wpf - What is the proper way to set up a domain class MongoDB/C# -

I am currently creating a WPF application and am now ready to add a mango database, although I do not know I found this to be the best process to do with this:

MongoManagment.cs:

  Namesplace MoneyManagment {class MongoManagment {Public Zero Connect () {String connection string = "mongodb: // local host"; MongoClient Client = new Mongo Client (connectionString); MongoServer Server = client.GetServer (); MongoDatabase database = server.GetDatabase ("MoneyManagment"); // Connect to Database MongoCollection & lt; Users & gt; _users = database.GetCollection & lt; Users & gt; ("the user"); // "user" is the collection name, "user" is the domain class}} public class user {public object id _id {get; Set; } Public String Username {get; Set; }}}  

Then I try to access the domain class data in menundo.xcls:

  Namesplace MoneyManagment {Public partial square MainWindow: Window {public manwindows () {initialization (); Foreach (user user in _users.FindAll) () do something with the user here}}}  

And I get an error here that VS _users , which Somewhat understandable, the problem is that, I have tried many different ways to make this accessible and it just is not working, which makes me believe that to know about it There is a better way. Any ideas?

First of all, you need a variable that you want to access to appear publicly Are there.

  Public Square MongoManagment {Public MongoCollection & lt; Users & gt; Mongoowers {receive; Set;} Public Zero Connect () {.... this.MongoUsers = database.GetCollection & lt; Users & gt; ("the user"); }  

After that, you need to reference the object in the external class:

  public manwindows () {.... MongoManagement mm = new MongoManagement (); Mm.Connect ();  

Note This is a very simple example, for example, if you do not do anything with user data in Foreach (user user mm.MongoUsers.FindAll ()) And you do not want a copy of the Mongo management for every window, etc. Still, you want to spend some time exploring the concepts of variable lifestyles ....
