写在前面

版本兼容问题走了许多弯路，令人非常火大。软件的更新，但是配套和支持往往没有跟上，甚至反而不兼容旧版本，而网上多数博客已经不再适用，故执笔记录，希望可以帮助到你。

相关安装包已上传网盘。

Mysql

安装Mysql及相关组件，官网/网盘都可。

MySQL Installer for Windows

安装Mysql8.0，已安装可跳过此步，相关教程繁多，不再赘述。

Visual Studio

Visual Studio2022暂不支持Mysql！！！
或者Mysql暂不支持Visual Studio2022！！！
直接劝退到2019

视图->服务器资源管理器

unity

MySql.Data.dll

---

unity2020已经内置了System.Data.dll和System.Drawing.dll，只需导入MySql.Data.dll即可。
该文件在前面Connector/NET安装目录下（也已上传网盘），如：
C:\Program Files (x86)\MySQL\MySQL Connector Net 6.3.9\Assemblies\v4.0

测试脚本

---

新建两个脚本测试连接：

SqlAccess.cs

using System;using System.Data;using MySql.Data.MySqlClient;using UnityEngine;using System.Text;public class SqlAccess{public static MySqlConnection dbConnection;public SqlAccess(string host, string port, string username, string pwd, string database){//连接数据库try{string connectionString = string.Format("server = {0};port={1};database = {2};user = {3};password = {4};", host, port, database, username, pwd);Debug.Log(connectionString);dbConnection = new MySqlConnection(connectionString);dbConnection.Open();Debug.Log("连接成功！");}catch (Exception e){throw new Exception("连接失败！" + e.Message.ToString());}}//关闭连接public void Close(){if (dbConnection != null){dbConnection.Close();dbConnection.Dispose();dbConnection = null;}}//查询public DataSet SelectWhere(string tableName, string[] items, string[] col, string[] operation, string[] values){if (col.Length != operation.Length || operation.Length != values.Length)throw new Exception("col.Length != operation.Length != values.Length");StringBuilder query = new StringBuilder();query.Append("SELECT ");query.Append(items[0]);for (int i = 1; i < items.Length; ++i){query.Append(", ");query.Append(items[i]);}query.Append(" FROM ");query.Append(tableName);query.Append(" WHERE 1=1");for (int i = 0; i < col.Length; ++i){query.Append(" AND ");query.Append(col[i]);query.Append(operation[i]);query.Append("'");query.Append(values[0]);query.Append("' ");}Debug.Log(query.ToString());return ExecuteQuery(query.ToString());}//执行sql语句public static DataSet ExecuteQuery(string sqlString){if (dbConnection.State == ConnectionState.Open){DataSet ds = new DataSet();try{MySqlDataAdapter da = new MySqlDataAdapter(sqlString, dbConnection);da.Fill(ds);}catch (Exception ee){throw new Exception("SQL:" + sqlString + "/n" + ee.Message.ToString());}finally{}return ds;}return null;}}

TestSql.cs

using System.Data;using UnityEngine;public class TestSql : MonoBehaviour{    public string host = "localhost";    public string port = "3306";    public string username = "root";    public string pwd = "123456";    public string database = "demo";    void Start()    {        SqlAccess sql = new SqlAccess(host, port, username, pwd, database);        string[] items = { "name" };//字段名        string[] col = { };        string[] op = { };        string[] val = { };        DataSet ds = sql.SelectWhere("test", items, col, op, val);//替换表名test        if (ds != null)        {            DataTable table = ds.Tables[0];            foreach (DataRow row in table.Rows)            {                string str = "";                foreach (DataColumn column in table.Columns)                    str += row[column] + " ";                Debug.Log(str);            }        }    }}

测试结果

新建GameObject，将TestSql脚本绑定上去，记得修改TestSql密码数据库名字段名等。

运行测试：
