如何在Mac上使用process.start()或等效的mono并传入参数

mono macos c#

AutomatedTester · 技术社区 · 16 年前

我正在尝试编写一些C代码来启动浏览器 Process.Start(app,args); 其中apps是浏览器的路径,例如 /Applications/Google Chrome.app/Contents/MacOS/Google Chrome args是 --no-default-browser-check

如果我这样做,它在Windows和Linux上工作

Process.Start("/Applications/Google Chrome.app/Contents/MacOS/Google Chrome","--no-first-run");

我得到

open: unrecognized option `--no-first-run'
Usage: open [-e] [-t] [-f] [-W] [-n] [-g] [-h] [-b <bundle identifier>] [-a <application>] [filenames]
Help: Open opens files from a shell.
      By default, opens each file using the default application for that file.  
      If the file is in the form of a URL, the file will be opened as a URL.
Options: 
      -a                Opens with the specified application.
      -b                Opens with the specified application bundle identifier.
      -e                Opens with TextEdit.
      -t                Opens with default text editor.
      -f                Reads input from standard input and opens with TextEdit.
      -W, --wait-apps   Blocks until the used applications are closed (even if they were already running).
      -n, --new         Open a new instance of the application even if one is already running.
      -g, --background  Does not bring the application to the foreground.
      -h, --header      Searches header file locations for headers matching the given filenames, and opens them.

我也试过了 Monobjc 尝试运行代码

// spin up the objective-c runtime
ObjectiveCRuntime.LoadFramework("Cocoa");
ObjectiveCRuntime.Initialize();
NSAutoreleasePool pool = new NSAutoreleasePool();

// Create our process
NSTask task = new NSTask();
NSPipe standardOut = new NSPipe();
task.StandardOutput = standardOut;
task.LaunchPath = @"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome";

// add some arguments
NSString argumentString = new NSString("--no-first-run");
NSArray arguments = NSArray.ArrayWithObject(argumentString);
task.Arguments = arguments;

// We should have liftoff
task.Launch();


// Parse the output and display it to the console
NSData output = standardOut.FileHandleForReading.ReadDataToEndOfFile;
NSString outString = new NSString(output,NSStringEncoding.NSUTF8StringEncoding);
Console.WriteLine(outString);

// Dipose our objects, gotta love reference counting
pool.Release();

但当我使用nunit运行代码时,它会导致nunit爆炸。

我怀疑这是个错误,但无法证明。我非常感谢你的帮助!

若要创建进程,请直接启动use exec,而不是使用操作系统的机制打开文件,必须将useShellExecute设置为false。在Linux和Windows上也是如此。

Process.Start(new ProcessStartInfo (
    "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
    "--no-first-run")
    { UseShellExecute = false });

请注意,您也可以将“open”用于您的用例,以正确运行chrome应用程序包。使用“-a”参数强制它运行特定的应用程序,使用“-n”参数打开新实例,使用“--args”传入参数:

Process.Start(new ProcessStartInfo (
    "open",
    "-a '/Applications/Google Chrome.app' -n --args --no-first-run")
    { UseShellExecute = false });

看起来像 Process 使用 open 要启动的命令行实用程序。

您应该避免直接调用可执行文件。如果应用程序已经在运行,那么它将启动它的第二个实例,而不是激活已经在运行的实例。这可能不是你想要的,而且不是所有的应用程序都能处理这个问题。

使用open,启动chrome的语法是

open -a Chrome

我不知道进程类在MacOSX上是如何工作的,但是我假设参数应该是相似的。

注意,如果您只想打开一个网页,则不应指定可执行文件;相反,只需传递URL,以便在用户的默认浏览器中打开它。这对任何平台都有效。

Process.Start("http://www.google.com");

您是否尝试过将参数连接到进程名而不是将其分隔传递?

var processName = "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome";
var args = "--no-default-browser-check";
Process.Start(String.Format("{0} {1}", processName, args));

你为什么不试试这样的东西:

Process P = new Process();                        
P.StartInfo.FileName = "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome";
P.StartInfo.Arguments = "--no-default-browser-check";
P.UseShellExecute = false;            
P.Start();
