示例：将属性列表元数据转储到文件
发布日期： 2017年1月
适用于： Dynamics 365 (online),Dynamics 365 (on-premises),Dynamics CRM 2016,Dynamics CRM Online
此示例代码适用于 Microsoft Dynamics 365（在线或本地）。下载 Microsoft Dynamics CRM SDK 包。 它可能位于下载包的以下位置：
SampleCode\CS\Metadata\Attributes\DumpPicklistInfo.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元数据输出到 XML 文件。 它使用 RetrieveAllEntitiesRequest 消息。
以下示例在 \Entities\bin\Debug\AttributePicklistValues.xml 创建新文件。 您可以在 Microsoft Office Excel 中打开该文件以查看表格报表。 这对于查找每个选择列表的有效值非常有用。 也可以在每个实体的“EntityName Entity OptionSet 特性元数据”主题中找到此信息。
