最近项目需要对sharepoint 文件操作，于是自己写了一个简单的工具类分享出来：

 

namespace Microsoft.SharePoint{    using System;    using System.Collections.Generic;    using System.IO;    using System.Linq;    using System.Text;    using Microsoft.SharePoint;    using Microsoft.SharePoint.Utilities;    public class DocLibManager    {        public static void UploadFile(SPList list, string filePath, string dirName, string fileName)        {            SPFolder rootFolder = GetSPFolder(list, dirName);            SPFileCollection files = rootFolder.Files;            if (FileExists(list, dirName, fileName))            {                rootFolder.Files.Delete(SPUrlUtility.CombineUrl(rootFolder.Url ,fileName));            }            using (FileStream fs = new FileStream(filePath, FileMode.Open))            {                rootFolder.Files.Add(fileName, fs);            }        }        public static bool FileExists(SPList list, string dirName, string fileName)        {            SPFolder rootFolder = GetSPFolder(list, dirName);            string fileurl = SPUrlUtility.CombineUrl(list.ParentWebUrl, SPUrlUtility.CombineUrl(rootFolder.Url, fileName));            SPFile file = list.ParentWeb.GetFile(fileurl);            if (file != null) {                return file.Exists;            }            return false;        }        public static void RemoveFile(SPList list, string dirName, string fileName)        {            SPFolder rootFolder = GetSPFolder(list, dirName);            if (!string.IsNullOrEmpty(fileName))            {                string fileurl = SPUrlUtility.CombineUrl(list.ParentWebUrl, SPUrlUtility.CombineUrl(rootFolder.Url, fileName));                SPFile file = list.ParentWeb.GetFile(fileurl);                if (file != null && file.Exists)                    file.Delete();            }            else            {                rootFolder.Delete();            }                 }        public static SPFolder GetSPFolder(SPList list, string dirName)        {            SPFolder rootFolder = list.RootFolder;            if (string.IsNullOrEmpty(dirName) || dirName == rootFolder.Name)            {            }            else            {                SPFolder subFolder = null;                subFolder = rootFolder.SubFolders.Add(SPUrlUtility.CombineUrl(rootFolder.Url, dirName));                subFolder = rootFolder.SubFolders[dirName];                rootFolder = subFolder;            }            return rootFolder;        }    }}

 

 调用代码：

string listurl = "http://mossvr/docs/Documents/Forms/AllItems.aspx";            SPSecurity.RunWithElevatedPrivileges(delegate()            {                using (SPSite site = new SPSite(listurl))                {                    using (SPWeb web = site.OpenWeb(listurl))                    {                        SPList list = web.GetList(listurl);                        DocLibManager.UploadFile(list, @"C:\DocLib.txt", "root", "test.txt");                        DocLibManager.RemoveFile(list, "root", "test.txt");                    }                }            });
