Answer 1

所以，

我在select语句中添加了一个项目，一切正常。我删除它，它不是我感到困惑，但操作。

   For Each item In CheckedListBox1.CheckedItems
        Dim appQuery = _
            From c In doc.<applications>.<app> _
            Where c.<appName>.Value = item _
            Select c.<appName>, c.<appfav>, c.<appType>
        For Each result In appQuery
            result.appfav.Value = False
        Next
    Next

doc.Save(xmlFilePath)
