通過網絡服務訪問Sharepoint任務？

Question

我已經查看了很多關於sharepoint和通過web服務訪問對象的問題，並且我相當確信任務可以通過Lists界面訪問。

任何人都可以請我驗證一下嗎？

此外，如果任何人有任何這樣的例子，我將非常感激。我不是一個Sharepoint的人，但我需要連接到一個實例來檢索任務對象。

假設你使用Visual Studio和C＃

添加web reference到SharePoint列表Web服務 [http://[server-url]/_vti_bin/lists.asmx]

創建類似下面的一個新的類：

using System; 
using System.Text; 
using System.Xml; 
using System.Text.RegularExpressions; 
using System.Net;    

public class SharePointList 
{ 

    public void ReadSharePointList() 
    { 
    SPList.Lists listService = new SPList.Lists(); 

      try 
      { 
       // Retreive the URL to the list web service from the application cache 
       listService.Url = "http://[server-url]/_vti_bin/Lists.asmx"; 
       // Retreive the GUID for the sharepoint list 
     // To find the GUID for your list, navigate to your SharePoint list and select Settings > List Settings. 
     // The browser url will display http://[server-url]/_layouts/listedit.aspx?List=%7B7A4C9C52%2DE7E7%2D4582%2D926E%2DC70D048F9071%7D 
     // The %7B7A4C9C52%2DE7E7%2D4582%2D926E%2DC70D048F9071%7D is your GUID that you need to transform 
     // %7B = { 
     // %2D = - 
     // %7D = } 
     // e.g. %7B7A4C9C52%2DE7E7%2D4582%2D926E%2DC70D048F9071%7D = {7A4C9C52-E7E7-4582-926E-C70D048F9071} 

       string listName = {YOUR LIST GUID HERE}; 

       // SharePoint Web Serices require authentication 
       string serviceAccountID = [USERID]; 
       string serviceAccountPW = [PASSWORD]; 
       listService.Credentials = new NetworkCredential(serviceAccountID, serviceAccountPW); 

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

       XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element,"Query",""); 
       XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element,"ViewFields",""); 
       XmlNode ndQueryOptions = xmlDoc.CreateNode(XmlNodeType.Element,"QueryOptions",""); 

       ndQueryOptions.InnerXml = "<IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns>" + 
              "<DateInUtc>TRUE</DateInUtc>"; 

       ndViewFields.InnerXml = "<FieldRef Name=\"Title\" />" + 
             "<FieldRef Name=\"Search_x0020_Value\" />"; 

       // Form a query for the list items where Start Date is null or <= today's date 
       ndQuery.InnerXml = "<Where>" + 
            "<Or>" + 
            "<IsNull><FieldRef Name=\"Start_x0020_Date\"/></IsNull>" + 
            "<Leq><FieldRef Name=\"Start_x0020_Date\"/><Value Type=\"DateTime\"><Today/></Value></Leq>" + 
            "</Or>" + 
            "</Where>" + 
            "<OrderBy><FieldRef Name=\"Sort_x0020_Order\" Ascending=\"TRUE\" /></OrderBy>"; 

       XmlNode ndListItems = listService.GetListItems(listName, null, ndQuery, ndViewFields, null, ndQueryOptions, null); 

       foreach (XmlNode node in ndListItems) 
       { 
        if (node.Name == "rs:data") 
        { 
         for (int f = 0; f < node.ChildNodes.Count; f++) 
         { 
          if (node.ChildNodes[f].Name == "z:row") 
          { 
            //DO SOMETHING WITH YOUR RESULTS 
           string test = node.ChildNodes[f].Attributes["ows_Title"].Value, node.ChildNodes[f].Attributes["ows_Search_x0020_Value"].Value; 
          } 
         } 
        } 
       } 
      } 
      catch (System.Web.Services.Protocols.SoapException ex) 
      { 
      //HANDLE ERRORS 
      } 
    } 
}

是的，任務只是另一個（儘管是專業）列表。如果您在http://sharepoint/companydocs處有文檔列表，則任務存在（默認情況下）爲http://sharepoint/WorkflowTasks。
