备注

此类由 PrinterSettings.PaperSources 和 PageSettings.PaperSource 属性用来获取打印机上可用的纸张来源纸盒并分别为页设置纸张来源。

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);
}
