是否可以限制哪些程序可以啓動wpf應用程序？

Question

我想爲我製作的一套wpf應用程序製作程序啓動器。啓動器將用於將用戶登錄到應用程序中，並在啓動應用程序之前執行各種測試。

我想做的是讓應用程序只能由啓動程序啓動，而不能直接運行。有沒有辦法讓我檢查應用程序的進程是否已經由啓動程序而不是用戶啓動，可能在我的AppStart（）中？

這裏有一種方法可以爲你工作。您可以註冊您的發射器組件：

然後你可以把它這樣，如果他們不從你啓動應用程序運行你的子應用程序將終止。

這是您的子應用程序使用the Windows API NtQueryInformationProcess function的一些代碼。它通過首先通過GetParentProcessID獲取其進程ID來獲得父進程，然後從該進程加載程序集並檢索其包含公鑰的完整（即「強」）名稱。

[System.Runtime.InteropServices.DllImport("ntdll.dll")] 
private static extern int NtQueryInformationProcess(IntPtr processHandle, int processInformationClass, ref NtQueryInformationProcessProcessInformation processInformation, int processInformationLength, ref int returnLength); 

/// <summary> 
/// Return the process ID of the process that is the parent of this process, if any, or else return null. 
/// </summary> 
/// <returns>Return the process ID of the process that is the parent of this process, if any, or else return null.</returns> 
/// <remarks></remarks> 
private static int? GetParentProcessID() 
{ 
    var info = new NtQueryInformationProcessProcessInformation(); 
    var returnLength = 0; 
    const int ProcessInfoClassProcessBasicInformation = 0; 
    var status = NtQueryInformationProcess(Process.GetCurrentProcess().Handle, ProcessInfoClassProcessBasicInformation, ref info, System.Runtime.InteropServices.Marshal.SizeOf(info), ref returnLength); 
    var NTStatusSuccess = 0; 
    if (status != NTStatusSuccess) throw new System.ComponentModel.Win32Exception(status); 

    try 
    { 
     return Process.GetProcessById(info.InheritedFromUniqueProcessId.ToInt32()).Id; 
    } 
    catch (ArgumentException) 
    { 
     return new int?(); //not found.    
    } 
} 

/// <summary> 
/// A structure which is required by the <see cref="NtQueryInformationProcess"/> method. 
/// </summary> 
/// <remarks></remarks> 
private struct NtQueryInformationProcessProcessInformation 
{ 
    internal IntPtr Reserved1; 
    internal IntPtr PebBaseAddress; 
    internal IntPtr Reserved2_0; 
    internal IntPtr Reserved2_1; 
    internal IntPtr UniqueProcessId; 
    internal IntPtr InheritedFromUniqueProcessId; 
} 

然後，你可以使用這樣的：

var parentProcessID = GetParentProcessID(); 
var parentProcess = parentProcessID.HasValue ? Process.GetProcessById(parentProcessID.Value) : null; 

if(parentProcess != null) 
{ 
    try 
    { 
     var strongName = Assembly.ReflectionOnlyLoadFrom(parentProcess.MainModule.FileName); 

     // check your strong name to make sure it belongs to the launcher... 
    } 
    catch (System.BadImageFormatException e) 
    { 
     // not a .net assembly, so it couldn't be your launcher app. 
    } 
} 

這僅僅是一個開始，但你的想法...
