// 注意：
// (*) 如果未指定密钥，则程序集不会被签名。
// (*) KeyName 是指已经安装在计算机上的
// 加密服务提供程序 (CSP) 中的密钥。KeyFile 是指包含
// 密钥的文件。
// (*) 如果 KeyFile 和 KeyName 值都已指定，则
// 发生下列处理：
// (1) 如果在 CSP 中可以找到 KeyName，则使用该密钥。
// (2) 如果 KeyName 不存在而 KeyFile 存在，则
// KeyFile 中的密钥安装到 CSP 中并且使用该密钥。
// (*) 要创建 KeyFile，可以使用 sn.exe（强名称）实用工具。
// 在指定 KeyFile 时，KeyFile 的位置应该相对于
// 项目输出目录，即
// %Project Directory%\obj\<configuration>。例如，如果 KeyFile 位于
// 该项目目录，应将 AssemblyKeyFile
// 属性指定为 [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
// (*) “延迟签名”是一个高级选项 - 有关它的更多信息，请参阅 Microsoft .NET 框架
