Size.Subtract(Size, Size) 方法

定義

將另一個 Size 結構的寬度和高度減去某一個 Size 結構的寬度和高度。

public:
 static System::Drawing::Size Subtract(System::Drawing::Size sz1, System::Drawing::Size sz2);
public static System.Drawing.Size Subtract (System.Drawing.Size sz1, System.Drawing.Size sz2);
static member Subtract : System.Drawing.Size * System.Drawing.Size -> System.Drawing.Size
Public Shared Function Subtract (sz1 As Size, sz2 As Size) As Size

參數

sz1
Size

Size 結構,位於減法運算子的左側。

sz2
Size

Size 結構,位於減法運算子的右側。

傳回

Size 結構,即減法運算的結果。

範例

下列程式碼範例會示範如何使用 Subtract 方法。 若要執行此範例,請將它貼到 Windows Form 中。 處理表單的事件 Paint ,並從事件處理方法呼叫 SubtractSizes 方法 Paint ,並傳遞 ePaintEventArgs

private void SubtractSizes(PaintEventArgs e)
{
    Size size1 = new Size(100, 100);
    Size size2 = new Size(50, 50);
    e.Graphics.DrawRectangle(Pens.Black, new Rectangle(new Point(10, 10), size1));
    size1 = Size.Subtract(size1, size2);
    e.Graphics.DrawRectangle(Pens.Red, new Rectangle(new Point(10, 10), size1));
}
Private Sub SubtractSizes(ByVal e As PaintEventArgs) 
    Dim size1 As New Size(100, 100)
    Dim size2 As New Size(50, 50)
    e.Graphics.DrawRectangle(Pens.Black, _
        New Rectangle(New Point(10, 10), size1))
    size1 = System.Drawing.Size.Subtract(size1, size2)
    e.Graphics.DrawRectangle(Pens.Red, _
        New Rectangle(New Point(10, 10), size1))

End Sub
