请高手指点C# new Process出异常
本人想用C#执行命令行，执行Process process = new Process();时就会出异常
BasePriority = “process.BasePriority”引发了“System.InvalidOperationException”类型的异常
ExitCode = “process.ExitCode”引发了“System.InvalidOperationException”类型的异常
ExitTime = “process.ExitTime”引发了“System.InvalidOperationException”类型的异常
......
process的属相
貌似都异常了，哪位高手给指点下为啥。
代码如下：
private void executeCommand(string command)
{
Process process = new Process();
process.StartInfo.FileName = "cmd.exe";
//从 Process.StandardInput流中读取
process.StartInfo.RedirectStandardInput = true;
//写入 Process.StandardOutput流中
process.StartInfo.RedirectStandardOutput = true;
//错误输出写入 Process.StandardError 流中
process.StartInfo.RedirectStandardError = true;
//不显示界面
process.StartInfo.CreateNoWindow = true;
//不使用操作系统外壳程序启动进程
process.StartInfo.UseShellExecute = false;
process.StandardInput.WriteLine(command);
process.StandardInput.WriteLine("exit");
MessageBox.Show(process.StandardOutput.ReadToEnd());
}
process.StartInfo.UseShellExecute = false;
process.Start();//这句是我加的
process.StandardInput.WriteLine(command);
process.StandardInput.WriteLine("exit");
MessageBox.Show(process.StandardOutput.ReadToEnd());
[解决办法]
protected void Page_Load(object sender, EventArgs e)
{
executeCommand("notepad");
}
private void executeCommand(string command)
{
Process process = new Process();
process.StartInfo.FileName = "cmd.exe";
//从 Process.StandardInput流中读取
process.StartInfo.RedirectStandardInput = true;
//写入 Process.StandardOutput流中
process.StartInfo.RedirectStandardOutput = true;
//错误输出写入 Process.StandardError 流中
process.StartInfo.RedirectStandardError = true;
//不显示界面
process.StartInfo.CreateNoWindow = true;
//不使用操作系统外壳程序启动进程
process.StartInfo.UseShellExecute = false;
//这句话少了
process.Start();
process.StandardInput.WriteLine(command);
process.StandardInput.WriteLine("exit");
Response.Write(process.StandardOutput.ReadToEnd());
}
