2.解壓

3.添加引用（一個MySql.Data.dll足矣）

點擊“瀏覽”，到硬盤上去找

4.編寫代碼

using System;
using System.Data;
using System.Data.Common;
using MySql.Data.MySqlClient;

namespace CSMySQL {
    class Program {
        
 
static void Main(string[] args) {

            string STR_DB_CONN = "server=localhost;database=test;uid=root;password=root";
            DbConnection conn = null;
            DbCommand cmd = null;
            DbDataReader dr = null;

            conn = new MySqlConnection(STR_DB_CONN);
            conn.Open();
 
//連接到數據庫
            try
            {
                cmd = conn.CreateCommand();
                cmd.CommandText = "SELECT * FROM question";
                dr = cmd.ExecuteReader();
                while (dr.Read())
                {
                    String t = dr.GetString(0);
                    Console.WriteLine(t);
                }
            }
            
 
catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            finally
            {
                if (conn.State == ConnectionState.Open)
                {
                    conn.Close();
                }
            }
        }
    }
}
