Question

我想做我在标题中写的内容。但我只是无法理解它。我也googled everythng。我想把字符串写入特殊类型FIFO的文件，由mkfifo创建（我认为）。如果有任何其他建议如何做到这一点，欢迎你。

static class PWM
{

    static string fifoName = "/dev/pi-blaster";

    static FileStream file;
    static StreamWriter write;

    static PWM()
    {
        file = new FileInfo(fifoName).OpenWrite();

        write = new StreamWriter(file, Encoding.ASCII);
    }

    //FIRST METHOD
    public static void Set(int channel, float value)
    {
        string s = channel + "=" + value;

        Console.WriteLine(s);

        write.Write(s);

        // SECOND METHOD
       // RunProgram(s);
    }

    //SECOND METHOD
    static void RunProgram(string s)
    {
        System.Diagnostics.Process proc = new System.Diagnostics.Process();
        proc.EnableRaisingEvents = true;

        proc.StartInfo.FileName = "bash";
        string x = "|echo " +s+" > /dev/pi-blaster";
        Console.WriteLine(x);

        proc.StartInfo.Arguments = x;
        proc.StartInfo.UseShellExecute = false;

        proc.StartInfo.RedirectStandardInput = true;

        proc.Start();
       // proc.WaitForExit();
    }
}

解!!!! PI-BLASTER作品：D：D（因此而失去2天） write.flush很关键，顺便说一句。

namespace PrototypeAP
{
static class PWM
{

    static string fifoName = "/dev/pi-blaster";

    static FileStream file;
    static StreamWriter write;

    static PWM()
    {
        file = new FileInfo(fifoName).OpenWrite();

        write = new StreamWriter(file, Encoding.ASCII);
    }

    //FIRST METHOD
    public static void Set(int channel, float value)
    {
        string s = channel + "=" + value + "\n";

        Console.WriteLine(s);

        write.Write(s);
        write.Flush();
    }
}
}

写入FIFO FILE，Linux＆amp;单（C＃）
