SPMetal不生成具有适当自定义类型的类。 将所有内容默认为“项目”

Question

I'm trying to generate classes using SPMetal to make use of SPLINQ. Generating the code is no problem, except the properties are not typed properly.

This is fraction of the code:

[Microsoft.SharePoint.Linq.ListAttribute(Name="Actual Purchase Orders")]
public Microsoft.SharePoint.Linq.EntityList<Item> ActualPurchaseOrders {
    get {
        return this.GetList<Item>("Actual Purchase Orders");
    }
}

As you can see the return type is defined as Microsoft.SharePoint.Linq.EntityList<Item> . While I'd like it to be Microsoft.SharePoint.Linq.EntityList<ActualPurchaseOrder> . This is the same case for all lists and all properties for all list. The only properly typed properties are the sharepoint internal ones like Link, Document, HelpFilesDocument, etc.

I checked all list settings, like content types etc. No luck.

Is it just a bug in my 14.0.4763.1000 version?

Any help appreciated. Cheers.

Answer 1

If ActualPurchaseOrder is not a custom contenttype which you have defined, than you will have to override the spmetal tool with a parameters xml file. (http://msdn.microsoft.com/en-us/library/ee535056.aspx)

I think this blogpost will give you some good steps in the right direction: http://socialsp.com/2009/12/11/having-fun-with-the-new-linq-to-sharepoint-on-sharepoint-2010-sp2010/

Answer 2

public Microsoft.SharePoint.Linq.EntityList<*> ActualPurchaseOrders {

* - >应该是目标列表的内容类型，而不是Item是默认的内容类型。
