.NET Core 类库 基于NPoco访问数据库操作

一：环境

.net core 2.0 类库

在NuGet中引用：NPoco

二：类库代码

添加BaseQuery类：

using NPoco;
using System.Data.SqlClient;

namespace Query
{
    public class BaseQuery
    {
        private const string sqlConn = "server=localhost;port=5006;database=testDb;user=sa;password=123456";

        public static class Connection
        {
            public static IDatabase ConnGlobal => new Database(sqlConn, DatabaseType.SqlServer2012, SqlClientFactory.Instance);

        }
    }
}

在UserQuery类中运用

    public class UserQuery : BaseQuery
    {
        public IEnumerable<User> Find()
        {
            try
            {
                using (var db = Connection.ConnGlobal)
                {
                    var query = db.Query<User>().ToList();
                    var result = query;
                    return result;
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                return null;
            }
        }
    }

Over~
