public float Left { get; set; }

型別：System.Single
Button 左緣與文件左緣之間的距離 (以點為單位)。

備註

範例

下列程式碼範例會示範 Button 控制項的 Left 屬性。 此範例會將兩個名為 sizeButton 和 locationButton 的 Button 控制項加入文件中。 當按下 sizeButton 時，會調整 Height 和 Width 屬性，好讓按鈕得以變更大小。 當按下 locationButton 時，會調整 Top 和 Left 屬性，好讓按鈕得以變更位置。 在修改每個按鈕後，此範例便會在訊息方塊中顯示已按下按鈕的新 Right、Bottom、Height、Width、Top 和 Left 屬性值。

這是示範文件層級自訂的範例。
