推荐答案

您的问题不是很清楚，但据我了解，您希望从应用程序中集中一个正在运行的进程.

为此，以下是将应用程序名称作为输入的代码:

Your question is not very clear but what I understand is that, you wish to focus a running process from your application.

For that below is the code which take application name as input:

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Diagnostics;

namespace WindowsApplication1 {
  public partial class Form1 : Form {
    public Form1() {
      InitializeComponent();
    }
    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern bool SetForegroundWindow(IntPtr hWnd);

    private void button1_Click(object sender, EventArgs e) {
      Process[] procs = Process.GetProcessesByName("notepad"); //app name here
      if (procs.Length > 0) {
        // Which one?  I'll just pick the first
        if (procs[0].MainWindowHandle != IntPtr.Zero)
          SetForegroundWindow(procs[0].MainWindowHandle);
      }
    }
  }
}
