cs动态插入一段html代码,c# mvc 在控制器中动态解析cshtml文件并获取对应的html代码...

public static string GetViewHtml(ControllerContext context, string viewName, Object param)

{

if (string.IsNullOrEmpty(viewName))

viewName = context.RouteData.GetRequiredString("action");

//context.Controller.ViewData.Model = param;

using (var sw = new StringWriter())

{

ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(context, viewName);

var viewContext = new ViewContext(context,

viewResult.View,

context.Controller.ViewData,

context.Controller.TempData,

sw);

try

{

viewResult.View.Render(viewContext, sw);

}

catch (Exception ex)

{

throw;

}

return sw.GetStringBuilder().ToString();

}

}

调用如下

public ActionResult A1(){

ViewData["a"]=1;

retrun View();

}

public ActionResult A2(){

ViewData["a"]=1;//这里也要有ViewData，不然报错

var html=GetViewHtml(this.ControllerContext, "A1", null);

}
