Dim listService As New Web_Reference_Folder.Lists()
listService.Credentials = System.Net.CredentialCache.DefaultCredentials

Dim ndAttach As XmlNode = 
    listService.GetAttachmentCollection("List_Name", "1")
Dim ndsAttach As XmlNodeList = ndAttach.ChildNodes
Dim i As Integer

For i = 0 To ndsAttach.Count - 1

    Dim delUrl As String = ndsAttach(i).InnerText

    listService.DeleteAttachment("List_Name", "1", delUrl)

Next i
Web_Reference_Folder.Lists listService = new Web_Reference_Folder.Lists();
listService.Credentials= System.Net.CredentialCache.DefaultCredentials;

XmlNode ndAttach = 
    listService.GetAttachmentCollection("List_Name", "1");
XmlNodeList ndsAttach = ndAttach.ChildNodes;

for (int i=0; i<ndsAttach.Count; i++)
    string delUrl = ndsAttach[i].InnerText;
    listService.DeleteAttachment("List_Name", "1", delUrl);
