ArcEngine出图|相关代码

①数据源修复

IMapDocument mapDoc = new MapDocumentClass();
mapDoc.Open(mxdPath);
IDataSourceHelperMapDocument helpler = new DataSourceHelperClass();
helpler.FindAndReplaceWorkspaceNamePath(mapDoc, oldpath, mdbPath, true);
//oldpath为打开的mxd模板中加载的层的路径(任意一个)
//mdbPath为新的对应数据的路径

②修改出图过程中的IElement

            IMapDocument pDoc = new MapDocumentClass();
            pDoc.Open("D:/Desktop/EXPT.mxd");

            IPageLayout pageLayout = pDoc.PageLayout;
            IGraphicsContainer container = pageLayout as IGraphicsContainer;
            container.Reset();

            IElement ele = null;
            while ((ele=container.Next())!=null)
            {
                IElementProperties eleProp = ele as IElementProperties;

                if (ele is ITextElement)
                {
                    switch (eleProp.Name)
                    {
                        case "TITLE":
                            (ele as ITextElement).Text = "Element_TITLE内容更换测试";
                            break;
                        case "LABEL":
                            (ele as ITextElement).Text = "Element_LABEL内容更换测试";
                            break;
                        case "DATE":
                            (ele as ITextElement).Text = "二零二二年四月";
                            break;
                        default:
                            break;
                    }
                    
                }
                else if (ele is IGraphicElement)
                {

                }
            }

③添加辅助图层，并至于对应位置

            IMapDocument pDoc = new MapDocumentClass();
            pDoc.Open("D:/Desktop/EXPT.mxd");

            IWorkspaceFactory pWSF = new ShapefileWorkspaceFactoryClass();
            IFeatureWorkspace pFW = pWSF.OpenFromFile(@"F:\0505\1矢量数据", 0) as IFeatureWorkspace;
            IFeatureLayer pFLayer = new FeatureLayerClass();
            pFLayer.FeatureClass = pFW.OpenFeatureClass("610330JSYDGZQ");

            pDoc.ActiveView.FocusMap.AddLayer(pFLayer);
            pDoc.ActiveView.FocusMap.MoveLayer(pFLayer, 1);
