    Cdo errors

    hi i am trying to send a mail using C# and asp.net
    but i get the following error,


    object objMail = Server.CreateOb ject("CDO.Messa ge");
    objMail.From = "chris@hotmail. com";
    objMail.To = "chris@hotmail. com";
    objMail.Subject = "Simple mail test";


    objMail.TextBod y = "Hi there; this is a test from the web
    server.";
    objMail.Fields( "urn:schemas:ht tpmail:importan ce").Value = 1;
    objMail.Fields. Update();
    objMail.();

    'object' does not contain a definition for 'From'
    'object' does not contain a definition for 'To'
    'object' does not contain a definition for 'Subject'
    and so on
    .......

    but this works fine in vb.net and asp.net

    Dim objMail As Object = Server.CreateOb ject("CDO.Messa ge")
    objMail.From = "chris@hotmail. com"
    objMail.To = "chris@hotmail. com"
    objMail.Subject = "Simple mail test"


    objMail.TextBod y = "Hi there; this is a test from the web
    server."
    objMail.Fields( "urn:schemas:ht tpmail:importan ce").Value = 1
    objMail.Fields. Update()
    objMail.()

    what do i do?
    is it possible to use the cdo.message in c#?
    cause everywhere on the net i have seen code for vb.net only and not c#

    thanx
    Chris

      Hi Chris,

      C# does not support so called late binding - that is, when method names are
      not checked at design time but the methods are called by name at run time.
      Therefore, you should add the CDO type library as a yet another project
      reference, use the new operator to create a CDO.Message instance and then
      use the created instance like you did in VB .NET:

      CDO.MessageClas s message = new CDO.MessageClas s();

      message.From = from;
      message.Sender = sender;
      message.To = to;
      message.Subject = subject;

      message.TextBod y = body;

      message.Send();

              The library is on the COM references tab. The IDE will automatically
              generate the .NET Interop assembly for you when you reference the CDO
              library from the "COM" tab.
