encrypt SQL connectionstring c#

Question

I created an c# application (not asp webpage) which connects to a sql 2005 server. In my sourcecode the password and userid for this sql-server is coded plain text in ConnectionString.

SqlConnection con = new SqlConnection();
con.ConnectionString = 
         "Data Source=server1;"+
         "Initial Catalog=mydatabase;"+
         "Integrated Security=no;"+
         "User ID=admin;Password=mypassword;";
con.Open();

Is there a easy way to encrypt password or whole connectionstring, that other peoples who disassemble my tool are not able to see the password?

thanks

Answer 1

You should store your connection string in a config file and encrypt that section. See http://www.4guysfromrolla.com/articles/021506-1.aspx or http://msdn.microsoft.com/en-us/library/89211k9b%28VS.80%29.aspx.
