C#内置的.exe是否可以自删除? [英] Is it possible for a C# built .exe to self-delete?

问题描述

我构建了一个基本的Windows Form应用程序.我想这样做，以便我的程序在我选择的日期之后删除自己.

I built a basic Windows Form app. I want to make it so that my program deletes itself after a date of my choosing.

具体来说，当有人单击.exe来运行它时，如果在某个日期之后，该.exe将被删除.这可能吗?如果是，该怎么办?

Specifically, when someone clicks on the .exe to run it, and if it's after a certain date, the .exe is deleted. Is this possible? If yes, how do I do this?

我认为我的代码应如下所示:

I think my code would look something like this:

DateTime expiration = new DateTime(2013, 10, 31) //Oct. 31, 2013

If (DateTime.Today > expiration) 
{
    //command to self-delete
}
else  
{
    //proceed normally
}

推荐答案

您必须确保，要删除文件时，您的应用程序已关闭.我建议与以下内容类似-当然，您需要进行一些修改.

You must make sure, that your application is already closed when you want to delete the file. I would suggest something similar to the following one - you will need some modifications of course.

以下示例在Windows上运行，并且需要针对其他操作系统进行修改.

The following example works on windows and needs to be modified for other operating systems.

/// <summary>
/// Represents the entry point of our application.
/// </summary>
/// <param name="args">Possibly spcified command line arguments.</param>
public static void Main(string[] args)
{
    string batchCommands = string.Empty;
    string exeFileName = Assembly.GetExecutingAssembly().CodeBase.Replace("file:///",string.Empty).Replace("/","\\");

    batchCommands += "@ECHO OFF\n";                         // Do not show any output
    batchCommands += "ping 127.0.0.1 > nul\n";              // Wait approximately 4 seconds (so that the process is already terminated)
    batchCommands += "echo j | del /F ";                    // Delete the executeable
    batchCommands += exeFileName + "\n";
    batchCommands += "echo j | del deleteMyProgram.bat";    // Delete this bat file

    File.WriteAllText("deleteMyProgram.bat", batchCommands);

    Process.Start("deleteMyProgram.bat");
}
