我正在使用Rob Conery的Massive ORM。

I'm using Rob Conery's Massive ORM.

有没有一种优雅的方法来计算返回的记录集？

Is there an elegant way to do a count on the record set returned?

dynamic viewModelExpando = result.ViewData.Model; var queryFromMassiveDynamic = viewModelExpando.TenTricksNewestFirst; //fails as have actually got TryInvokeMember on it var z = queryFromMassiveDynamic.Count(); //works int i = 0; foreach (var item in queryFromMassiveDynamic) { i++; }

推荐答案

扩展方法成员语法，请尝试直接调用静态方法。

Rather than calling it using the extension method member syntax, try calling the static method directly.

int count = Enumerable.Count(queryFromMassiveDynamic);
