问题描述
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);
