PrinterSettings.PaperSourceCollection 类

包含 PaperSource 对象的集合。

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

语法

声明
Public Class PaperSourceCollection
    Implements ICollection, IEnumerable
用法
Dim instance As PaperSourceCollection

public class PaperSourceCollection : ICollection, IEnumerable

public ref class PaperSourceCollection : ICollection, IEnumerable

public class PaperSourceCollection implements ICollection, IEnumerable

public class PaperSourceCollection implements ICollection, IEnumerable

备注

PrinterSettings.PaperSourceCollection 包含 PaperSource 实例，该实例通过 PaperSource.Kind 属性（它包含 PaperSourceKind 值之一）表示纸张来源纸盒。

通常可以通过 PageSettings.PaperSource 属性将页的纸张来源设置为有效的 PaperSource 实例（可通过 PaperSources 集合获得）。

示例

下面的代码示例用打印机支持的纸张来源填充 comboPaperSource 组合框。SourceName 被标识为向通过组合框的 DisplayMember 属性添加的项提供显示字符串的属性。该示例要求名为 printDoc 的 PrintDocument 变量和特定的组合框都已存在。

' Add list of paper sources found on the printer to the combo box.
' The DisplayMember property is used to identify the property that will provide the display string.
comboPaperSource.DisplayMember = "SourceName"

Dim pkSource As PaperSource
For i = 0 to printDoc.PrinterSettings.PaperSources.Count - 1
    pkSource = printDoc.PrinterSettings.PaperSources.Item(i)
    comboPaperSource.Items.Add(pkSource)
Next

// Add list of paper sources found on the printer to the combo box.
// The DisplayMember property is used to identify the property that will provide the display string.
comboPaperSource.DisplayMember="SourceName";

PaperSource pkSource;
for (int i = 0; i < printDoc.PrinterSettings.PaperSources.Count; i++){
    pkSource = printDoc.PrinterSettings.PaperSources[i];
    comboPaperSource.Items.Add(pkSource);
}

// Add list of paper sources found on the printer to the combo box.
// The DisplayMember property is used to identify the property that will provide the display String*.
comboPaperSource->DisplayMember = "SourceName";
PaperSource^ pkSource;
for ( int i = 0; i < printDoc->PrinterSettings->PaperSources->Count; i++ )
{
   pkSource = printDoc->PrinterSettings->PaperSources[ i ];
   comboPaperSource->Items->Add( pkSource );
}

// Add list of paper sources found on the printer to the combo box.
// The DisplayMember property is used to identify the property that
// will provide the display string.
comboPaperSource.set_DisplayMember("SourceName");

PaperSource pkSource;
for (int i = 0; i < printDoc.get_PrinterSettings().get_PaperSources().
    get_Count(); i++) {
    pkSource = printDoc.get_PrinterSettings().get_PaperSources().
        get_Item(i);
    comboPaperSource.get_Items().Add(pkSource);
}
