如何将c#中的cmd命令输出到标签

我为c#表单应用程序中的runcmd命令编写了代码。现在我想在winform中将cmd输出到标签。我编写了一个代码。但它给了我以下的错误

---

System.dll中发生类型为“System.InvalidOperationException”的未处理异常 其他信息：StandardOut尚未重定向或流程尚未启动。

private void button1_Click(object sender, EventArgs e)
{
    System.Diagnostics.Process process = new System.Diagnostics.Process();
    System.Diagnostics.ProcessStartInfo startiNFO = new  System.Diagnostics.ProcessStartInfo();

    startiNFO.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
    startiNFO.FileName = "cmd.exe";
    startiNFO.Arguments = "/C ipconfig";
    startiNFO.UseShellExecute = false;

    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardInput = true;

    process.StartInfo = startiNFO;

    process.Start();

    string outp = process.StandardOutput.ReadToEnd();
    process.WaitForExit();

    MessageBox.Show(outp);
}  

如何修复它？这是我的原始代码。

private void button1_Click(object sender, EventArgs e)
{
    System.Diagnostics.Process process = new System.Diagnostics.Process();
    System.Diagnostics.ProcessStartInfo startiNFO = new  System.Diagnostics.ProcessStartInfo();

    startiNFO.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
    startiNFO.FileName = "cmd.exe";
    startiNFO.Arguments = "/C ipconfig";
    startiNFO.UseShellExecute = false;

    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardInput = true;

    process.StartInfo = startiNFO;

    process.Start();

    string outp = process.StandardOutput.ReadToEnd();
    process.WaitForExit();

    MessageBox.Show(outp);
}

而不是

process.WaitForExit（）这样做

函数的完整代码如下所示

private void button1_Click(object sender, EventArgs e)
{
    System.Diagnostics.Process process = new System.Diagnostics.Process();
    process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
    process.StartInfo.FileName = "cmd.exe";
    process.StartInfo.Arguments = "/C ipconfig";
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.CreateNoWindow = true;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardInput = true;
    process.Start();
    string q = "";
    while(!process.HasExited)
    {
        q += process.StandardOutput.ReadToEnd();
    }
    label1.text = q;
    MessageBox.Show(q);
} 

我可以将q分配给label1.text吗？字符串outp=process.StandardOutput.ReadToEnd（）；应该移除吗？好的。谢谢。我会尝试并回复您。System.dll中发生类型为“System.InvalidOperationException”的未处理异常。其他信息：StandardOut尚未重定向或进程尚未启动。我现在想做什么？
