我尝试使用数据模型创建视图。将其转换为字符串邮件。当我在localserver上运行它时工作正常但是当上传到azure时崩溃说： [ArgumentNullException：Value不能为null。参数名称：view]
当不再在localserver上运行时，无法弄清楚为什么view为null。
通过弄乱视图的路径，我可以在localserver上获得与azure上的版本相同的错误消息
public static string MailViewToString(ControllerContext context, string viewName, TipsFormModel FormModel)
{
context.Controller.ViewData.Model = FormModel;
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindView(context, viewName, null);
var viewContext = new ViewContext(context, viewResult.View, context.Controller.ViewData, context.Controller.TempData, sw);
viewResult.View.Render(viewContext, sw);
viewResult.ViewEngine.ReleaseView(context, viewResult.View);
return sw.GetStringBuilder().ToString();
}
}
