.net core 连接 mssql数据库

跟在  .net 里面一样的连接方法，只是不能自动添加引用 dll

1、管理 nuget  ，添加以下两个引用(重要)

PM>  Install-Package System.Data.Common

PM>  Install-Package System.Data.SqlClient

2、测试代码

static void Main(string[] args)
        {
            using (SqlConnection con = new SqlConnection("Data Source=XFSERVER\\SQL2016;Initial Catalog=T2;Persist Security Info=True;User ID=sa;Password=xinfu978"))
            {
                con.Open();
                try
                {
                    using (SqlCommand command = new SqlCommand("SELECT TOP(10) * FROM T2", con))
                    {
                        SqlDataReader read=  command.ExecuteReader();
                        while (read.Read())
                        {
                            Console.WriteLine(read["fName"]  + " == " + read["fAddTime"]);
                        }
                    }
                }
                catch
                {
                    Console.WriteLine("Something went wrong");
                }
            }
            Console.ReadKey();
        }
