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。Subtracts the width and height of one Size structure from the width and height of another Size structure.

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 Size Size

Size 結構,位於減法運算子的左側。The Size structure on the left side of the subtraction operator.

sz2
Size Size Size Size

Size 結構,位於減法運算子的右側。The Size structure on the right side of the subtraction operator.

傳回

Size 結構,即減法運算的結果。A Size structure that is a result of the subtraction operation.

範例

下列程式碼範例會示範如何使用 Subtract 方法。The following code example demonstrates how to use the Subtract method. 若要執行此範例, 請將它貼到 Windows Form 中。To run this example, paste it into a Windows Form. 處理表單的Paint事件, 並從SubtractSizes Paint事件處理方法呼叫方法, 傳遞ePaintEventArgsHandle the form's Paint event and call the SubtractSizes method from the Paint event-handling method, passing e as PaintEventArgs.

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
