SPListItem item = items.Add();

item["Field_1"] = OneValue;

item["Field_2"] = TwoValue;

item.Update();

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

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();
