ASP.NET使用SqlConnection连接MySQL

这是web.config保存的连接字符串：

这是连接数据库的代码：

 protected bool CheckPasswordBySqlServer(string strEmail, string strPsw) { if (strEmail.ToLower() == "admin") { return false; } string str = "select id,Rank,RankEnc,ParentUser,Company from tbl_User where userName=@UserName and password1=@password"; private string strConn = ConfigurationManager.AppSettings["conn"].ToString(); SqlConnection sqlConnection = new SqlConnection(strConn); bool flag = false; try { try { sqlConnection.Open(); SqlCommand sqlCommand = new SqlCommand(str, sqlConnection); sqlCommand.Parameters.AddWithValue("UserName", strEmail); sqlCommand.Parameters.AddWithValue("Password", strPsw); SqlDataReader sqlDataReader = sqlCommand.ExecuteReader(); if (!sqlDataReader.Read()) { flag = false; } else { this.Session["UserName"] = strEmail; this.Session["Password"] = strPsw; this.Session["LoginType"] = "Group"; this.Session["FullName"] = sqlDataReader["Company"].ToString(); if (FormsAuthentication.HashPasswordForStoringInConfigFile(string.Concat(strEmail, (char)43, sqlDataReader["Rank"].ToString()).ToLower(), "MD5") != sqlDataReader["RankEnc"].ToString().Trim()) { flag = false; } this.Session["ClientID"] = sqlDataReader["id"].ToString(); this.Session["MyLanguage"] = base.Request.Cookies["Language"].Value; this.Session["ParentUser"] = sqlDataReader["ParentUser"].ToString().Trim(); this.Session["Rank"] = sqlDataReader["Rank"].ToString(); this.Session["strConnection"] = this.strConn; flag = true; } sqlDataReader.Close(); } catch (Exception exception) { this.SetlblInfoHtml(exception.Message); } } finally { sqlConnection.Close(); } return flag; } 

但它无法连接MySQL，返回错误：

 System.ArgumentException: Keyword not supported: 'driver'. at System.Data.Common.DbConnectionOptions.ParseInternal(Hashtable parsetable, String connectionString, Boolean buildChain, Hashtable synonyms, Boolean firstKey) at System.Data.Common.DbConnectionOptions..ctor(String connectionString, Hashtable synonyms, Boolean useOdbcRules) at System.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(String connectionString, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at System.Data.SqlClient.SqlConnection.ConnectionString_Set(String value) at System.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at System.Data.SqlClient.SqlConnection..ctor(String connectionString) at Source_LoginFrm.CheckPasswordBySqlServer(String strEmail, String strPsw) at Source_LoginFrm.btnLogin_Click(String strLang) 

那可能是SqlConnection连接MySQL数据库吗？

Answer 1

SqlConnection适用于SQL Server。 您需要MySqlConnection – 这不是.NET Framework的一部分，因此您必须下载它并在项目中引用它。 然后，您可以在应用程序中创建MySqlConnection对象并连接到MySQL：

 MySqlConnection connection = new MySqlConnection(myConnString); 

您还必须使用MySqlCommand对象而不是SqlCommand对象。

Answer 2

不是我知道的，即使它会，你为什么要这样做？ 您正在使用专门为Microsoft SQL Server创建的连接对象，因此它不会以与MySQL相同的方式连接。

要访问MySQL数据库，您应该使用可在此处找到的MySQL .NET连接器。
