小编use*_*926的帖子

我使用以下代码来引用shell DLL

            Type t = Type.GetTypeFromProgID("Shell.Application");

            Shell s = (Shell)Activator.CreateInstance(t);


            Console.WriteLine("success");
            Console.ReadLine();

它在我的Windows 7开发机器上工作正常.但是当我尝试在Win 2003服务器上运行exe时,我得到了这个异常

Unable to cast COM object of type 'System.__ComObject' to interface type 'Shell3
2.Shell'. This operation failed because the QueryInterface call on the COM compo
nent for the interface with IID '{866738B9-6CF2-4DE8-8767-F794EBE74F4E}' failed
due to the following error: No such interface supported (Exception from HRESULT:
0x80004002 (E_NOINTERFACE)).

我从C#中获得了一些帮助:引用了一个Windows shell界面,但没有运气.

我使用Microsoft Shell控件和自动化引用引用shell,这是Interop.Shell32 dll

如果有人可以指导,那将非常有帮助.

我想知道LINQ通用集合的方法.

我的客户类是

 class Customer
    {
        public string Name { get; set; }
        public string id { get; set; }
    }

我的收藏课是

class genericCollection<T> : CollectionBase
{
    public void add(T GenericObject)
    {
        this.List.Add(GenericObject);
    }
}

然后我将一些数据添加到客户集合中

  genericCollection<Customer> customers = new genericCollection<Customer>();
  customers.add(new Customer {id= "1",Name="Andy"});

  customers.add(new Customer { id = "2", Name = "MArk" });
  customers.add(new Customer { id = "3", Name = "Jason" });
  customers.add(new Customer { id = "4", Name = "Alex" });

现在我可以使用foreach循环遍历客户对象,但我怎么能知道它.

我想用类似的东西

var query =  from …
