一、.net core mvc下获得
建立一个帮助类,如下:
using microsoft.aspnetcore.mvc; using microsoft.aspnetcore.mvc.rendering; using microsoft.aspnetcore.mvc.viewengines; using microsoft.aspnetcore.mvc.viewfeatures; using system; using system.collections.generic; using system.io; using system.linq; using system.threading.tasks; namespace netcoreportal.models { public class viewhtmlhelper { public static string converttostring(controller controller, string viewname, object viewmodel, bool ismainpage) { controller.viewdata.model = viewmodel; using (stringwriter sw = new stringwriter()) { iviewengine viewengine = controller.httpcontext.requestservices.getservice(typeof(icompositeviewengine)) as icompositeviewengine; viewengineresult viewengineresult = viewengine.findview(controller.controllercontext, viewname, ismainpage); if (viewengineresult.success) { viewcontext viewcontext = new viewcontext( controller.controllercontext, viewengineresult.view, controller.viewdata, controller.tempdata, sw, new htmlhelperoptions() ); viewengineresult.view.renderasync(viewcontext); return sw.getstringbuilder().tostring(); } else { return $"视图{viewname}不存在"; } } } } }
后台调用方法
public contentresult viewtostringdemo() { string strview = viewhtmlhelper.converttostring(this, "index", "", true); return content(strview); }

二、.net mvc下获得
/// <summary> /// 获得laytreegrid视图的html内容 /// </summary> /// <returns></returns> public contentresult viewtext() { string html = string.empty; iview view = viewengines.engines.findview(this.controllercontext, "laytreegrid", null).view; viewdatadictionary vdd = new viewdatadictionary(); tempdatadictionary tdd = new tempdatadictionary(); using (system.io.stringwriter sw = new system.io.stringwriter()) { viewcontext viewcontext = new viewcontext(this.controllercontext, view, vdd, tdd, sw); viewcontext.view.render(viewcontext, sw); html = sw.tostring(); } return content(html); }
