文件夹工作:

我现在知道如何设置库中文件夹的权限了:

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

    _SharePoint.Principal user = _ClientContext.Web.EnsureUser(@"oshirowanen\tom");

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

    _ClientContext.ExecuteQuery();
}

文件尝试:

我试过将文件名添加到这一行:

var _Item = _List.LoadItemByUrl("/sites/oshirodev/Library1/Folder1/File1.docx");

请注意添加到上一行末尾的 (/File1.docx)。

收到错误:

但这只是给出了一个错误:

相关信息:

这是一个在本地计算机上运行的 WinForm 应用程序，使用 C# 创建，使用 .NET 4.0。 SharePoint 版本为 2010。

问题:

如何设置特定文件的权限？我已经知道如何为特定的文件夹设置权限。

最佳答案

我查看了 2010 CSOM documentation ，并且您使用的 LoadItemByUrl 方法不存在。那是你写的扩展吗，也许this one ？如果是这样，那么问题一定出在那个扩展名中，可能在 CAML query 中。 .

作为引用，此 2010 CSOM 代码在 SharePoint 2010 实验室中运行良好。请注意，它使用 GetItemByID:

        ClientContext _ClientContext = new ClientContext("http://team/sites/Team1/");
        _ClientContext.Credentials = new NetworkCredential("administrator", "*****", "corp");
        Principal user = _ClientContext.Web.EnsureUser(@"corp\administrator");
        var _List = _ClientContext.Web.Lists.GetByTitle("Shared Documents");
        var _Item = _List.GetItemById(23);
        var roleDefinition = _ClientContext.Site.RootWeb.RoleDefinitions.GetByType(RoleType.Reader);
        var roleBindings = new RoleDefinitionBindingCollection(_ClientContext) { roleDefinition };
        _Item.BreakRoleInheritance(false, true);
        _Item.RoleAssignments.Add(user, roleBindings);
        _ClientContext.ExecuteQuery();
