Internal connection fatal error in opening connection - mysql

Question

In Asp.net mvc, I tried to open a sql connection, but it always gives me invalid connection fatal error.
Here is my following code:
In Web.config:
<connectionStrings>
<add name="test" connectionString="Data Source=test,3306;Initial catalog=test;User Id=xxxxx;password=xxxx;Trusted_Connection=False;Encrypt=True;" providerName="System.Data.SqlClient" />
In Controller class:
var sql = "select * from users where email = \"" + model.Email + "\" and password = \"" + model.Password +\"";
System.Diagnostics.Debug.WriteLine("return url = "+sql);
string connectionString = ConfigurationManager.ConnectionStrings["test"].ConnectionString;
using (var conn = new SqlConnection(connectionString))
{
try
{
conn.Open();
SqlCommand cmd = new SqlCommand(sql, conn);
SqlDataReader dr = cmd.ExecuteReader();
dr.Read();
System.Diagnostics.Debug.WriteLine("output = " + dr.HasRows);
conn.Close();
}
catch(Exception e)
{
System.Diagnostics.Debug.WriteLine("exception " + e.ToString());
}
}
It gives me following exception on conn.open();
System.InvalidOperationException: Internal connection fatal error. Error state: 18
Can anyone suggest what is wrong in my code.

public MySqlConnection GetMySqlConnection(string dataBase, string server,uint port,string userID,string pass)
{
MySqlConnectionStringBuilder myBuilder = new MySqlConnectionStringBuilder();
myBuilder.Database = dataBase;
myBuilder.Server = server;
myBuilder.Port = port;
myBuilder.UserID = userID;
myBuilder.Password = pass;
MySqlConnection myconn = new MySqlConnection(myBuilder.ConnectionString);
myconn.Open();
return myconn;
}
Description:
You should use MySql instead of MS SQL.
Install MySql connector net and MySql for Visual Studio ("just google them")
After install:
you must to add MySql.Data in References
in your class: using MySql.Data.MySqlClient;
