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。
取得或設定左邊界寬度 (以百分之一英吋為單位)。
public:
property int Left { int get(); void set(int value); };public int Left { get; set; }member this.Left : int with get, setPublic Property Left As Integer屬性值
左邊界寬度 (以百分之一英吋為單位)。
例外狀況
Left 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。
