c#如何获取文件相关信息(文件名与版本信息等)

FileInfo fi = new FileInfo(@"C:file.txt");
if(fi.Exists)
{
  Console.WriteLine("Filename : {0}",fi.Name);
  Console.WriteLine("Path : {0}",fi.FullName);
}

//
// 有关程序集的常规信息是通过下列
// 属性集控制的。更改这些属性值可修改与程序集
// 关联的信息。
//
[assembly: AssemblyTitle("")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]
//
// 程序集的版本信息由下列 4 个值组成:
//
// 主版本
// 次版本
// 内部版本号
// 修订号
//
// 您可以指定所有这些值，也可以使用“修订号”和“内部版本号”的默认值，方法是按
// 如下所示使用 '*':
 
[assembly: AssemblyVersion("1.0.*")]
 
//
// 要对程序集进行签名，必须指定要使用的密钥。有关程序集签名的更多信息，请参考
// Microsoft .NET Framework 文档。
//
// 使用下面的属性控制用于签名的密钥。
//
// 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 Framework
// 文档。
