Margins.Left 属性
定义
获取或设置左边距宽度(以百分之一英寸为单位)。Gets or sets the left margin width, in hundredths of an inch.
public:
property int Left { int get(); void set(int value); };
public int Left { get; set; }
member this.Left : int with get, set
Public Property Left As Integer

示例
在 System.Drawing 此示例中使用、 System.Drawing.Printing 和 System.IO 命名空间。Use the System.Drawing, System.Drawing.Printing, and System.IO namespaces for this example.
下面的代码示例将文档的默认页面设置设置为1英寸的左右边距,宽度为1.5 英寸。The following code example sets the default page settings for a document to left and right margins of 1 inch in width, and top and bottom margins of 1.5 inches in width.

has been set to the path of the file to print. */

PrintDocument^ pd = gcnew PrintDocument;
/* This assumes that a method, named pd_PrintPage, has been
defined. pd_PrintPage handles the PrintPage event. */
pd->PrintPage += gcnew PrintPageEventHandler( this, &Sample::pd_PrintPage );
/* This assumes that a variable of type string, named
printer, has been set to the printer's name. */

// Set the left and right margins to 1 inch.

注解
如果按毫米度量边距,请将所需的边距宽度乘以3.937,以以百分之一英寸为单位确定正确的度量值。If you measure margins in millimeters, multiply the margin width you want in millimeters by 3.937 to determine the correct measurement in hundredths of an inch. 例如,如果需要25mm 的边距,则乘以3.937,结果为98(如果向下舍入)。For example, if you want a margin of 25mm, multiply by 3.937 and the result is 98 when rounded down. 然后,将相应成员设置 Margins 为98。You would then set the appropriate Margins member to 98.
