  • 0

This is my first attempt at doing roles for asp.net, what I have is a mySQL backend, and I want to add a bunch of roles to a user. The code i’m using below, i keep getting the error Unable to connect to SQL Server database. I’m assuming this is because the default provider refers to SQL, but i’m not able to figure out how to switch it so I can add multiple roles to a user. Thanks for the help!

using (MySqlConnection cn2 = new MySqlConnection("Server=localhost;Database=users; User=root;Password=PASSWORD;"))
            {
                cn2.Open();
                MySqlCommand cmd2 = new MySqlCommand(storedProcedureName2, cn);
                cmd2.CommandType = CommandType.StoredProcedure;
                cmd2.Parameters.Add("@usernameID", userID);
                MySqlDataReader dr2 = cmd2.ExecuteReader();
                while (dr2.Read())
                {
                    string roleName = dr2["role"].ToString();
                    Roles.AddUserToRole(userID, roleName);
                }

    You can configure the ASP.NET Membership and roles in the web.config file. Something like this would set your default provider to a MySQL backend:

    <membership defaultProvider="MySqlMembershipProvider">
<providers>
<clear />
<add name="MySqlMembershipProvider" type="MySql.Web.Security.MySqlMembershipProvider,M ySql.Web,Version=6.3.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" autogenerateschema="true" connectionStringName="LocalMySqlServer" enablePasswordRetrieval="false" enablePasswordReset="true" requireQuestionAndAnswer="false" requireUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="0" passwordStrengthRegularExpression="" applicationName="/" />
</providers>
</membership>
<profile defaultProvider="MySqlProfileProvider">
<providers>
<clear/>
<add name="MySqlProfileProvider" type="MySql.Web.Profile.MySQLProfileProvider, MySql.Web, Version=6.3.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" conectionStringName="LocalMySqlServer" applicationName="/"/>
</providers>
</profile>
<roleManager enabled="true" defaultProvider="MySqlRoleProvider">
<providers>
<clear/>
<add connectionStringName="LocalMySqlServer" applicationName="/" name="MySqlRoleProvider"
type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.3.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
</providers>
</roleManager>
<trust level="Full"/>
<machineKey validationKey="AutoGenerate" validation="SHA1"/>

    EDIT: I added the connectionStrings section below:

        <connectionStrings>
    <remove name="LocalMySqlServer"/>
    <add name="LocalMySqlServer" connectionString="Server=localhost;Database=users; User=root;Password=PASSWORD;" providerName="MySql.Data.MySqlClient"/>
    </connectionStrings>
