话不多说直接上代码
连接字符串:
{ "AppSettings": { "mongodb": "mongodb://用户名:密码@IP地址:端口号" } }
主体代码:
using ABCDEFG.Config;
using MongoDB.Driver;
using System;
using System.Collections.Generic;
using System.Linq.Expressions;
using System.Text;
namespace Mongodb
{
public class MongoContext
{
public MongoContext()
{
Client = new MongoClient(ABCDEFG.GetAppSetting("mongodb"));
}
public MongoContext(string connectionName)
{
Client = new MongoClient(MengTConfig.GetAppSetting(connectionName));
}
private MongoClient Client { get; set; }
private IMongoDatabase DataBase { get => Client.GetDatabase("MengTLog"); }
public IMongoCollection<T> DbSet<T>() where T : IMongoModel => DataBase.GetCollection<T>("MengTLog.Logger");
}
public static class MongoExtend
{
public static void Add<T>(this IMongoCollection<T> collenction, T Model) where T : IMongoModel
=> collenction.InsertOne(Model);
public static void AddList<T>(this IMongoCollection<T> collenction, List<T> Model) where T : IMongoModel
=> collenction.InsertMany(Model);
/// <summary>
/// 查找第一个
/// </summary>
public static T FirstOrDefault<T>(this IMongoCollection<T> collenction,Expression<Func<T, bool>> expression) where T : IMongoModel
{
if (expression == null) { throw new ArgumentNullException("参数无效"); }
return collenction.Find(expression).FirstOrDefault();
}
/// <summary>
/// 查找符合数据列表
/// </summary>
public static List<T> FindToList<T>(this IMongoCollection<T> collenction, Expression<Func<T, bool>> expression) where T : IMongoModel
{
if (expression == null) { throw new ArgumentNullException("参数无效"); }
return collenction.Find(expression).ToList();
}
/// <summary>
/// 删除全部匹配数据
/// </summary>
public static void Delete<T>(this IMongoCollection<T> collenction, Expression<Func<T, bool>> expression) where T : IMongoModel
{
if (expression == null) { throw new ArgumentNullException("参数无效"); }
collenction.DeleteManyAsync(expression);
}
/// <summary>
/// 删除一个
/// </summary>
public static void DeleteOne<T>(this IMongoCollection<T> collenction, Expression<Func<T, bool>> expression) where T : IMongoModel
{
if (expression == null) { throw new ArgumentNullException("参数无效"); }
collenction.DeleteOneAsync(expression);
}
}
}
IMongoModel:
using MongoDB.Bson;
using System;
using System.Collections.Generic;
using System.Text;
namespace Mongodb
{
public partial class IMongoModel
{
/// <summary>
/// 基础ID
/// </summary>
public ObjectId _id { get; set; }
}
}
值得注意的是:需引用MongoDB.BSon与MongoDB.Driver
VS2017若在引用包后,还是无法找到命名空间,重启VS即可。
ABCDEFG.GetAppSetting("mongodb"));读取配置文件
