encrypt SQL connectionstring c#

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
