input: WaypointDesc[], Route
     * Output: string mapURL
     * Edited 21/12/12 - Davide Nguyen
     */
    private static string createMap(xRoute.WaypointDesc[] waypointDesc, xRoute.Route route)
    {
        #region boundingBox
        // Set boundingBox fand use corners from the calculated route
        xMap.BoundingBox boundingBox = new xMap.BoundingBox();
        boundingBox.leftTop = route.totalRectangle.rightTop;
        boundingBox.rightBottom = route.totalRectangle.leftBottom;
        #endregion

        #region mapParams
        // Build mapParams
        xMap.MapParams mapParams = new xMap.MapParams();
        mapParams.showScale = true;
        mapParams.useMiles = false;
        #endregion

        #region imageInfo
        // Create imageInfo and set the frame size and image format. NOTE: 1052; 863
        xMap.ImageInfo imageInfo = new xMap.ImageInfo();
        imageInfo.format = xMap.ImageFileFormat.PNG;
        imageInfo.height = 1052;
        imageInfo.width = 863;
        imageInfo.imageParameter = "";
        #endregion

        #region layers
        // Create a line from the calculated route
        xMap.LineString[] lineStrings = new xMap.LineString[] { route.polygon };
        xMap.Lines[] lines = new xMap.Lines[1];
        xMap.LineOptions options = new xMap.LineOptions();
        xMap.LinePartOptions partoptions = new xMap.LinePartOptions();
        partoptions.color = new xMap.Color();
        partoptions.visible = true;
        partoptions.width = -10;
        options.mainLine = partoptions;

        lines[0] = new xMap.Lines();
        lines[0].wrappedLines = lineStrings;
        lines[0].options = options;

        // Define customLayer that contains the object lines and set layers.
        xMap.CustomLayer customLayer = new xMap.CustomLayer();
        customLayer.visible = true;
        customLayer.drawPriority = 100;
        customLayer.wrappedLines = lines;
        customLayer.objectInfos = xMap.ObjectInfoType.NONE;
        customLayer.centerObjects = true;
        xMap.Layer[] layers = new xMap.Layer[] { customLayer };
        #endregion

        #region includeImageInResponse
        // Set argument includeImageInResponse to false (default).
        Boolean includeImageInResponse = false;
        #endregion

        // Return object map using the following method.
        xMap.Map map = xMapClient.renderMapBoundingBox(boundingBox, mapParams, imageInfo, layers, includeImageInResponse, null);

        // Retrieve the image
        string result = "http://" + map.image.url;

        // Return the drawn map
        return result;
    }

问题在于 boundingBox 对象和 lineString 对象。 route.totalRectangle 包含来自 xRoute 命名空间的 Point 对象，它与 xMap 的相同。无论如何复制或转换它？

这个问题在 java 示例中似乎不会发生，但在 C# 中会发生。我相信，如果我能解决这个错误，其他错误也会得到解决。我已经在 API 上搜索了我的屁股，但它可能对你有帮助:

• x map : http://xserver.ptvgroup.com/fileadmin/files/PTV-COMPONENTS/DeveloperZone/Documents/PTV_xServer/API/xMapAPI/pages/apidoc.html
• xRoute:http://xserver.ptvgroup.com/fileadmin/files/PTV-COMPONENTS/DeveloperZone/Documents/PTV_xServer/API/xRouteAPI/pages/apidoc.html

仍在挖掘自己。

Answer 1

在 C# 中，您不能从一种类型转换为另一种类型，即使它们在所有目的上都是相同的，除非复制所有属性等，除非 implicit。转换存在。

因此您可以编写一个隐式转换运算符，如上面的链接所示，或者您可以使用像 AutoMapper 这样的工具在两个对象之间复制
