我想用这样的代码查询数据库

Hi
I am working on project base on Silverlight 5 .
I use data service for connection to sql database.

when i want to query database i must user DataServiceCollection<t> for loading my data into it.
I want to query database with like this code

DataServiceCollection<?anonymousetype?> collection= new DataServiceCollection<?anonymousetype?>();
               collection.LoadAsync( from sContract in _entityService.Entity.SContracts
                       select new
                                   {
                                       ContractID = sContract.ContractID,
                                       SCNTTitle = sContract.SCNTTitle,
                                       ContractNum = sContract.ContractNum,
                                       ContractDate = sContract.ContractDate,
                                       SupervisionName = sContract.User.FirstName + " " + sContract.User.Family,
                                       CompnayName = sContract.Contractors_Counselors.CompanyName,
                                   });

但出现错误

如何查询我的查询返回带有新关键字???的匿名类型的数据库?

非常感谢

but I got error

How can I query database that my Query return a anonymousetype with new keyword ???

thanks a lot

推荐答案

只需使用object作为返回类型.

rviceCollection<object> collection= new DataServiceCollection<object>();</object></object>

Just use object as the return type.

rviceCollection<object> collection= new DataServiceCollection<object>();</object></object>
