Margins.Top プロパティ

上部余白の幅を 1/100 インチ単位で取得または設定します。

名前空間: System.Drawing.Printing
アセンブリ: System.Drawing (system.drawing.dll 内)
構文

Visual Basic (宣言)

Public Property Top As Integer

Visual Basic (使用法)

Dim instance As Margins
Dim value As Integer

value = instance.Top

instance.Top = value

public int Top { get; set;
 }

C++

public:
property int Top {
    int get ();
    void set (int value);
}

/** @property */
public int get_Top ()

/** @property */
public void set_Top (int
 value)

JScript

public function get Top
 () : int

public function set Top
 (value : int)

プロパティ値
上部余白の幅 (1/100 インチ単位)。

例外

例外の種類	条件
ArgumentException	Top プロパティは、0 未満の値が設定されています。

解説

ミリメートル単位で余白を設定する場合は、設定するミリメートル単位の余白幅に 3.937 を掛けて 1/100 インチ単位の余白幅を割り出します。たとえば、余白を 25 mm に設定するときは、3.937 を掛けてから端数を切り捨てます。結果は 98 になります。次に、該当する Margins メンバを 98 に設定します。

使用例

この例では、System.Drawing、System.Drawing.Printing、および System.IO の各名前空間を使用します。

ドキュメントの既定のページ設定として、左右の余白の幅を 1 インチ、上下の余白の幅を 1.5 インチに設定するコード例を次に示します。
