示例：将实体关系信息转储到文件

 

发布日期： 2016年11月

适用于： Dynamics CRM 2015

此示例代码适用于 Microsoft Dynamics CRM 2015 和 Microsoft Dynamics CRM Online 2015 更新。下载 Microsoft Dynamics CRM SDK 包。 它可能位于下载包的以下位置：

SampleCode\CS\Metadata\Relationships\DumpRelationships.cs

要求

有关运行此 SDK 中提供的示例代码的要求的详细信息，请参阅使用示例和帮助程序代码。

演示

此示例演示如何将所有实体关系元数据写出到 XML 文件。 它使用 RetrieveAllEntitiesRequest 消息。

以下示例在 \Relationships\bin\Debug\RelationshipInfo.xml 中创建一个新文件。 您可以在 Microsoft Office Excel 中打开该文件以查看表格报表。 您可能需要这些信息来发现报表中使用的某个自定义实体的实体类型代码。
