database connect problem

Got error message in conn.Open(). Please see attached code file and error message file.

try
{
conn = new SqlConnection(connString);
conn.Open();
}
catch (System.Exception e)
{
Debug.LogError("errors ======> " + e);
}

This code is working properly in VS and monoDeveloper but got error in Unity

Please advise.
