如何向列表中添加資料值（開發篇）

上一篇中，我列舉了幾種管理員或者一般使用者添加清單項目的方式。這一篇我將從開發人員的角度來完成這個操作。

作為開發人員添加清單項目的方式主要有如下幾種：（伺服器端）物件模型，用戶端物件模型以及Web Service.

1. （伺服器端）物件模型。這種是開發中最常見的，可以是一個控制台程式，也可以寫到你的Web Part或者Event Handler裡面

   1:  static void AddNewItem()

   2:          {

   3:              using (SPSite site = new SPSite("http://server"))

   4:              {

   5:                  using (SPWeb web = site.OpenWeb())

   6:                  {

   7:                      SPList list = web.GetList("Lists\\Jobs");

   8:                      SPListItem item = list.AddItem();

   9:   

  10:                      item["Title"] = "SharePoint Developer";

  11:                      item["JobDescription"] = "Good at <h1>communication</h1>";

  12:   

  13:                      item["City"] = "Shenzhen";

  14:                      

  15:                      item["DueDate"]=DateTime.Now.AddMonths(1);

  16:   

  17:                      //Lookup field

  18:                      SPFieldLookupValue JobRequirement = new SPFieldLookupValue(1, "SharePoint");

  19:                      item["JobRequirement"] = JobRequirement;                   

  20:   

  21:   

  22:                      //People and Group Field

  23:                      SPFieldUserValue Manager = new SPFieldUserValue(web, web.EnsureUser("domain\\alias").ID, "User Name");

  24:                      item["Manager"] = Manager;                    

  25:   

  26:                      item.Update();    

  27:                  }

  28:              }

  29:          }

2. Web Service篇.這裡需要注意的是時間類型的格式“yyyy-MM-ddThh:mm:ssZ”。

   1:  public string AddNewItem()

   2:  {

   3:     WSLists.Lists listsWS = new Lists();

   4:     listsWS.Credentials = CredentialCache.DefaultCredentials;

   5:     listsWS.Url = "http://servername/_vti_bin/lists.asmx";

   6:   

   7:      XmlDocument doc = new XmlDocument();

   8:      XmlElement batch = doc.CreateElement("Batch");

   9:      batch.SetAttribute("OnError", "Continue");

  10:      batch.SetAttribute("ListVersion", "1");

  11:      batch.SetAttribute("ViewName", "{707B3736-82E4-4272-9E00-3A5163AD6ACD}");

  12:      string title = "SharePoint Project Manager";

  13:      string JobDescription = "PM For SharePoint";

  14:      string City = "Beijing";

  15:      string DueDate = DateTime.Now.AddDays(15).ToString("yyyy-MM-ddThh:mm:ssZ");

  16:      string JobRequirement = "1;#SharePoint";

  17:      string Manager = "1;#Name";

  18:      batch.InnerXml = string.Format("<Method ID='1' Cmd='New'>"

  19:                  + "<Field Name='ID'>New</Field>"

  20:                  + "<Field Name='Title'>{0}</Field>"

  21:                  + "<Field Name='JobDescription'>{1}</Field>"

  22:                  + "<Field Name='City'>{2}</Field>"

  23:                  + "<Field Name='DueDate'>{3}</Field>"

  24:                  + "<Field Name='JobRequirement'>{4}</Field>"

  25:                  + "<Field Name='Manager'>{5}</Field>"

  26:                  +"</Method>",

  27:                  title,JobDescription,City,DueDate,JobRequirement,Manager);

  28:      XmlNode nodeResult=listsWS.UpdateListItems("da4000b2-d13e-4420-b7bf-176ab85d91ee", batch);

  29:      return nodeResult.OuterXml;

  30:   }

3. 用戶端物件模型。SharePoint提供了三種物件模型：client .Net OM, Silverlight OM 以及ECMAScript OM. 這裡僅僅是一個Client .NET OM執行個體的一個示範。

   1:  public void AddNewItem()

   2:  {

   3:      ClientContext ctx = new ClientContext(http://servername);

   4:      var jobsList=ctx.Web.Lists.GetByTitle("jobs");

   5:   

   6:      ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();

   7:      ListItem newItem=jobsList.AddItem(itemCreateInfo);

   8:      newItem["Title"] = "Web architecture";

   9:      newItem["JobDescription"] = "<font color='red'>architecture</font>";

  10:      newItem["City"] = "Shanghai";

  11:      newItem["DueDate"] = DateTime.Now.AddDays(5);

  12:      newItem["JobRequirement"] = "3;#";

  13:      newItem["Manager"] = "1;#";

  14:      newItem.Update();

  15:      ctx.ExecuteQuery();

  16:  }
