unity编辑器是2020.3版本，mysql是8.0，去官网下的最新的mysql for vs，一共复制的是如下四个dll。
运行以后始终报错，试了百度的许多方法也不成功，编辑器版本是.net standard2.0，不知道其中到底有什么问题
连接数据库的代码如下
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using MySql.Data;
using MySql.Data.MySqlClient;
using System;
public class SqlHelper
{
private static SqlHelper _instance = new SqlHelper();
private static string connStr = "Database=jlx2022;Data Source = 127.0.0.1; User Id = root; Password=123456;port=3306";
private string ip;
private string acc;
private string psd;
private string db;
public static SqlHelper Insatance
{
get
{
return _instance;
}
}

public IEnumerable<string> GetTables()
{
string sql = string.Format(@"select table_name from information_schema.tables where table_schema='{0}' and table_type='base table'", db);
//string sql = @"select table_name from information_schema.tables where table_schema='lwcc' and table_type='base table'";
List<string> strs = new List<string>();
var conn = GetSqlConn();
conn.Open();
MySqlCommand cmd = new MySqlCommand(sql, conn);
MySqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
strs.Add(reader[0].ToString());
}
conn.Close();
return strs;
}
/// <summary>

public void SetConnStr(string ip, string acc, string psd, string db)
{
this.ip = ip;
this.acc = acc;
this.psd = psd;
this.db = db;
connStr = string.Format("DataBase={0};Data Source= {1};User Id = {2};Password={3};port=3306;", db, ip, acc, psd);
}
public void ClearTables(IEnumerable<string> tbs)
{
string cmdText = "";
foreach (var item in tbs)
{
cmdText += string.Format("truncate table {0};", item);
}
var conn = GetSqlConn();
conn.Open();
MySqlCommand cmd = new MySqlCommand(cmdText, conn);
cmd.ExecuteNonQuery();
conn.Close();
}
}
感激不尽
