Property name MiscalculationSometimes we have to make the HTML content with the Razor statement immediately, eg: Hello, Mr. A. Suppose the variable name is viewbag.name, hello, @ViewBag. Name//So the output is only "Hello," and the latter name is treated as a ViewBag attribute went, so if you want to solve this problem is Add a parenthesisGood, such as "Hello, (@ViewBag. Name)" and one more way Wrap it up with an HTML tag, such as "Hello,< tags > @ViewBag. name</tag > sir", or to wrap it up with HTML tags. Unexpected extra attributesIf you want to output a C # namespace, and the output part of the north wing to become a razor variable, the category is System.Web.Mvc.Controller eg:@{viewbag.mvcnamespace= "SYSTEM.WEB.MVC";} Class is @viewbag.mvcnamespace.controller the result output throws an error, and the string does not contain the controller definition because razor resolves @ When viewbag.mvcnamespace the controller as a controller property of the @viewbag.mvcnamespace, parsing the error, the solution to this situation is to add a parenthesis,Eg: @ (viewbag.mvcnamespace).
