gis - 启动会话编辑时无法编辑要素图层

问题描述

我正在开发一个基于 ArcGIS Engine 的独立应用程序，当我开始使用以下代码块进行会话编辑时：

//Declare the Engine editor at the class level.
private IEngineEditor m_engineEditor = new EngineEditorClass();

private void StartEditing(IMapControl2 m_mapControl)
{
    IMap map = m_mapControl.Map;

    //If an edit session has already been started, exit.
    if (m_engineEditor.EditState != esriEngineEditState.esriEngineStateNotEditing)
        return ;

    //Start editing the workspace of the first feature layer found.
    for (int layerCounter = 0; layerCounter <= map.LayerCount - 1; layerCounter++)
    {
        ILayer currentLayer = map.get_Layer(layerCounter);
        if (currentLayer is IFeatureLayer)
        {
            IFeatureLayer featureLayer = currentLayer as IFeatureLayer;
            IDataset dataset = featureLayer.FeatureClass as IDataset;
            IWorkspace workspace = dataset.Workspace;
            m_engineEditor.StartEditing(workspace, map);
            ((IEngineEditLayers)m_engineEditor).SetTargetLayer(featureLayer);
            break;
        }
    }
}

发生异常，错误代码：HRESULT: 0x80004005 (E_FAIL))。请帮我

解决方案

在询问 Google 并阅读 ArcGIS Engine 文档后。我发现我的 SDE GeoDatabase 不允许编辑数据，因为我关闭了 ArcGIS GeoDatabase 的版本管理器。打开它并添加一些代码来检查要素图层是否可编辑。

IEngineEditLayers m_engineLayersEditor = m_engineEditor as IEngineEditLayers;
if (!m_engineLayersEditor.IsEditable(featureLayer))
{
    MessageBox.Show("Can not start editing. Because feature layer is not allow editing", "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
