定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得或設定上方邊界寬度 (以百分之一英吋為單位)。
public:
property int Top { int get(); void set(int value); };
public int Top { get; set; }
member this.Top : int with get, set
Public Property Top As Integer
屬性值
上方邊界寬度 (以百分之一英吋為單位)。
例外狀況
Top 屬性已設成小於 0 的值。
範例
針對此範例, System.Drawing請使用、 System.Drawing.Printing和 System.IO 命名空間。
下列程式代碼範例會將文件的默認頁面設定設為寬度為 1 英吋的左邊界和右邊界,以及寬度為 1.5 英吋的上邊界和下邊界。

備註
如果您以公厘為單位測量邊界,請將您想要以公厘為單位的邊界寬度乘以 3.937,以百分之一英吋判斷正確的度量。 例如,如果您想要 25mm 的邊界,則乘以 3.937,結果會在捨入時為 98。 然後,您會將適當的 Margins 成員設定為98。
