You must add a reference to assembly System.Xml

Dariusz Tomon

Hello

I upgraded my project from Visual Studio 2003 to 2005. The upgrade was
performed with no errors but now when I try to build my project (now it's in
..NET 2.0 not .NET 1.1 as was previously) I always get the following error:

Error 1 The type 'System.Xml.Serialization.IXmlSerializable' is defined in
an assembly that is not referenced. You must add a reference to assembly
'System.Xml, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089'.
C:\Inetpub\wwwroot\EuroAdresPanels\FirmaFree.cs 26 21 EuroAdresPanels

What is funny I have got a reference to System.XML.

Below is the snippet of my code (the problematic is a line with private
DataTable TKon;):

using System;

using System.Diagnostics;

//\gjo

using System.Text;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.Data.SqlClient;

using System.Drawing;

using System.Web;

using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;

using System.Xml;

namespace EuroAdresPanels

{
public class FirmaFree : System.Web.UI.WebControls.WebControl

{

private string NazwaFirmy = "";

private int id;

private DataRow[] RAdresy;

private DataTable TKon;

private DataTable TWoj;

private string emial = "";

//gjo

private DataTable TBranze;

private DataTable TSlowa;

//flaga mowiaca czy wyswietlamy tylko jedna firmy

{

TWoj = TWojewodztwo;

TKon = Kontakty;

RAdresy = rAdresy;

this.IsAlone = false;

this.TSlowa = null;

this.TBranze = null;

}

public FirmaFree(int idfirmy, DataRow[] rAdresy, DataTable Kontakty,

{

this.IsAlone = true;

this.TSlowa = TSlowa;

this.TBranze = TBranze;

this.ConnString = ConnString;
// this.IsAlone = SprawdzMaxBranz();

}

Any ideas how to deal with it?

Dariusz,
Having a "using System.Xml" directive is not the same as having a reference.
For that, you must use the Add Reference item from Solution Explorer, and
explicitly choose the assembly System.Xml from the .NET Tab list.

Hi,

using System.Xml;

does *not* mean you'd have reference to System.Xml.dll assembly. It means
you are just importing that namespace, trying to shortcut the need to type
fully-qualified names of types residing in System.Xml namespace.

Namespaces are logical concepts, and they don't necessarily always go hand
in hand with assemblies. For example: System.Configuration namespace spans
two assemblies: System.dll and System.Configuration.dll

So, try taking the reference in VS with Add reference dialog (/right-click
project in solution explorer)

Peter,

As I wrote I had the reference (in the solution explorer). I had also it in
using clause.
My problem was about having to projects in my solution and I had reference
in the wrong project. Now I added reference to the right one and it works as
expected.
Thank you very much.

If you already have the REFERENCE (not just the "using" statement)
Remove the Reference .. and re-add it.

Sometimes that'll clear it up.
