首先找到这两个东西

在Unity中的Assets文件夹新建一个名叫Plugins的子文件夹

将上面的两个插件加载进这个文件夹

 Unity中数据库操作

先引入using MySql.Data.MySqlClient;这个空间

public class mytest : MonoBehaviour {

	
	void Start () {
		Ping();
	}
	void Ping () {
		//表示服务器和所要操作的数据库，用户名和密码
		string a = "server=localhost;database=teacher;userid=root;password=root;";
		MySqlConnection con = new MySqlConnection(a);

		//打开连接
		con.Open();

		//增加
		//string sql = "insert into xinxi(name,sex,age,salary) values('邱龙华','男',21,90000)";

		//删除
		//string sql = "delete from xinxi where id=4";

		//修改
		//string sql = "update xinxi set name='彭锦涛' where id=3";
		string sql = "select * from xinxi";
		MySqlCommand com = new MySqlCommand(sql,con);
		//     if (com.ExecuteNonQuery()>0)
		//     {
		//print("OK");
		//     }
		//     else
		//     {
		//print("NO");
		//     }

		//查询
		MySqlDataReader read = com.ExecuteReader();
		//要查询的数据
		
        while (read.Read())
        {
			int id = read.GetInt32("id");
			string name = read.GetString("name");
			string sex = read.GetString("sex");
			int age = read.GetInt32("age");
			float salary = read.GetFloat("salary");
			//打印读取的数据
			print(id+"\t"+name+"\t"+sex+"\t"+age+"\t"+salary);
		}

		//关闭（释放）资源
		read.Close();
		con.Close();
	}
}
