Asp.net web api WebAPI、oData和RavenDb-为$top和$skip抛出错误

我正在使用WebAPI从RavenDb返回基本供应商对象的集合

供应商类别为：

public class Supplier
{
    public string Id { get; set; }
    public string Title { get; set; }
}

WebAPI方法是：

[Queryable]
public IQueryable<Supplier> Get()
{
    using (var session = _store.OpenSession())
    {
        return session.Query<Supplier>();
    }
}

我能够重新编写您的问题，并成功地验证了我对可能出现错误的初步猜测。尝试

[Queryable（EnableConstantParameterization=false）]

而不是普通的

[Queryable]

。在OData开发周期的后期，我们做了一个perf更改，以最佳利用我们默认启用它，因为这是一个安全的更改。不幸的是，我认为RavenDB LINQ提供者无法理解使用此优化生成的LINQ查询。我共享的代码将其关闭并生成普通的LINQ查询。

您可以共享堆栈跟踪吗？我已将堆栈跟踪附加到问题good catch。此外，您可能需要设置

HandleNullPropagation

false。看见
