Question

嘿我想要打印我的Dropbox共享文件夹的成员，我混淆了如何显示它。

这是我的代码

Private Async Sub ShowMemberToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles ShowMemberToolStripMenuItem.Click
    For Each C As ListViewItem In listfile.SelectedItems


        Dim sharefolder = Await A.Files.GetMetadataAsync(direktori.Text & "/" & C.Text)
        Dim sharedfolderid = sharefolder.AsFolder.SharedFolderId.ToString
        If sharedfolderid = String.Empty Then
            MessageBox.Show("Not Shared Folder")
        Else
            Dim member = A.Sharing.ListFolderMembersAsync(sharedfolderid, limit:=100).Result.Users
            Dim list = String.Join(",", member.ToArray())
            MessageBox.Show(list)
        End If
    Next
End Sub

从Dropbox API documention我发现这个JSON代码段显示User是什么：

"membership": [
        {
            "user": {
                "display_name": "Jane P. User",
                "email": "jane@example.com",
                "email_verified": true,
                "member_id": "dbmid:abcd1234"
                "same_team": true,
                "uid": 87654321
            },
            "access_type": "owner",
            "active": true
        },
        ...
    ]

所以，当你试图做Dim list = String.Join(",", member.ToArray())时，它不知道应该输出什么，除非你覆盖该类的ToString（在这种情况下不值得这样做）。

你要做的是，在Users上运行一个选择，如下所示：

Dim usersOutput = member.Select(Function(m) m.DisplayName)
Dim list = String.Join(",", usersOutput)

显示system.collections.generic.list 1 vb.net
