C#如何让命令行在WPF窗体里面运行

要在WPF窗体中运行命令行，你可以使用Process类启动命令行进程，并将其输出重定向到WPF应用程序中。以下是一个简单的示例代码，它演示了如何启动cmd.exe并在WPF窗体中显示其输出：

using System.Diagnostics;
using System.IO;

// ...

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        // Create a new ProcessStartInfo object and set the command and arguments
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.FileName = "cmd.exe";
        startInfo.Arguments = "/c dir"; // Replace "dir" with your command

        // Set the process options
        startInfo.UseShellExecute = false;
        startInfo.RedirectStandardOutput = true;
        startInfo.CreateNoWindow = true;

        // Create the process and start it
        Process process = new Process();
        process.StartInfo = startInfo;
        process.OutputDataReceived += new DataReceivedEventHandler(OutputDataReceived);
        process.Start();
        process.BeginOutputReadLine();
    }

    private void OutputDataReceived(object sender, DataReceivedEventArgs e)
    {
        // Write the output to the console
        Console.WriteLine(e.Data);

        // Update the UI on the UI thread
        this.Dispatcher.Invoke(() =>
        {
            this.OutputTextBlock.Text += e.Data + Environment.NewLine;
        });
    }
}

using System.Diagnostics;

using System.IO;

// ...

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

}

private void Button_Click(object sender, RoutedEventArgs e)

{

// Create a new ProcessStartInfo object and set the command and arguments

ProcessStartInfo startInfo = new ProcessStartInfo();

startInfo.FileName = "cmd.exe";

startInfo.Arguments = "/c dir"; // Replace "dir" with your command

// Set the process options

startInfo.UseShellExecute = false;

startInfo.RedirectStandardOutput = true;

startInfo.CreateNoWindow = true;

// Create the process and start it

Process process = new Process();

process.StartInfo = startInfo;

process.OutputDataReceived += new DataReceivedEventHandler(OutputDataReceived);

process.Start();

process.BeginOutputReadLine();

}

private void OutputDataReceived(object sender, DataReceivedEventArgs e)

{

// Write the output to the console

Console.WriteLine(e.Data);

// Update the UI on the UI thread

this.Dispatcher.Invoke(() =>

{

this.OutputTextBlock.Text += e.Data + Environment.NewLine;

});

}

在这个例子中，我们创建了一个WPF窗体，并在点击按钮时启动cmd.exe进程并将其输出重定向到窗体中。我们使用了ProcessStartInfo类来设置进程选项，并将OutputDataReceived事件附加到进程对象上。在OutputDataReceived事件处理程序中，我们使用Dispatcher对象将输出添加到TextBlock控件中，并在UI线程上更新UI。
