#MongoDB GenericDao ###C# implementation to GenericDao pattern using MongoDB Driver and Linq support

##What methods are supported?

• T GetByID(ID id);
• IEnumerable GetAll();
• T GetByCondition(System.Linq.Expressions.Expression<Func<T, bool>> condition);
• IEnumerable GetAll(System.Linq.Expressions.Expression<Func<T, bool>> condition);
• IEnumerable GetAll(System.Linq.Expressions.Expression<Func<T, bool>> condition, int maxresult, bool orderByDescending);
• T Save(T pobject);
• void Delete(T pobject);
• long Count();
• long Count(System.Linq.Expressions.Expression<Func<T, bool>> condition);
• IEnumerable Paginate(System.Linq.Expressions.Expression<Func<T, bool>> condition, int pagesize, int page, Func<T, TKey> pOrderByClause = null, bool pOrderByDescending = false);
• IEnumerable Paginate(int pagesize, int page, Func<T, TKey> pOrderByClause = null, bool pOrderByDescending = false);
• IEnumerable Search(string field, string search, int page, int pagesize, out long foundedRecords); #Install nuget package

PM> Install-Package MongoDB-GenericDao

#How to use? Each class must have an inheritance from MongoDBGenericDao.MongoDBEntity class

##Create a class

public class Message : MongoDBEntity
{
    public DateTime DateCreated { get; set; }
    public string From { get; set; }
    public List<string> To { get; set; }
    public string Content { get; set; }
}

##Create a business class

public interface IBMessage : IDao<Message, string>
{
	Message AddNewMessage(string from, List<string> to, string messagetext);
}

public class BMessage : MongoDBGenericDao<Message>, IBMessage
{
    public BMessage(string mongodbconnectionstring) : base(mongodbconnectionstring) { }

    public Message AddNewMessage(string from, List<string> to, string messagetext)
    {
    	if(to == null || to.Count == 0)
            throw new ApplicationException("'to' cannot be empty");

    	var message = new Message
    		{
    			DateCreated = DateTime.Now.ToUniversalTime(), //ToUniversalTime() provides datetime serialization
    			From = from,
    			To = to
    		};

    	return this.Save(message); //saves in mongodb and return updated reference
    }
}

##Usage

IBMessage bmessage = new BMessage("[your connectionstring here. ex: server=appserver-db;database=mymongodbdatabasename]");

var message = bmessage.AddNewMessage(	"mongodb@mongodb.com",
										new List<string>().Add("nononono@nonono.com"),
										"Message content nonononononononono");
var messageid = message.Id;


var top50MessagesThatContainsHelloWordMessage = bmessage.GetAll(x=>x.Content.Contains("hello world"), 50, true);

//remove the first message from top50MessagesThatContainsHelloWordMessage
bmessage.Delete(top50MessagesThatContainsHelloWordMessage.First());


//paginate first page based in date created order by descending
var last10 = bmessage.Paginate(1,10,x=>x.DateCreated,true);

//search
var user_by_domain_email = bmessage.Search("Email", "@email.com", 1, 10, out totalrecords);
