如何向列表中添加数据值（开发篇）
上一篇中，我列举了几种管理员或者一般用户添加列表项的方式。这一篇我将从开发者的角度来完成这个操作。
作为开发人员添加列表项的方式主要有如下几种：（服务器端）对象模型，客户端对象模型以及Web Service.
1. （服务器端）对象模型。这种是开发中最常见的，可以是一个控制台程序，也可以写到你的Web Part或者Event Handler里面
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.这里需要注意的是时间类型的格式“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. 客户端对象模型。SharePoint提供了三种对象模型：client .Net OM, Silverlight OM 以及ECMAScript OM. 这里仅仅是一个Client .NET OM实例的一个演示。
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: }
