c# 执行命令行并返回字符串

我无法让它返回任何内容，我期待当前目录中的文件列表，但它什么也没返回。

class Program
{
    static void Main(string[] args)
    {
        PublishProject();
        Console.ReadLine();
    }

    public static void PublishProject()
    {
        //Create process
        var pProcess = new System.Diagnostics.Process
        {
            StartInfo =
                {
                    FileName = "cmd.exe",
                    Arguments = "dir",
                    UseShellExecute = false,
                    RedirectStandardOutput = true,
                    WorkingDirectory = "C:\\"
                }
        };
        pProcess.Start();
        Console.Write(pProcess.StandardOutput.ReadToEnd());
        pProcess.Close();

        Console.WriteLine("done");
    }
}

I can't get this to return anything, I'm expecting a list of files in the current directory but it's returning nothing.

class Program
{
    static void Main(string[] args)
    {
        PublishProject();
        Console.ReadLine();
    }

    public static void PublishProject()
    {
        //Create process
        var pProcess = new System.Diagnostics.Process
        {
            StartInfo =
                {
                    FileName = "cmd.exe",
                    Arguments = "dir",
                    UseShellExecute = false,
                    RedirectStandardOutput = true,
                    WorkingDirectory = "C:\\"
                }
        };
        pProcess.Start();
        Console.Write(pProcess.StandardOutput.ReadToEnd());
        pProcess.Close();

        Console.WriteLine("done");
    }
}

您可以通过将 Arguments 更改为：

Arguments = "/C dir",

/C Flag “执行字符串指定的命令，然后停止。”。如果没有这个，cmd 仍在执行，这就是为什么你不会立即得到输出。

话虽这么说，对于这个例子，我个人会使用 Directory.GetFiles或 Directory.EnumerateFiles 而不是进程。

You can make this work by changing Arguments to:

Arguments = "/C dir",

The /C Flag "Carries out the command specified by string and then stops.". Without this, cmd is still executing, which is why you get no output immediately.

That being said, for this example, I would personally use Directory.GetFiles or Directory.EnumerateFiles instead of a process.

如果您想列出目录中的文件，最好的方法是使用 System.IO 中的 Directory 类，如下所示：

using System.IO;

string[] files = Directory.GetFiles(@"C:\");

// loop to display the filenames
for (int i=0; i < files.Length(); i++) {
    Console.WriteLine(files[i]);
}

*注意，这不是完整的工作源代码，因为它不包含 main() 函数。

If you want to list down the files in the directory, the best way is to use the Directory class from System.IO as follows:

using System.IO;

string[] files = Directory.GetFiles(@"C:\");

// loop to display the filenames
for (int i=0; i < files.Length(); i++) {
    Console.WriteLine(files[i]);
}

*note that this is not a full working source code because it doesn't contain the main() function.
