Using in Razor VB.net MVC not work as expected

问题:

I'm not sure why this syntax complain error "Enter is not declared. May be inaccessible due to protection level" and must put "@html(" to get rid the error.

This block complain error

   @Using (Html.BeginForm("GetUser", "UserProfile", FormMethod.Post))
      Enter User id :-  @Html.TextBox("UserId",Model)  -- This line must write in this way @Html("Enter User id :-")
      <input type="submit" value="Submit  data" />  --This line complain ">" expected"
   End Using 

If rewrite the code in this way, the complain gone, but the output display "System.Web.MVC.Html" at the beginning like the image below

       @Html.BeginForm("GetUser", "UserProfile", FormMethod.Post)
       Enter User id :-   @Html.TextBox("UserId",Model) 

    <input type="submit" value="Submit  data" />

hi nemesv if Use @<Text>
,it's complain this -->"Using must end with End Using."

When you are inside a Using block you are in "code mode" in Razor.

So you need to use the @: (for single line statements) or @<text> .. </text> (for multi line statements) to switch back to "text mode" and output html.

With using @::

@Using (Html.BeginForm("GetUser", "UserProfile", FormMethod.Post))
      @:Enter User id :-  @Html.TextBox("UserId",Model)  
      @:<input type="submit" value="Submit  data" />
End Using

or with using @<text>:

@Using (Html.BeginForm("GetUser", "UserProfile", FormMethod.Post))
      @<text>Enter User id :-</text>  @Html.TextBox("UserId",Model)  
      @<text><input type="submit" value="Submit  data" /></text>
End Using
