Attching A Databse To The SQL Server 2000

I am using " Microsoft.SqlServer.Management.Smo". I am trying to attach a database using the AttachDatabse method in it. but it is not working for me.

 I am pasting my code as follows...tell me the problem or the right way to do it....

SqlConnection Connection = new SqlConnection("Data Source=SHEBZ; User ID=sa; Password=sa");Microsoft.SqlServer.Management.Common.ServerConnection con = new Microsoft.SqlServer.Management.Common.ServerConnection(Connection);Server ser = new Server("SHEBZ");

ser.ConnectionContext.Connect();

System.Collections.Specialized.StringCollection File = new System.Collections.Specialized.StringCollection();File.Add(@"D:Project-PartsMasterPageOfficeUploadsDb3");

try

{ser.AttachDatabase("Db3", File);

}catch (Exception ex)

{Label1.Text = "ERROR: " + ex.Message.ToString();

}
