ClickOnce应用程序将不接受命令行参数

问题描述

我有一个采用命令行参数的VB.NET应用程序。

I have a VB.NET application that takes command-line arguments.

只要我关闭Visual Studio的ClickOnce安全设置，它在调试时就可以正常工作。

It works fine when debugging provided I turn off Visual Studio's ClickOnce security setting.

当我关闭尝试通过ClickOnce将应用程序安装在计算机上，并尝试使用参数运行它。

The problem occurs when I try to install the application on a computer via ClickOnce and try to run it with arguments. I get a crash when that happens (oh noes!).

此问题有一种解决方法：将文件从最新版本的publish文件夹移动到计算机的C：驱动器，然后从.exe中删除 .deploy。从C：驱动器运行应用程序，它将可以很好地处理参数。

There is a workaround for this issue: move the files from the latest version's publish folder to a computer's C: drive and remove the ".deploy" from the .exe. Run the application from the C: drive and it will handle arguments just fine.

有没有比我上面的解决方法更好的方法了？

Is there a better way to get this to work than the workaround I have above?

谢谢！

推荐答案

命令行参数仅适用于通过网址运行ClickOnce应用程序。

"Command-line arguments" only work with a ClickOnce app when it is run from a URL.

例如，这是您应启动应用程序以附加一些运行时参数的方式：

For example, this is how you should launch your application in order to attach some run-time arguments:

我有以下C＃我用来解析ClickOnce激活URL和命令行参数的代码类似：

I have the following C# code that I use to parse ClickOnce activation URL's and command-line arguments alike:

public static string[] GetArguments()
{
    var commandLineArgs = new List<string>();
    string startupUrl = String.Empty;

    if (ApplicationDeployment.IsNetworkDeployed &&
        ApplicationDeployment.CurrentDeployment.ActivationUri != null)
    {
        // Add the EXE name at the front
        commandLineArgs.Add(Environment.GetCommandLineArgs()[0]);

        // Get the query portion of the URI, also decode out any escaped sequences
        startupUrl = ApplicationDeployment.CurrentDeployment.ActivationUri.ToString();
        var query = ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
        if (!string.IsNullOrEmpty(query) && query.StartsWith("?"))
        {
            // Split by the ampersands, a append a "-" for use with splitting functions
            string[] arguments = query.Substring(1).Split(new[] { '&' }, StringSplitOptions.RemoveEmptyEntries).Select(a => String.Format("-{0}", HttpUtility.UrlDecode(a))).ToArray();

            // Now add the parsed argument components
            commandLineArgs.AddRange(arguments);
        }
    }
    else
    {
        commandLineArgs = Environment.GetCommandLineArgs().ToList();
    }

    // Also tack on any activation args at the back
    var activationArgs = AppDomain.CurrentDomain.SetupInformation.ActivationArguments;
    if (activationArgs != null && activationArgs.ActivationData.EmptyIfNull().Any())
    {
        commandLineArgs.AddRange(activationArgs.ActivationData.Where(d => d != startupUrl).Select((s, i) => String.Format("-in{1}:\"{0}\"", s, i == 0 ? String.Empty : i.ToString())));
    }

    return commandLineArgs.ToArray();
}

主要功能如下：

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        var commandLine = GetArguments();
        var args = commandLine.ParseArgs();

        // Run app
    }
