Question

我开发了一个控制台应用程序，它将带有密码的目录中的文件压缩到目标文件夹。我正在使用密码将目录中的文件压缩到目标文件夹。

这是代码。在我的本地电脑上工作正常。我已经为这个应用程序创建了设置并安装在我的PC以及其他PC上。在我的电脑上工作正常。但在其他PC上，它给予例外。你能告诉我可能是什么问题，我该如何解决？是与此权限相关的问题还是其他一些问题。

我认为这段代码很奇怪：

System.DateTime Timestamp = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);
string strFileName = Timestamp.ToShortDateString();
strFullFilePath = args[i] + strFileName + ".zip";

首先，你可以写

DateTime Timestamp = DateTime.Now;

然后ToShortDateString取决于CurrentCulture。强迫你想要的东西（例如：）

String strFileName = Timestamp.ToString("yyyyMMdd");

在我看来，这是例外。如果文化错误，您可以在格式字符串中添加“/”。

然后，使用Path.Combine而不是操作符+（没有丢失斜杠的错误）

strFullFilePath = Path.Combine(args[i], strFileName + ".zip");

修改对于那些无法格式化DateTime的人来说，这里是我的代码（并且有效）：

public static class Constantes { public const String DateTimePattern = "yyyyMMddHHmmss"; } public class SaveProcessViewModel : NotificationObject { [...] String zipFileName = System.Environment.MachineName + "-" + DateTime.Now.ToString(Constantes.DateTimePattern) + ".zip"; String tempZipFile = Path.Combine(Path.GetTempPath(), zipFileName); zip.Save(tempZipFile); [...] }
