ASPNET MVC 生成静态页并显示生成进度
实现思路：
1.后台生成页面后，更新生成进度，写入缓存
2.前台用定时器读取缓存实时进度，更新进度条
页面效果：
MVCHelper.cs
#region 生成静态内容
/// <summary>
/// 生成静态内容
/// </summary>
/// <param name="context"></param>
/// <param name="viewPath"></param>
/// <param name="model"></param>
/// <returns></returns>
public static string RenderViewToString(ControllerContext context,
string viewPath,
object model = null)
{
ViewEngineResult viewEngineResult =
ViewEngines.Engines.FindView(context, viewPath, null);
if (viewEngineResult == null)
throw new FileNotFoundException("View" + viewPath + "cannot be found.");
var view = viewEngineResult.View;
context.Controller.ViewData.Model = model;
using (var sw = new StringWriter())
{
var ctx = new ViewContext(context, view,
context.Controller.ViewData,
context.Controller.TempData,
sw);
view.Render(ctx, sw);
return sw.ToString();
}
}
