IXpsFixedDocumentReader.Uri 属性

定义

命名空间:

System.Windows.Xps.Packaging

程序集:

ReachFramework.dll

获取 FixedDocument 的统一资源标识符 (URI)。

public:
 property Uri ^ Uri { Uri ^ get(); };

public Uri Uri { get; }

member this.Uri : Uri

Public ReadOnly Property Uri As Uri

属性值

Uri

表示文档的 URI 的 A Uri 。

示例

下面的示例演示如何使用 Uri 属性。
