PrinterSettings.PrinterResolutionCollection 类

包含 PrinterResolution 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 PrinterResolutionCollection
    Implements ICollection, IEnumerable
用法
Dim instance As PrinterResolutionCollection

public class PrinterResolutionCollection : ICollection, IEnumerable

public ref class PrinterResolutionCollection : ICollection, IEnumerable

public class PrinterResolutionCollection implements ICollection, IEnumerable

public class PrinterResolutionCollection implements ICollection, IEnumerable

备注

PrinterSettings.PrinterResolutionCollection 包含 PrinterResolution 实例，该实例通过 PrinterResolution.Kind 属性（它包含 PrinterResolutionKind 值之一）表示受支持的打印机分辨率。

通常可以通过 PageSettings.PrinterResolution 属性将打印机分辨率设置为有效的 PrinterResolution 实例（可通过 PrinterResolutions 集合获得）。

如果 PrinterResolutionKind 为 Custom，则使用 X 和 Y 属性分别确定水平方向和垂直方向的自定义打印机分辨率。

示例

下面的代码示例用受支持的分辨率填充 comboPrintResolution 组合框。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 printer resolutions found on the printer to the combobox.
' The PrinterResolution's ToString() method will be used to provide the display string.
Dim pkResolution As PrinterResolution
For i = 0 to printDoc.PrinterSettings.PrinterResolutions.Count - 1
    pkResolution = printDoc.PrinterSettings.PrinterResolutions.Item(i)
    comboPrintResolution.Items.Add(pkResolution)
Next

// Add list of printer resolutions found on the printer to the combobox.
// The PrinterResolution's ToString() method will be used to provide the display string.

PrinterResolution pkResolution;
for (int i = 0; i < printDoc.PrinterSettings.PrinterResolutions.Count; i++){
    pkResolution = printDoc.PrinterSettings.PrinterResolutions[i];
    comboPrintResolution.Items.Add(pkResolution);
}

// Add list of printer resolutions found on the printer to the combobox.
// The PrinterResolution's ToString() method will be used to provide the display String.
PrinterResolution^ pkResolution;
for ( int i = 0; i < printDoc->PrinterSettings->PrinterResolutions->Count; i++ )
{
   pkResolution = printDoc->PrinterSettings->PrinterResolutions[ i ];
   comboPrintResolution->Items->Add( pkResolution );
}

// Add list of printer resolutions found on the printer to the combobox.
// The PrinterResolution's ToString() method will be used to 
// provide the display string.
PrinterResolution pkResolution;
for (int i = 0; i < printDoc.get_PrinterSettings().
    get_PrinterResolutions().get_Count(); i++) {
    pkResolution = printDoc.get_PrinterSettings().
        get_PrinterResolutions().get_Item(i);
    comboPrintResolution.get_Items().Add(pkResolution);
}
