如何在另一頁上打印

有很多數據，並且數據不能填入一頁，但是當我觸發該代碼時，我得到了一頁，其中缺少很多信息，換句話說，數據被打印到一頁上，並且當頁面填充，代碼未寫入其他頁面

Answer 1

關於使用e.HasMorePages有很多答案和文章，但是它們都會破壞您當前的布局方法。 那無濟於事。

配方：

1. 打印前整理數據。 創建一個List<DataClass> Data ，其中DataClass具有Label和Value屬性。 該列表必須是可索引的。

2. 引入lastLine項目計數器作為表單上的字段（例如docToPrint）

3. 在BeginPrint事件中將lastLine設置為0

4. 將您的Printpage事件更改為：

    var box = e.MarginBounds; //todo: calculate X, Y and H from box. while (lastLine < Data.Count) { e.Graphics.DrawStrin(Data[lastLine].Label, this.Font, Brushes.Black, X1, Y); e.Graphics.DrawStrin(Data[lastLine].Value, this.Font, Brushes.Navy, X2, Y); lastLine += 1; Y += H; if (Y >= box.Bottom) // page full break; } e.HasMorePages = lastLine < Data.Count; 

每頁有1個對Printpage事件的調用。 跟蹤下一個狀態（行）由您決定。

另外，請確保使用PrintPreviewDialog節省一些時間和紙張。
