//只用前五行,可以直接将选中的面要素的颜色全部修改成红色,也就是填充颜色 IRgbColor pRgbColor= new RgbColor();; pRgbColor.Red = 255; pRgbColor.Green = 0; pRgbColor.Blue = 0; IFeatureSelection pFtSelection = pFeatureLayer as IFeatureSelection; //符号边线颜色 ,下边这五行设定选中面的边线,但是需要配合后边的代码执行 IRgbColor pLineColor = new RgbColor(); pLineColor.Red = 255; ILineSymbol ilSymbl = new SimpleLineSymbolClass(); ilSymbl.Color = pLineColor; ilSymbl.Width = 3; //定义选中要素的符号为红色,这部分的作用并没有搞清楚,随后可能还需要研究 ISimpleFillSymbol ipSimpleFillSymbol = new SimpleFillSymbol(); ipSimpleFillSymbol.Outline = ilSymbl; RgbColor pFillColor = new RgbColor(); pFillColor.Green = 60; ipSimpleFillSymbol.Color = pFillColor; ipSimpleFillSymbol.Style = esriSimpleFillStyle.esriSFSNull;//设置成填充效果为空,也就是不填充,有很多填充效果,这是个枚举 //ipSimpleFillSymbol.Style = esriSimpleFillStyle.esriSFSForwardDiagonal; //选取要素集 ,这里需要把pFeatureLayer 转换成IFeatureSelection IFeatureSelection pFtSelection = pFeatureLayer as IFeatureSelection; pFtSelection.SetSelectionSymbol = true; pFtSelection.SelectionSymbol = (ISymbol)ipSimpleFillSymbol;
arcengine的开发真是难入门,所以这里赶紧记下来,当然这里的代码是通过网上搜索的代码又修改的,记录下,自己可以用,别人也可以用
