Create a public class which contains the connection string and new connection creation in a single method.
use the public class method in full project any where.

public class DBConnectionClass
{
public Sqlconnection GetConnection()
{
string ConnectionString=System.Configuration.ConfigurationMangare.Connectionstring["ConnectionStringNameinWeb.config"].tostring();
Sqlconnection Cn=new SqlConnection(ConnectionString);
return Cn;
}
}
