我构建了一个基本的
Windows窗体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.
具体来说,当有人点击.exe运行它时,如果它在特定日期之后,则删除.exe.这可能吗？如果是,我该怎么做？
我认为我的代码看起来像这样：
DateTime expiration = new DateTime(2013,10,31) //Oct. 31,2013
If (DateTime.Today > expiration)
{
//command to self-delete
}
else
{
//proceed normally
}
解决方法
您必须确保在要删除文件时已关闭应用程序.我会建议类似下面的东西 – 当然你需要做一些修改.
以下示例适用于Windows,需要针对其他操作系统进行修改.
/// <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");
}
