我有一個在單元格中啟用了 TextWrapping 的 DataGrid。這意味著行沒有相同的高度。我的問題是如何遍歷行并獲取每一行的高度？DataGrid 的樣子：這是數據網格代碼：    public ObservableCollection<Article> persons = new ObservableCollection<Article>();for(int i = 0; i < 35; i++){    persons.Add(new Article("Restless legs syndrome and tis correlation with other sleep problems in the general adult population of Japan",                         "Minori Enomoto, Lan Li, Sayaka Aritake, Yukihiro Nagase, Tatsuhiko Kaji, Hirokuni Tagaya, Masato Matsuura, Yoshitaka Kaneita, Takashi Ohida, Makoto Uchiyama",                         "Sleep and Biological Rhythms",                         4));}dgMain.ItemsSource = persons;我是這樣計算的：        private void btnTest_Click(object sender, RoutedEventArgs e)    {        int k = 0;        var rows = GetDataGridRows(dgMain);        foreach (DataGridRow r in rows)        {            var rowHeight = r?.ActualHeight;            k++;        }        MessageBox.Show(k.ToString());    }這是文章類：    public class Article{    private string _title;    public string Title    {        get { return this._title; }        set { this._title = value; }    }    private string _authors;    public string Authors    {        get { return this._authors; }        set { this._authors = value; }    }    private string _journal;    public string Journal    {        get { return this._journal; }        set { this._journal = value; }    }    private int _year;    public int Year    {        get { return this._year; }        set { this._year = value; }    }    public Article(string Title, string Authors, string Journal, int Year)    {        this._title = Title;        this._authors = Authors;        this._journal = Journal;        this._year = Year;    }}
