如何将IEnumerable <T>绑定到C＃中的Crystal Report文档？

Question

我有Crystal Report和Entity Framework的问题。我开发的WinForm应用程序只有一个函数可以从表中获取所有记录，然后将其全部填充到Crystal Report中。

我对CR 2010非常新，我搜索了一段时间，但仍然没有找到解决方案。

让说我有以下各列的表格（客户）：

ID, Name, Buy, Price 

和CR文件：

ID: @ID 
Name: @Name 

Buy   Price 
@Buy   @Price 

       TotalPrice 

我们可不可以客户列表直接绑定到一个CR文件而不将其转换为XML或数据集对象？

任何帮助将不胜感激！
