C＃ 对sharepoint 列表基本操纵

一、更新

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（）;

二、删除

using Microsoft.SharePoint;

SPWeb site = SPControl.GetContextWeb（Context）;
SPListItemCollection items = site.Lists["ListName"].Items;
items[0].Delete（）;

三、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）;
}

四、查询数据

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
{
 ...
}
