QuickStart 示例是一个 Microsoft .NET Framework 托管代码示例，它演示如何使用 ServerConnection 帮助程序类连接到 Microsoft Dynamics CRM 2011 和 Microsoft Dynamics CRM Online Web 服务和在实体上执行基本的创建、更新、检索和删除操作。

要求

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：

SDK\SampleCode\CS\QuickStart

演示

此示例使用 ServerConnection 帮助程序类和方法，向 Microsoft Dynamics 365 Web 服务验证用户。在获取对组织 Web 服务的引用后，此示例在帐户实体上执行基本的创建、更新、检索和删除操作。此示例还处理可引发的常见异常。
