Question

我从这个网站借用了这段代码 http://forums.arcgis.com/threads/30635-How-to-Select-Feature-by-XY-Location-and-Highlight-it-in-ArcMap-9.3-programmatically

它涉及缩放到mappoint。但我不知道如何实现这一点。或者我需要或使用的参考文献。

因为我是arcgis和c＃的总菜鸟。如果有经验的人可以帮助我非常感谢。

public static void CaptureMapCoordinates(int x, int y)
    {
        // get the map coordinates from the screen coordinates
        IPoint pScreenPoint = new ESRI.ArcGIS.Geometry.Point();
        IPoint pMapPoint = new ESRI.ArcGIS.Geometry.Point();
        IEnvelope pEnv = new EnvelopeClass();

        pScreenPoint.X = x;
        pScreenPoint.Y = y;

        pMapPoint = GetMapCoordinatesFromScreenCoordinates(pScreenPoint, pActiveView);

        pEnv = pActiveView.Extent;
        pEnv.CenterAt(pMapPoint);

        pActiveView.Extent = pEnv;
        pActiveView.Refresh();

    }

    private static IPoint GetMapCoordinatesFromScreenCoordinates(IPoint pScreenPoint, IActiveView pActiveView)
    {
        IScreenDisplay pScreenDisplay;
        IDisplayTransformation pDisplayTransformation;

        if (pScreenPoint == null || pScreenPoint.IsEmpty || pActiveView == null)
        {
            return null;
        }

        pScreenDisplay = pActiveView.ScreenDisplay;
        pDisplayTransformation = pScreenDisplay.DisplayTransformation;

        return pDisplayTransformation.ToMapPoint((int)pScreenPoint.X, (int)pScreenPoint.Y);
    }

我从您的评论中得到了您希望为ArcMap而不是独立的WPF应用添加内容。我相信这个链接会让你开始。这是为ArcMap创建添加项的分步过程

您需要Visual Studio进行开发。

如果有帮助，请将此标记为答案。感谢

arcgis使用参考
