在OData URI中使用过滤器时出错500

Question

当我使用简单的API时：/api/dashboard它完美无缺！

但是，我添加的任何过滤器都会返回以下错误！

API URI

/api/dashboard?$filter=(ProximoAtendimento%20gt%20datetime'2012-11-30'%20and%20ProximoAtendimento%20lt%20datetime'2012-12-02')

错误

API控制器

[Queryable]
public IQueryable<Pessoa> get()
{
    return _repository.Query<Pessoa>();
}

Answer 1

MissingMethodExceptions通常是由不匹配的程序集版本引起的。在您的情况下，看起来您应该使用此NuGet包：

5.1.0.51016-rc2 for Microsoft.Data.OData.Contrib而不是5.1.0.51119。
