在ASP.NET MVC Web应用程序集信息版本控制忽略？ [英] AssemblyInfo versioning ignored in ASP.NET MVC Web App?
问题描述
奇怪的人在这里。根据是什么在的AssemblyInfo.cs 设置我的MVC Web应用程序的版本号是不正确打印我的看法。该定义我的设置设定为的AssemblyInfo.cs 为 1.0.232.0 。
Strange one here. My MVC Web Application's version number is not printing correctly to my view according to what is set in AssemblyInfo.cs. The definition I have set in set AssemblyInfo.cs is '1.0.232.0'.
我试图以打印多种方法：
I have tried multiple methods in order to print it:
<%= System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString()%>
（结果0.0.0.0）
(results 0.0.0.0)
<%= System.Reflection.Assembly.GetCallingAssembly().GetName().Version.ToString()%>
（结果2.0.0.0，这是设置无处在我的项目。）
(results in 2.0.0.0, which is set nowhere in my project.)
<%= typeof(HomeController).GetType().Assembly.GetName().Version.ToString()%>
（结果2.0.0.0）
(results in 2.0.0.0)
这使我相信，那根本不能拿起我的AssemblyInfo.cs文件？这也是这种情况，如果我尝试使用发布按钮发布到我们的IIS开发服务器上。
This leads me to believe that it simply must not be picking up my AssemblyInfo.cs file? This is also the case if I attempt to use the "Publish" button to publish to IIS on our development server.
任何想法？也许我使用错误的语句来获取版本号？ ：\
Any ideas? Perhaps I'm using the wrong statement to fetch the version number? :\
谢谢你们。
推荐答案
的看法是（默认）在很大程度上仍然编译点播，让您可靠续使用 GetExecutingAssembly（）在视图中 - 但是，对我来说，控制器使用正常工作：
The view is (by default) still largely compiled on-demand, so you con't reliably use GetExecutingAssembly() within the view - however, for me the controller usage works fine:
[assembly: AssemblyVersion("1.2.3.4")]
与
<h2><%=typeof(MvcApplication4.Controllers.HomeController).Assembly
.GetName().Version.ToString() %></h2>
节目
1.2.3.4
在页面中。 修改
你犯的错误是调用的typeof（...）的GetType（） - 这是要给你键入 （或子类） - 所以是的，这将是2.x的
/修改
edit
The mistake you made was calling typeof(...).GetType() - that is going to give you Type (or a subclass) - so yes, it will be 2.x.
/edit
有关的额外步骤pre-编译的意见，请参阅MSBuild任务的编译次数<一href="http://weblogs.asp.net/scottgu/archive/2008/12/19/asp-net-mvc-design-gallery-and-upcoming-view-improvements-with-the-asp-net-mvc-release-candidate.aspx"相对=nofollow>这里。
For the extra step of pre-compiling the views, see "MSBuild Task for Compiling Views" here.
可以说，你的看法不应该反正取这个数据本身 - 它应该被放入ViewData的（或类似），或许是一个基控制器或动作过滤
Arguably, your view shouldn't be fetching this data itself anyway - it should be put into the ViewData (or similar), perhaps by a base-controller or action-filter.
再约母版页的问题;第一，选择一个关键;-p
Re the question about master pages; first, pick a key ;-p
<%=ViewData["AppVersion"] %>
然后两个选项飞跃在脑海中：覆盖 OnActionExecuting 控制器（或一个共同的基础控制器）：
then two options leap to mind: override OnActionExecuting in the controller (or a common base-controller):
protected override void OnActionExecuting(
ActionExecutingContext filterContext)
{
filterContext.Controller.ViewData["AppVersion"] =
GetType().Assembly.GetName()
.Version.ToString(); // probably cached
base.OnActionExecuting(filterContext);
}
，或创建一个动作过滤器：
or create an action-filter:
public class AppVersionAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(
ActionExecutingContext filterContext)
{
filterContext.Controller.ViewData["AppVersion"] =
GetType().Assembly.GetName()
.Version.ToString(); // probably cached
base.OnActionExecuting(filterContext);
}
}
和与此属性标记您的控制器（类）或动作（方法）：
And mark your controllers (classes) or actions (methods) with this attribute:
[HandleError, AppVersion]
public class HomeController : Controller
{ ... }
