        { "DDATE", DateTime.Now }
    };
    var result= testdb.Upsert(dictable, dic1);

   //*****Batch insert or update Batch insert or update
    var dic3 = new Dictionary<string, object>

        { "Name", "根据_id不存在插入值" },
        { "Qty", 8000},
        { "DDATE", DateTime.Now }
    };

查询数据 Query data

   ///查找id=2的数据
    var databyid = testdb.FindByID<Dictionary<string, object>>(dictable, 2);

    //查找id=2的数据,返回模型数据。 
    //【注意】模型和数据库中的列数不一致时，需要在模型上加 [BsonIgnoreExtraElements]特性，

    var modeldata = testdb.Find<CrudTestModel1>(tb_custormer, q=>q.ID==4)?.FirstOrDefault();

    ///查找id>2的数据,返回按DDATE排序,并排除dic列的最新一条数据

    {
        double sum = datalist.Sum(s => s.FFloat);
        Assert.IsTrue(sum > 0);
    });

删除数据 delete data

    var databyid1 = testdb.FindByID<Dictionary<string, object>>(dictable,9);
    //**删除ID=8的数据
    var result = testdb.Delete(dictable, 9);
    var databyid = testdb.FindByID<Dictionary<string, object>>(dictable, 9);

           
    object strid = "10";
    var result1 = testdb.Delete("IDDATA", strid);

    var result2 = testdb.Delete("IDDATA", "9");

    //**删除qty>10的数据
    var wherresult = testdb.Delete(dictable, "_id>=10");

    //**使用sql语句删除ID = 7的数据
    string sql = $"delete from {dictable} where _id=7";
    var sqlresult = testdb.Delete(sql);

Key-Value增删改查

//单值key-value
string key = "date";
var v = DateTime.Now;
var result = testdb.SaveKeyValue(key, v);
var getv = testdb.GetKeyValue<DateTime>(key);
var Data = testdb.FindByID<CrudTestModel>(tb_custormer, 6);
if (Data != null)
{
    //单对象
    string objkey = "objectkeyvalue";
    var obj_result = testdb.SaveKeyValue(objkey, Data);

    Assert.IsTrue(testdb.KeyValueExists(objkey));
    var objv = testdb.GetKeyValue<CrudTestModel>(objkey);

    //数组列表
    string arraykey = "array_keyvalue";
    var list = new List<CrudTestModel>();
    list.Add(Data);
    objv.DDATE = DateTime.Now;
    list.Add(objv);
    var arraykey_result = testdb.SaveKeyValue(arraykey, list);

    var arraykeyv = testdb.GetKeyValue<IEnumerable<CrudTestModel>>(arraykey);

}  }

消息事件绑定（可日志输出）

    public DbTest() {
    t estdb.Message += Testdb_Message;
    }

    private void Testdb_Message((string Message, string Level, DateTime Time) obj)
    {
       Debug.WriteLine($"{obj.Time}|{obj.Level}|{obj.Message}");
    }
