SharePoint 服务器端对象模型操作文档库(上传/授权/查看权限)

　　简介：上传文档到文档库，并对项目级授权，查看项目级权限方法
//在列表根目录下创建文件夹
public static string CreatFolderToSPDocLib(string strFolderName, string strDocLibName)
{
string FolderPath = string.Empty;

try
{
using (SPSite site = new SPSite(SiteUrl))
{
using (SPWeb web = site.OpenWeb())
{
web.AllowUnsafeUpdates = true;
SPListCollection lists = web.GetListsOfType(SPBaseType.DocumentLibrary);
lists.IncludeRootFolder = true;
SPList list = lists[strDocLibName];
list.EnableFolderCreation = true;
SPListItem item = list.Items.Add(list.RootFolder.ServerRelativeUrl, SPFileSystemObjectType.Folder, strFolderName);
item.Update();
list.Update();
FolderPath = item["FileRef"].ToString();
web.AllowUnsafeUpdates = false;
}
}
}
catch
{
}
return FolderPath;
}

　　//上传文件到文件夹，并授权给相关用户
public static bool UpLoadFileToFolder(byte[] FileStream, string FileName, string FolderPath, string allLoginName)
{
try
{
using (SPSite site = new SPSite(SiteUrl))
{
using (SPWeb web = site.OpenWeb())
{
web.AllowUnsafeUpdates = true;
SPFolder folder = web.GetFolder(FolderPath);

SPListItem listItem = folder.Files.Add(FileName, FileStream).Item;

//断开原来列表项所继承的权限,使其可以设置独立权限
listItem.BreakRoleInheritance(true);
//将原来所继承的权限通通移除
foreach (SPRoleAssignment roleAssignment in listItem.RoleAssignments)
{
roleAssignment.RoleDefinitionBindings.RemoveAll();
roleAssignment.Update();
listItem.Update();
}
//获取将要设置权限的用户
SPUser myUser = web.EnsureUser(allLoginName);
//定义权限分配
SPRoleAssignment myRoleAssignment = new SPRoleAssignment(myUser.LoginName, myUser.Email, myUser.Name, myUser.Notes);
//绑定设置的权限
myRoleAssignment.RoleDefinitionBindings.Add(web.RoleDefinitions.GetByType(SPRoleType.Reader));
//把这个权限加到我们的列表中
listItem.RoleAssignments.Add(myRoleAssignment);
listItem.Update();

web.AllowUnsafeUpdates = false;
return true;
}
}
}
catch
{
return false;
}
}

//通过ID获取列表项
public static string GetRoleAssignmentsOfSPListItem(string ListName, int ItemID)
{
string reValue = string.Empty;
try
{
using (SPSite site = new SPSite(SiteUrl))
{
using (SPWeb web = site.OpenWeb())
{

SPList list = web.Lists[ListName];
SPListItem item = list.Items.GetItemById(ItemID);
SPRoleAssignmentCollection Rolecoll = item.RoleAssignments;
foreach (SPRoleAssignment role in Rolecoll)
{
for (int i = 0; i < role.RoleDefinitionBindings.Count; i++)
{
reValue += (role.Member.LoginName + ":" + role.RoleDefinitionBindings[i].Name + ":" + role.RoleDefinitionBindings[i].BasePermissions.ToString());
}
}

}
}

return reValue;
}
