在打印时控制行间距！！

在打印时控制行间距和对齐方式怎么写啊。谢谢了。
我知道用PrintPageEventArgs.Graphics 最后一个参数来控制。但是那个参数应该怎么写我不会！！

获取用于绘制页的 Graphics。

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

语法

Visual Basic（声明）
Public ReadOnly Property Graphics As Graphics

Visual Basic（用法）
Dim instance As PrintPageEventArgs Dim value As Graphics value = instance.Graphics

C#
public Graphics Graphics { get; }

C++
public: property Graphics^ Graphics { Graphics^ get (); }

J#
/** @property */ public Graphics get_Graphics ()

JScript
public function get Graphics () : Graphics

属性值

用于绘制页的 Graphics。

示例

下面的代码示例假定已经在 Form 上创建了一个 Button。示例中的 printButton_Click 方法创建 PrintDocument 类的一个实例，调用 pd_PrintPage 方法，然后打印 pd_PrintPage 方法中指定的 .bmp 文件。若要运行该示例，请更改要打印的位图的路径。

将 System.ComponentModel、System.Collections、System.Drawing、System.Drawing.Printing、System.Resources 和 System.Windows.Forms 命名空间用于此示例。

Visual Basic	复制代码

Dim pd As New PrintDocument() AddHandler pd.PrintPage, AddressOf Me.pd_PrintPage pd.Print() Catch ex As Exception MessageBox.Show("An error occurred while printing", _ ex.ToString()) End Try End Sub ' Specifies what happens when the PrintPage event is raised.
