如何从当前 .NET 程序集中检索创建日期?
我想添加一些非常简单的功能,让我的应用程序在主程序集构建日期一周后停止工作。我已经编写了在给定日期后杀死我的应用程序的代码。我只需要以编程方式从程序集中检索创建日期。

public static class ApplicationInformation

/// <summary>

private static System.DateTime RetrieveLinkerTimestamp(string filePath)
{
const int peHeaderOffset = 60;
const int linkerTimestampOffset = 8;
var b = new byte[2048];
System.IO.FileStream s = null;
try
{
s = new System.IO.FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
s.Read(b, 0, 2048);
}
finally
{
if(s != null)
s.Close();
}
var dt = new System.DateTime(1970, 1, 1, 0, 0, 0).AddSeconds(System.BitConverter.ToInt32(b, System.BitConverter.ToInt32(b, peHeaderOffset) + linkerTimestampOffset));
return dt.AddHours(System.TimeZone.CurrentTimeZone.GetUtcOffset(dt).Hours);
}
