blocks|key|275726|text|简而言之:是的，你可以在RDLC+2008中使用对象数据源(只是不直观而已)。下面是操作步骤：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|275727|打开RDLC页(在“设计”视图中)。稍后，"Data“选项卡将出现在Visual+Studio的顶部。选择“添加新数据源”，选择“对象”，然后选择下一步。从那里，您将能够看到可以绑定到的对象列表。从你的项目中选择你的DTO/业务对象/任何东西并点击Finish。在Visual+Studio左侧的Report+Data侧边栏选项卡中，您将看到对象已添加。复制它生成的数据源名称(类似于"MyProject_MyObject")。|275728|现在，在您的控制器中，您可以提取DTO/BusinessObject的IEnumerable，并将其作为数据参数和您的数据源名称传递，如下所示(对不起，没有VB语法)：|275729|ReportDataSource+reportDataSource+=

The short answer: Yes you can use object data sources in RDLC 2008 (it's just not intuitive). Here's how:

Open your RDLC page (in [Design] view). After a moment, the "Data" tab will appear at the top of Visual Studio. Select "Add New Data Source", choose "Object", and Next. From there, you will be able to see the list of objects you can bind to. Pick your DTO/Business Object/whatever from your project and hit Finish. In the Report Data sidebar tab on the left side of Visual Studio, you will see your object added. Copy the datasource name it generated (it'll be something like "MyProject_MyObject").

Now in your controller, you can pull an IEnumerable of that DTO/BusinessObject and pass it in as the data parameter and your datasource name like this (sorry, no VB syntax):

<pre><code>ReportDataSource reportDataSource =
 new ReportDataSource("MyProject_MyObject", myIEnumerable);
</code></pre>

blocks|key|3187560|text|我不确定你是否看到了我所看到的，但在我看来，具有私有构造函数的类(即使是返回同一类的列表的公共静态方法)也不会出现在列表中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3187561|Criteria+for+object+datasources+to+display+in+Visual+Studio+Report+New+DataSet?|offset|length|3187562|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/7459529/criteria-for-object-datasources-to-display-in-visual-studio-report-new-dataset^0|0|0|27|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I'm not sure if you're seeing what I'm seeing, but it looks to me that classes with private constructors (even with public static methods which return lists of the same class), don't show up in the list.

I had the same problem, but then move the report and the entities classes to another project separate from the WebAplication, when I did that, the wizard show another options other than DataBase Connection, so I add an Object DataSource to the C# Library. Then I use <a href="https://stackoverflow.com/questions/253735/display-rdlc-report-embedded-in-a-dll-file">this post</a> to retrieve the report definition and embedded to the .aspx, hope this help!!

I've created more projects using ReportViewer 2005 and 2008 in local processing mode than I can count on my hands. All Visual Studio 2005 or 2008 ASP.NET web forms projects. I always used some flavor of Object data source for the reports.

Tonight, I attempted to add the same functionality to a Visual Studio 2010 MVC 2 project and am failing miserably. First, the Add New Item > Reporting > Report is now a 2008 RDLC and not a 2005 RDLC report. Secondly, when trying to add a DataSet, my usual method of create a data proxy class with static methods that return <code>IEnumerables(Of Stuff)</code> will not show up as sources in the DataSources drop down

<img src="https://i.stack.imgur.com/0fLnN.png" alt="Empty Data Source">

Thirdly, my only option is to add a Database connection. There is no "Object Data Source" to pick from:

<img src="https://i.stack.imgur.com/7cptm.png" alt="Database connections only">

I'm stumped. Like I kind of alluded to, I have no problems whatsoever actually rendering a report using the ReportViewer control. What I can't do is figure out how set up a Data Source in these new-fangled 2008 reports with Visual Studio 2010 so that I can pump a list of domain objects into the ReportViewer and display the report.

UPDATE

With some more research, I've found that MVC projects do not allow object data sources to be used within them. One solution for my issue is to create a separate project in the solution -- a web application, a service, or even just a class library, to add the report to and design it accordingly.

I'm still looking for alternatives here.

我在本地处理模式下使用ReportViewer 2005和2008创建了更多的项目，我的手已经数不过来了。所有Visual Studio2005或2008 ASP.NET web窗体项目。我总是在报告中使用某种风格的对象数据源。今晚，我试图在一个Visual Studio2010MVC2项目中添加同样的功能，但失败得很...
