ASP.NET使用SqlConnection连接MySQL

这是web.config中保存的连接字符串:

<appSettings>
    <add key="conn" value="Driver={MySQL ODBC 5.1 Driver};server=127.0.0.1;uid=root;pwd=1234;database=gis_server;option=3"/>
    </appSettings>

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)

可能SqlConnection连接MySQL数据库吗?

答案 0 :(得分:23)

SqlConnection适用于SQL Server。您需要MySqlConnection - 这不是.NET Framework的一部分,因此您必须download it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。

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,您应该使用可以找到here的MySQL .NET连接器。

如Darren seid所说:“ SqlConnection适用于SQL Server。” 您需要从NuGet安装MySql.Data: mySql.Data

  

您还可以在程序包管理器控制台中使用 Install-Package MySql.Data

然后您可以创建MySqlConnection对象并连接到数据库:

var cnn = new MySqlConnection("my Connection String");
