powershell - 将新用户添加到 SharePoint 对象时，集合大小固定错误

Question

将用户添加到 SharePoint 文件夹对象时遇到以下错误：

使用“1”参数调用“添加”的异常：“集合具有固定大小。”

在 D:\User\Script1.ps1:114 char:17 $FPfolder.RoleAssignments.Add($assignment)

• CategoryInfo: NotSpecified: (:) [], MethodInvocationException
• FullyQualifiedErrorId : NotSupportedException

下面是我的代码片段：

ForEach ($FPfolderId in $FPfolderSplit)
{
    $query = New-Object Microsoft.SharePoint.SPQuery
    $query.ViewXml = "@<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='Title' /><Value Type='Text'>$FPfolderId</Value></Eq></Where></Query></View>"

    $FPfolder = $FPlist.GetItems($query)

    foreach($role in $FPfolder.RoleAssignments)  
    {
        if ($role.Member.Name.Equals($userToAction))
        {
            $FPfolder.BreakRoleInheritance($true)
            $account = $web.EnsureUser("User1")
            $assignment = New-Object Microsoft.SharePoint.SPRoleAssignment($account)
            $FPfolder.RoleAssignments.Add($assignment)
            $FPfolder.Update()
        }
    }
}

我之前已经在这里发布了关于您的问题的答案

在您的情况下$FPfolder是 ListItems 的集合。您不能将角色分配添加到集合中。

如果您确定这$FPfolder是一个仅包含一个元素（文件夹）的集合，只需[0]在$FPlist.GetItems($query).

或者您可以重命名$FPfolder并$FPfolders添加额外的 foreach 循环来迭代 SP 文件夹：

ForEach ($FPfolderId in $FPfolderSplit)
{
    $query = New-Object Microsoft.SharePoint.SPQuery
    $query.ViewXml = "@<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='Title' /><Value Type='Text'>$FPfolderId</Value></Eq></Where></Query></View>"

    $FPfolders = $FPlist.GetItems($query)
    foreach($FPfolder in $FPfolders )
    {
        foreach($role in $FPfolder.RoleAssignments) 
        {
            if ($role.Member.Name.Equals($userToAction))
            {
                $FPfolder.BreakRoleInheritance($true)
                $account = $web.EnsureUser("User1")
                $assignment = New-Object Microsoft.SharePoint.SPRoleAssignment($account)
                $FPfolder.RoleAssignments.Add($assignment)
                $FPfolder.Update()
            }
        }
    }
}
