翻译FilterDefinition＆LT; TDocument＆GT;定期JSON蒙戈查询，我可以在蒙戈shell中运行 [英] Translate FilterDefinition<TDocument> to regular json mongo query that i can run in a mongo shell

问题描述

我有很多复杂的查询，我有时想直接核对蒙戈调试\解释（）的目的。 随着新2.0+ C＃的驱动程序，我不知道如何做到这一点。随着previous版本有一个东西叫; IMongoQuery;和这的工作。

I have many complex queries that I sometimes wish to check directly against Mongo for debugging \ explaining() purposes. With the newer 2.0+ c# driver, i'm not sure how to do this. With the previous version there was a thing called ;IMongoQuery; and This worked.

一个简单的例子：

FilterDefinition<LalalaEvent> filter = Builders<LalalaEvent>.Filter.Where(e=> ids.Contains(e.Id) && e.Deleted != true );

感谢。

推荐答案

如果您使用的驱动程序，这是最新的2.0.1版，你可以很容易地把该过滤器在查找运行，返回一个 IFindFluent 并打印其的ToString ：

If you're using the latest version of the driver, which is 2.0.1 you can easily put that filter in a Find operation, get back an IFindFluent and print its ToString:

var filter = Builders<LalalaEvent>.Filter.Where(e => ids.Contains(e.Id) && e.Deleted != true);
var findFluent = collection.Find(filter);
Console.WriteLine(findFluent);

例如对于我这种打印：

find({ "_id" : { "$in" : [1, 2, 3] }, "Deleted" : { "$ne" : true } })
