PaperSize 类

指定纸张大小。

**命名空间:**System.Drawing.Printing
**程序集:**System.Drawing（在 system.drawing.dll 中）

语法

声明
<SerializableAttribute> _
Public Class PaperSize
用法
Dim instance As PaperSize

[SerializableAttribute] 
public class PaperSize

[SerializableAttribute] 
public ref class PaperSize

/** @attribute SerializableAttribute() */ 
public class PaperSize

SerializableAttribute 
public class PaperSize

备注

此类由 PrinterSettings.PaperSizes 和 PageSettings.PaperSize 属性分别用来获取打印机上可用的纸张大小和为页设置纸张大小。

可以使用 PaperSize 构造函数来指定自定义的页大小。只能为自定义 PaperSize 对象设置 Width 和 Height 属性值。

有关打印的更多信息，请参见 System.Drawing.Printing 命名空间概述。

示例

下面的代码示例用打印机支持的纸张大小填充 comboPaperSize 组合框。此外，创建自定义纸张大小并将它添加到组合框中。PaperName 被标识为一种属性，该属性将向通过组合框的 DisplayMember 属性添加的项提供显示字符串。该示例假定名为 printDoc 的变量 PrintDocument 和特定的组合框都已存在。

' Add list of supported paper sizes found on the printer. 
' The DisplayMember property is used to identify the property that will provide the display string.
comboPaperSize.DisplayMember = "PaperName"

Dim pkSize As PaperSize
For i = 0 to printDoc.PrinterSettings.PaperSizes.Count - 1
    pkSize = printDoc.PrinterSettings.PaperSizes.Item(i)
    comboPaperSize.Items.Add(pkSize)
Next

' Create a PaperSize and specify the custom paper size through the constructor and add to combobox.
Dim pkCustomSize1 As New PaperSize("Custom Paper Size", 100, 200)

comboPaperSize.Items.Add(pkCustomSize1)

// Add list of supported paper sizes found on the printer. 
// The DisplayMember property is used to identify the property that will provide the display string.
comboPaperSize.DisplayMember = "PaperName";

PaperSize pkSize;
for (int i = 0; i < printDoc.PrinterSettings.PaperSizes.Count; i++){
    pkSize = printDoc.PrinterSettings.PaperSizes[i];
    comboPaperSize.Items.Add(pkSize);
}

// Create a PaperSize and specify the custom paper size through the constructor and add to combobox.
PaperSize pkCustomSize1 = new PaperSize("First custom size", 100, 200);

comboPaperSize.Items.Add(pkCustomSize1);

// Add list of supported paper sizes found on the printer.
// The DisplayMember property is used to identify the property that will provide the display String*.
comboPaperSize->DisplayMember = "PaperName";
PaperSize^ pkSize;
for ( int i = 0; i < printDoc->PrinterSettings->PaperSizes->Count; i++ )
{
   pkSize = printDoc->PrinterSettings->PaperSizes[ i ];
   comboPaperSize->Items->Add( pkSize );
}

// Create a PaperSize and specify the custom paper size through the constructor and add to combobox.
PaperSize^ pkCustomSize1 = gcnew PaperSize( "First custom size",100,200 );
comboPaperSize->Items->Add( pkCustomSize1 );

// Add list of supported paper sizes found on the printer. 
// The DisplayMember property is used to identify the property that 
// will provide the display string.
comboPaperSize.set_DisplayMember("PaperName");

PaperSize pkSize;
for (int i = 0; i < printDoc.get_PrinterSettings().get_PaperSizes().
    get_Count(); i++) {
    pkSize = printDoc.get_PrinterSettings().get_PaperSizes().
        get_Item(i);
    comboPaperSize.get_Items().Add(pkSize);
}
// Create a PaperSize and specify the custom paper size through 
// the constructor and add to combobox.
PaperSize pkCustomSize1 = new PaperSize("First custom size", 100, 200);

comboPaperSize.get_Items().Add(pkCustomSize1);
