我启动了一个位于我的文件服务器上的程序。启动程序后，它在计算机管理中显示为打开文件。
有没有一种方法可以在我的程序运行时关闭此打开的文件，使它不会出现在计算机管理中？
我的代码如下。我很乐意提出改善程序的建议，但实际上我只是在寻找一种解决方案，以阻止所有这些打开文件的出现。
Program.cs-启动程序，处理启动我的应用程序的逻辑
using System;
using System.Windows.Forms;
using System.Diagnostics;
namespace IT_TaskbarApp
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
string programName = "TEG System Helper";
//Process[] proc = Process.GetProcessesByName(programName);
if (Process.GetProcessesByName(programName).Length == 1)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Primary());
}
else
{
foreach (Process p in Process.GetProcessesByName(programName))
{
if (Process.GetCurrentProcess().Id != p.Id)
{
p.CloseMainWindow();
p.Close();
p.Kill();
p.Dispose();
}
}
Main();
}
}
}
}

我不是在启动时取消程序，而是杀死了该程序的其他正在运行的实例。想法是，如果程序出现任何问题，我只需启动另一个实例并解决问题。现在并不会出错，但是将来我们将开发此程序来完成更多任务。
我唯一能看到保持打开状态的区域是当我拉 Embedded Resource tegroup.ico时，我一直在查看是否在打开它时错过了某些东西，但是我无法读完后，可以看到关闭 ManifestResourceStream 的方法。
任何提示/建议都很棒，但是我还是真的想知道是否有办法关闭这些打开文件
以下示例
如果是这种情况，我可能正在尝试解决使用 Application.Run（）的已知结果的情况，然后建议我可以使用的替代方法。我的其他想法是将程序加载到内存中并在本地启动它，不过以服务器上的.exe作为此方法的起点。
答案 0 :(得分：0)
我相信Windows不会将整个可执行文件加载到ram中。它不仅涉及PE文件资源部分中的文件。 exe的某些部分仅在引用时才加载，即使在加载了要加载的所有内容之后，Windows仍将保持打开文件句柄，直到进程关闭。试图自己关闭该手柄是一个坏主意。
c / c ++允许指定“ SWAPFILE”标志，该标志告诉Windows将整个内容放入页面文件中，但我不知道您将如何使用c＃进行此操作，甚至不知道这样做阻止窗口始终保持打开状态（我对此表示怀疑）。
如果这真的很重要，那么如果我是你的exe ...我会：
祝你好运。
