Question

我有一个C＃命令行程序意外地以消息结束：The program '[2072] csgrep.exe' has exited with code 1 (0x1)。

缩短的代码如下：

static void Main(string[] args)
{
    try
    {
        var parser = new CommandLine.Parser(s =>
        {
            s.CaseSensitive = true;
        });

        // the application unexpectedly stops when calling this method.
        var isValid = parser.ParseArgumentsStrict(args, options);

        if (isValid)
        {
            ... run my application here
        }
        else
        {
            Console.WriteLine("Input error.");
        }
    }
    catch(Exception ex)
    {
        Console.WriteLine("Error: " + ex.Message);
    }
}

CommandLine.Parser和ParseArgumentsStrict来自nuget包“Command Line Parser Library1.9.74”（https://www.nuget.org/packages/CommandLineParser19/）

当我使用调试器“进入”时，应用程序将停在var isValid = parser.ParseArgumentsStrict(args, options);

我的问题是我真的不知道如何解决问题。我怎样才能找出问题所在？

代码可以按照以下方式更改：不使用代码1意外退出：

static void OnCommandLineParseFail()
{
    Console.WriteLine("Command line parse failure");

    Console.WriteLine("Help: " + parser.Settings.HelpWriter.ToString());
}

static void Main(string[] args)
{
    try
    {
        StringWriter t = new StringWriter();

        var parser = new CommandLine.Parser(s =>
        {
            s.CaseSensitive = true;
            s.HelpWriter = t;
            s.IgnoreUnknownArguments = false;
        });

        var isValid = parser.ParseArgumentsStrict(args, options, OnCommandLineParseFail);

        if (isValid)
        {
            ... run my application here
        }
        else
        {
            Console.WriteLine("Input error.");
        }
    }
    catch(Exception ex)
    {
        Console.WriteLine("Error: " + ex.Message);
    }
}

Nuget Command Line Parser Library 1.9.74库以代码0x01退出
