C# 对sharepoint 列表的一些基本操作,包括添加删除查询上传文件给sharepoint list添加数据

============================================using Microsoft.SharePoint;

SPWeb site = SPControl.GetContextWeb(Context); SPListItemCollection items = site.Lists["ListName"].Items;

SPListItem item = items.Add();

item["Field_1"] = OneValue;

item["Field_2"] = TwoValue;

item.Update();

删除sharepoint list数据=============================================using Microsoft.SharePoint;

SPWeb site = SPControl.GetContextWeb(Context);

SPListItemCollection items = site.Lists["ListName"].Items;

items[0].Delete();

上传文件到sharepoint=============================================using System.IO;

using Microsoft.SharePoint;

if( htmlInputFile1.PostedFile != null ){          SPWeb site = new SPSite(destinationURL).OpenWeb();           Stream stream = htmlInputFile1.PostedFile.InputStream;

          byte[] buffer = new bytes[stream.Length];

          stream.Read(buffer, 0, (int) stream.Length);

          stream.Close();

          site.Files.Add(destinationURL, buffer);}

查询记录及更新数据===============================================using Microsoft.SharePoint;

SPWeb web = new SPSite("http://nick").OpenWeb("test");  //Open website

web.AllowUnsafeUpdates = true;

SPList list = web.Lists["ListName"];

SPQuery query = new SPQuery();

query.Query = "<Where>"+          "<And><And>"+          "<Eq><FieldRef Name=/"Filed_1/"/><Value Type=/"Text/">Test</Value></Eq>" +          "<Eq><FieldRef Name=/"Filed_2/"/><Value Type=/"Text/">" + (string)OneValue + "</Value></Eq>" +          "</And>"+          "<Eq><FieldRef Name=/"Filed_3/"/><Value Type=/"Text/">" + (string)TwoValue + "</Value></Eq>" +          "</And>"+          "</Where>";

query.RowLimit = 10;

//查询SPListItemCollection items = list.GetItems(query);try{  if (Items.Count != 0)  {     //更新sharepoint list 数据     foreach (SPListItem list in listItems)     {         list["Filed_1"] = TextBox1.text.ToString();         list["Filed_2"] = TextBox2.text.ToString();         list["Filed_3"] = TextBox3.text.ToString();

         listItem.Update();     }                         }  else  {   //将数据记录添加进sharepoint      SPListItem addlist = List.Items.Add();

      addlist["Filed_1"] = TextBox1.Text.ToString();      addlist["Filed_2"] = TextBox2.Text.ToString();      addlist["Filed_3"] = TextBox3.Text.ToString();

      addlist.Update();  }}catch{ ...}
