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)
其他回答
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);
下面一行将给出应用程序路径:
var applicationPath = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName)
上述解决方案在以下情况下正常工作:
简单的应用 在另一个域,Assembly.GetEntryAssembly()将返回null DLL以字节数组的形式从嵌入式资源加载,并以Assembly.Load的形式加载到AppDomain。 使用Mono的mkbundle bundles(没有其他方法工作)
在VB.net
My.Application.Info.DirectoryPath
工作为我(应用类型:类库)。不太懂c#… 返回文件名为字符串的路径

可以使用“解决方案资源管理器”在项目中创建文件夹名称为“资源”,然后可以在“资源”中粘贴文件。
private void Form1_Load(object sender, EventArgs e) {
string appName = Environment.CurrentDirectory;
int l = appName.Length;
int h = appName.LastIndexOf("bin");
string ll = appName.Remove(h);
string g = ll + "Resources\\sample.txt";
System.Diagnostics.Process.Start(g);
}
