如何在C＃中获取IMongoCollection中的所有项目？

Question

var users = database.GetCollection<ApplicationUser>("users");

Mongodb.driver 2.0中没有FindAll函数。

Answer 1

您应该找到像users.Find(new BsonDocument()).ToListAsync();

Answer 2

丑陋直白的方法：

await (await users.FindAsync(_ => true)).ToListAsync()

Answer 3

You can use LINQ

var collection = _db.GetCollection("users");
return (from x in collection.AsQueryable()
         select x["something"]).toList();

Or maybe if you are in somewhere near Mongo Driver 2.7 version the below query would compile. (note also that generic parameter of Users is redundant here)

List<string> q2=(from x in collection.AsQueryable<users>() select x.Name).ToList();
