在C#应用程序中,我想确定另一个.NET应用程序是否是控制台应用程序。
可以使用反射API完成吗?
编辑:好的,看起来我不会得到这个问题的好答案,因为它看起来不像框架公开我想要的功能。我在PE / COFF规范中挖掘并提出了这个:
/// <summary>
/// Parses the PE header and determines whether the given assembly is a console application.
/// </summary>
/// <param name="assemblyPath">The path of the assembly to check.</param>
/// <returns>True if the given assembly is a console application; false otherwise.</returns>
/// <remarks>The magic numbers in this method are extracted from the PE/COFF file
/// format specification available from http://www.microsoft.com/whdc/system/platform/firmware/pecoff.mspx
/// </remarks>
bool AssemblyUsesConsoleSubsystem(string assemblyPath)
{
using (var s = new FileStream(assemblyPath, FileMode.Open, FileAccess.Read))
{
var rawPeSignatureOffset = new byte[4];
s.Seek(0x3c, SeekOrigin.Begin);
s.Read(rawPeSignatureOffset, 0, 4);
int peSignatureOffset = rawPeSignatureOffset[0];
peSignatureOffset |= rawPeSignatureOffset[1] << 8;
peSignatureOffset |= rawPeSignatureOffset[2] << 16;
peSignatureOffset |= rawPeSignatureOffset[3] << 24;
var coffHeader = new byte[24];
s.Seek(peSignatureOffset, SeekOrigin.Begin);
s.Read(coffHeader, 0, 24);
byte[] signature = {(byte)'P', (byte)'E', (byte)'\0', (byte)'\0'};
for (int index = 0; index < 4; index++)
{
Assert.That(coffHeader[index], Is.EqualTo(signature[index]),
"Attempted to check a non PE file for the console subsystem!");
}
var subsystemBytes = new byte[2];
s.Seek(68, SeekOrigin.Current);
s.Read(subsystemBytes, 0, 2);
int subSystem = subsystemBytes[0] | subsystemBytes[1] << 8;
return subSystem == 3; /*IMAGE_SUBSYSTEM_WINDOWS_CUI*/
}
}

这超出了托管代码的范围。从.net视图控制台和win应用程序是相同的,你必须查看PE文件头。在此页面上搜索工作“子系统”http://msdn.microsoft.com/en-us/magazine/bb985997.aspx

我认为它应该与本机应用程序相同,因此您可以将本文从C ++改编为C#以读取PE标头:How To Determine Whether an Application is Console or GUI

SHGetFileInfo功能可以执行此操作:
[DllImport("shell32.dll", CharSet=CharSet.Auto, EntryPoint="SHGetFileInfo")]
public static extern ExeType GetExeType(string pszPath, uint dwFileAttributes = 0, IntPtr psfi = default(IntPtr), uint cbFileInfo = 0, uint uFlags = 0x2000);
[Flags]
public enum ExeType
{
None = 0,
WinNT = 0x04000000,
PE = ((int)'P') | ((int)'E' << 8),
NE = ((int)'N') | ((int)'E' << 8),
MZ = ((int)'M') | ((int)'Z' << 8),
}
然后,根据规范,如果它只是MZ或PE,它在控制台中打开,否则(如果指定了版本),它在窗口中打开。
ExeType type = GetExeType("program.exe");
if(type == ExeType.PE || type == ExeType.MZ) return "console";
else return "window";

我认为没有科学的方法来确定它,我认为最接近的解决方法是使用反射来检查应用程序是否引用并加载WinForms程序集,但我不完全确定。可能试一试。
