Adding a ListItem to a list in Sharepoint 2007

I am trying to add an item to a list in Sharepoint. At the moment I am trying to add the item via CAML

I can read the list, and query the list but I have not been able to add to the list. All the examples that I have seen update the list, I would expect that it should be reasonably similar process to add an item.

this is how I am testing it at the moment. SPLists is a web reference to开发者_如何学JAVA http:///_vti_bin/lists.asmx

    void Test(){
        var listService = new SPLists.Lists();

        string strBatch ="<Method ID='1' Cmd='New'><Field Name='Title'>Test</Field></Method>";

        XmlDocument xmlDoc = new System.Xml.XmlDocument();

        System.Xml.XmlElement elBatch = xmlDoc.CreateElement("Batch");

        elBatch.SetAttribute("OnError", "Continue");
        elBatch.SetAttribute("ListVersion", "1");

        elBatch.InnerXml = strBatch;
        XmlNode ndReturn = listService.UpdateListItems("TestList",elBatch);

        Console.Write(ndReturn.OuterXml); 
        Console.WriteLine("");

}

someone already asked a similar/same question here on SO but not answered

Edit

This is the error that I get

<Results xmlns="http://schemas.microsoft.com/sharepoint/soap/">

<Result ID="1,New">

<ErrorCode>0x81020026</ErrorCode>

<ErrorText>The list that is referenced here no longer exists.</ErrorText>

</Result>

</Results>

When I setup the web reference pointed it at the correct site and even looked at the list in sharepoint to make sure that it is there.

Looks like you probably need a small addition to your strBatch (use this article as a reference): <Field Name='ID'>New</Field>

Which means you'll have something like:

string strBatch ="<Method ID='1' Cmd='New'><Field Name='ID'>New</Field><Field Name='Title'>Test</Field></Method>";

Also, if you have any required fields on your list, you'll probably have to specify those as well.

This is what I found that solved my problem.

When I set up the Web Reference in visual studio I pointed it to the http://sharepointSite/subweb1/subweb2/_vit_bin/lists.asmx as the reference.

However when I went back and checked today it was pointing to http://sharepointSite/_vit_bin/lists.asmx. manually changing it back to http://sharepointSite/subweb1/subweb2/_vit_bin/lists.asmx in the app.config file made all the difference.

@Kit +1 I also added in you suggestion as well. With your suggetion and what I discovered about the web reference, it worked first time.

I ended up just creating a sub web with only 1 field (Title) just to get it working.
