Unity 连接MYSQL

前段时间有空看了看unity添加数据，就瞎掰了下连接MYSQL,正好也在学php连接mysql的，不说了，代码如下：

using UnityEngine;
using System.Collections;
using System;
using System.Data;
using MySql.Data.MySqlClient;


public class conScript : MonoBehaviour
{
public string mystring;
public GUISkin myskin;//要想显示中文自己加个中文字体进去
void Start()
{
//改成自己的连接字符串
string connectionString =
"Server=localhost;" +
"Database=mysql;" +
"User ID=root;" +
"Password=;" +
"Pooling=false";
try
{
IDbConnection dbcon;
dbcon = new MySqlConnection(connectionString);
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();


//这里改用自己的表
string sql = "SELECT datavalue FROM home_config";
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while (reader.Read())
{
string datavalue = (string)reader["datavalue"];//datavalue改为自己表的字段


mystring += datavalue + "\n";
}
// clean up
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbcon.Close();
dbcon = null;
}
catch (Exception ex)
{
mystring = ex.ToString();//出错方便查看
}
}
void OnGUI()
{
GUI.skin = myskin;
GUI.TextArea(new Rect(10, 10, 128, 320), mystring);
}
}
