首先，我解决的问题是当视图切换到LayoutView如何把Arcgis中DataFrame的宽度和高度修改了

解决方法

IMapDocument pMapDocument = new MapDocument();

pMapDocument.Open(“mxd路径”);//打开你要修改的MXD文件

IMap pMap = pMapDocument.get_Map(0);

IGraphicsContainer gc = pMapDocument.PageLayout as IGraphicsContainer;

IMapFrame mf = gc.FindFrame(pMap) as IMapFrame;//获取到MapFrame

IElement pElement;

IEnvelope pEnvelope = new Envelope() as IEnvelope;

pEnvelope.PutCoords(0, 0, 21, 29.7);//这里宽度高度 自己决定

pElement = mf as IElement;

pElement.Geometry = pEnvelope;

pMapDocument.ActiveView.Refresh();

pMapDocument.Save();
