如何在控制台应用程序中找到应用程序的路径?
在Windows窗体中,我可以使用应用程序。StartupPath来查找当前路径,但这在控制台应用程序中似乎不可用。

技术和陷阱一直在变化。下面假设你在linux上运行。net 6控制台应用程序(在win/mac上,结果将遵循类似的模式,只需将/usr/share/和/home/username/替换为操作系统的标准位置)。
演示:
Console.WriteLine("Path.GetDirectoryName(Process.GetCurrentProcess()?.MainModule?.FileName) = " + Path.GetDirectoryName(Process.GetCurrentProcess()?.MainModule?.FileName));
Console.WriteLine("Path.GetDirectoryName(Environment.ProcessPath) = " + Path.GetDirectoryName(Environment.ProcessPath));
Console.WriteLine("Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) = " + Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));
Console.WriteLine("typeof(SomeType).Assembly.Location = " + typeof(SomeType).Assembly.Location);
Console.WriteLine("Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]) = " + Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]));
Console.WriteLine("AppDomain.CurrentDomain.BaseDirectory = " + AppDomain.CurrentDomain.BaseDirectory);
Console.WriteLine("System.AppContext.BaseDirectory = " + System.AppContext.BaseDirectory);
结果:
Path.GetDirectoryName(Process.GetCurrentProcess()?.MainModule?.FileName) = /usr/share/dotnet
Path.GetDirectoryName(Environment.ProcessPath) = /usr/share/dotnet
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) = /home/username/myproject/bin/Debug/net6.0
typeof(SomeType).Assembly.Location = /home/username/myproject/bin/Debug/net6.0
Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]) = /home/username/myproject/bin/Debug/net6.0
AppDomain.CurrentDomain.BaseDirectory = /home/username/myproject/bin/Debug/net6.0/
System.AppContext.BaseDirectory = /home/username/myproject/bin/Debug/net6.0/
每种方法都有其优点和缺点-请参阅其他答案以了解在哪种情况下使用哪种方法。
我用dotnet myapp运行我的.NET 6控制台应用程序,所以对我来说(可靠的)工作是:
typeof(SomeType).Assembly.Location
// or
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)

为什么不是p/invoke方法呢?
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
public class AppInfo
{
[DllImport("kernel32.dll", CharSet = CharSet.Auto, ExactSpelling = false)]
private static extern int GetModuleFileName(HandleRef hModule, StringBuilder buffer, int length);
private static HandleRef NullHandleRef = new HandleRef(null, IntPtr.Zero);
public static string StartupPath
{
get
{
StringBuilder stringBuilder = new StringBuilder(260);
GetModuleFileName(NullHandleRef, stringBuilder, stringBuilder.Capacity);
return Path.GetDirectoryName(stringBuilder.ToString());
}
}
}
您可以像使用应用程序一样使用它。StartupPath:
Console.WriteLine("The path to this executable is: " + AppInfo.StartupPath + "\\" + System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe");

我用dotnet myapp运行我的.NET 6控制台应用程序,所以对我来说(可靠的)工作是:
typeof(SomeType).Assembly.Location
// or
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)
你可以用这个代替。
System.Environment.CurrentDirectory
您有两个选项来查找应用程序的目录,具体选择哪个取决于您的目的。
// to get the location the assembly is executing from
//(not necessarily where the it normally resides on disk)
// in the case of the using shadow copies, for instance in NUnit tests,
// this will be in a temp directory.
string path = System.Reflection.Assembly.GetExecutingAssembly().Location;
//To get the location the assembly normally resides on disk or the install directory
string path = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
//once you have the path you get the directory with:
var directory = System.IO.Path.GetDirectoryName(path);
你可以简单地添加到你的项目引用System.Windows.Forms,然后像往常一样使用System.Windows.Forms. application . startuppath。
因此,不需要更复杂的方法或使用反射。
