透過將結構的值SizeF四捨五入為最接近的整數值，將指定的Size結構轉換為結構SizeF。

public:
 static System::Drawing::Size Round(System::Drawing::SizeF value);
public static System.Drawing.Size Round(System.Drawing.SizeF value);
static member Round : System.Drawing.SizeF -> System.Drawing.Size
Public Shared Function Round (value As SizeF) As Size

參數

value
SizeF

SizeF要轉換的結構。

傳回

Size

Size這個方法轉換成的結構。

範例

以下程式碼範例示範如何使用靜態 Round 與 Truncate 方法將 a SizeF 轉換為 Size。 此範例設計用於 Windows 表單。 執行此範例時，將它貼入包含兩個 Label 名為 Label1 和 Label2的物件的表單，然後從表單的建構子呼叫此方法。

void TruncateAndRoundSizes()
{
   // Create a SizeF.
   SizeF theSize = SizeF(75.9F,75.9F);
   
   // Round the Size.
   System::Drawing::Size roundedSize = ::Size::Round( theSize );
   
   // Truncate the Size.
   System::Drawing::Size truncatedSize = ::Size::Truncate( theSize );
   
   //Print out the values on two labels.
   Label1->Text = String::Format( "Rounded size = {0}", roundedSize );
   Label2->Text = String::Format( "Truncated size = {0}", truncatedSize );
}

private void TruncateAndRoundSizes()
{

    // Create a SizeF.
    SizeF theSize = new SizeF(75.9F, 75.9F);

    // Round the Size.
    Size roundedSize = Size.Round(theSize);

    // Truncate the Size.
    Size truncatedSize = Size.Truncate(theSize);

    //Print out the values on two labels.
    Label1.Text = "Rounded size = "+roundedSize.ToString();
    Label2.Text = "Truncated size = "+truncatedSize.ToString();
}

Private Sub TruncateAndRoundSizes()

    ' Create a SizeF.
    Dim theSize As New SizeF(75.9, 75.9)

    ' Round the Size.
    Dim roundedSize As Size = Size.Round(theSize)

    ' Truncate the Size.
    Dim truncatedSize As Size = Size.Truncate(theSize)

    'Print out the values on two labels.
    Label1.Text = "Rounded size = " & roundedSize.ToString()
    Label2.Text = "Truncated size = " & truncatedSize.ToString

End Sub
