设置文件夹权限

Question

我有以下代码，在创建文件夹时工作正常：

public void CreateFolders()
{
    _SharePoint.ClientContext _ClientContext = new _SharePoint.ClientContext("https://sharepoint.oshiro.com/sites/oshirodev/");
    _ClientContext.Credentials = new NetworkCredential("user", "pass", "oshiro.com");

    var _web = _ClientContext._web;
    var _Root = _web.Lists.GetByTitle("Library1");
    var _folder1 = _Root.RootFolder.Folders.Add("Folder1");
    var _subfolder1 = _folder1.Folders.Add("SubFolder1");
    _folder1.Update();
    _subfolder1.Update();

    var _folder2 = _Root.RootFolder.Folders.Add("Folder2");
    var _subfolder2 = _folder2.Folders.Add("SubFolder2");
    _folder1.Update();
    _subfolder1.Update();

    _ClientContext.ExecuteQuery();
}

我了解如何更改库中所有内容的权限，例如：

public void ChangeFldPerms()
{
    _SharePoint.ClientContext _ClientContext = new _SharePoint.ClientContext("https://sharepoint.oshiro.com/sites/oshirodev/");
    _ClientContext.Credentials = new NetworkCredential("user", "pass", "oshiro.com");

    _SharePoint.Principal _user = _ClientContext.Web.EnsureUser(@"oshiro\tom");
    _SharePoint.List _item = _ClientContext.Web.Lists.GetByTitle("Library1");
    var roleDefinition = _ClientContext.Site.RootWeb.RoleDefinitions.GetByType(_SharePoint.RoleType.Reader);  //get Reader role
    var roleBindings = new _SharePoint.RoleDefinitionBindingCollection(_ClientContext) { roleDefinition };
    _item.BreakRoleInheritance(true, false);
    _item.RoleAssignments.Add(_user, roleBindings);
    _ClientContext.ExecuteQuery();
}

但我不想更改所有内容的权限，我只想为我正在创建的新文件夹设置权限。

所以我尝试了这个：

public void ChangeFldPerms2()
{
    SharePoint.ClientContext _ClientContext = new _SharePoint.ClientContext("https://sharepoint.oshiro.com/sites/oshirodev/");
    _ClientContext.Credentials = new NetworkCredential("user", "pass", "oshiro.com");

    _SharePoint.Principal _user = _ClientContext.Web.EnsureUser(@"oshiro\tom");
    _SharePoint.Folder _folder = _ClientContext.Web.GetFolderByServerRelativeUrl("/sites/oshirodev/Library1/Folder1");

    var roleDefinition = _ClientContext.Site.RootWeb.RoleDefinitions.GetByType(_SharePoint.RoleType.Reader);
    var roleBindings = new _SharePoint.RoleDefinitionBindingCollection(_ClientContext) { roleDefinition };

    _folder.ListItemAllFields.BreakRoleInheritance(true, false);
    _folder.ListItemAllFields.RoleAssignments.Add(user, roleBindings);

    _ClientContext.ExecuteQuery();
}

但是此代码在 SharePoint 2010 中不起作用，因为 ListItemAllFields 直到 Sharepoint 2013 才引入 SharePoint。

我的问题是，如何设置这些文件夹的权限以便只有特定用户可以访问它们？理想情况下，如果可以在创建文件夹时进行设置，那就太好了。如果不行，那么在创建文件夹后设置权限就可以了。

该应用程序是一个 WinForm。

Answer 1

正如您所说，ListItemAllFields 仅在 SharePoint 2013 中引入了允许您向特定用户授予权限的功能，因此您无法利用它。

如果您签出 however, you can see that there is a way around it, by installing this plugin 并创建自己的 ListExtensions class，因为它仍然不会暴露。

static class ListExtensions
{
    /// <summary>
    /// Load List Item by Url 
    /// </summary>
    /// <param name="list"></param>
    /// <param name="url"></param>
    /// <returns></returns>
    public static ListItem LoadItemByUrl(this List list, string url)
    {
        var context = list.Context;
        var query = new CamlQuery
        {
            ViewXml = String.Format("<View><RowLimit>1</RowLimit><Query><Where><Eq><FieldRef Name='FileRef'/><Value> Type='Url'>{0}</Value></Eq></Where></Query></View>", url),
        };
        var items = list.GetItems(query);
        context.Load(items);
        context.ExecuteQuery();
        return items.Count > 0 ? items[0] : null;
    }
}

其中 CamlQuery 是其中最关键的部分，并且允许您使用类似

的方式更新权限

public void ChangeFldPerms2()
{
    SharePoint.ClientContext _ClientContext = new _SharePoint.ClientContext("https://sharepoint.oshiro.com/sites/oshirodev/");
    _ClientContext.Credentials = new NetworkCredential("user", "pass", "oshiro.com");
    _SharePoint.Principal _user = _ClientContext.Web.EnsureUser(@"oshiro\tom");

    var list = _ClientContext.Web.Lists.GetByTitle("Library1");
    var folderItem = list.LoadItemByUrl("/sites/oshirodev/Library1/Folder1");
    var roleDefinition = _ClientContext.Site.RootWeb.RoleDefinitions.GetByType(_SharePoint.RoleType.Reader);
    var roleBindings = new _SharePoint.RoleDefinitionBindingCollection(_ClientContext) { roleDefinition };
    folderItem.BreakRoleInheritance(true, false);
    folderItem.RoleAssignments.Add(user, roleBindings);

    _ClientContext.ExecuteQuery();
}

另一种方式。如果你可以访问应用服务器，你可以给创建iis应用程序池的权限。
