SqlConnection con = new SqlConnection("Data Source = emisdemo.db.8972447.hostedresource.com ; Initial Catalog = dbname;用户ID = isha;密码=''ish @ 123'');

con.Open();

这段代码在一个应用程序中有效，但在其他应用程序中无效

SqlConnection con = new SqlConnection("Data Source=emisdemo.db.8972447.hostedresource.com; Initial Catalog=dbname; User ID=isha; Password=''ish@123''");

con.Open();

this piece of code is working in one application but not in other application
