c#嵌套CMD窗口

解决方法一:

  自己放一个文本框,改成黑色,然后输入命令,执行时,你Process.Start cmd ,此时CMD窗口不显示,然后,将CMD的返回值,再取出来,设回文本框。

  如何用这种方法实时获取cmd返回的数据,简单实现如下

 

复制代码
 1     private void OutPutForm_Shown(object sender, EventArgs e)
 2      {
 3          Control.CheckForIllegalCrossThreadCalls = false;
 4          process = new Process();
 5          p.StartInfo.FileName = "cmd.exe";
 6          p.StartInfo.UseShellExecute = false;    //是否使用操作系统shell启动
 7          p.StartInfo.RedirectStandardInput = true;//接受来自调用程序的输入信息
 8          p.StartInfo.RedirectStandardOutput = true;//由调用程序获取输出信息
 9          p.StartInfo.RedirectStandardError = true;//重定向标准错误输出
10          p.StartInfo.CreateNoWindow = true;//不显示程序窗口
11          process.OutputDataReceived += new DataReceivedEventHandler(OutputHandler);
12          process.Start();//启动程序
13          process.BeginOutputReadLine();
14      }
15      private void OutputHandler(object sendingProcess,DataReceivedEventArgs outLine)
16      {
17          if (!String.IsNullOrEmpty(outLine.Data))
18          {
19              StringBuilder sb = new StringBuilder(this.textBox1.Text);
20              this.textBox1.Text = sb.AppendLine(outLine.Data).ToString();
21              this.textBox1.SelectionStart =this.textBox1.Text.Length;
22              this.textBox1.ScrollToCaret();
23          }
24      }
复制代码

 

解决方法二:

  直接上代码

复制代码
 1    [DllImport("User32.dll ", EntryPoint = "SetParent")]
 2   private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
 3   [DllImport("user32.dll ", EntryPoint = "ShowWindow")]
 4   public static extern int ShowWindow(IntPtr hwnd, int nCmdShow);
 5   private void button3_Click(object sender, EventArgs e)
 6   {
 7     Process p = new Process();
 8       p.StartInfo.FileName = "cmd.exe ";
 9       p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized;//加上这句效果更好
10       p.Start();
11       System.Threading.Thread.Sleep(100);//加上,100如果效果没有就继续加大
12   
13       SetParent(p.MainWindowHandle, panel1.Handle); //panel1.Handle为要显示外部程序的容器
14       ShowWindow(p.MainWindowHandle, 3);
15   }
复制代码

  备注:记得引用 using System.Runtime.InteropServices;
