[英]Calling cmd.exe using Process in C# hanging
I am trying to get the standard out from cmd.exe (testing "DIR" command), and put it into a text box. 我正在尝试从cmd.exe(测试“ DIR”命令)中获取标准,并将其放入文本框中。 However, whenever I start the process the program hangs (no button presses). 但是,无论何时启动该程序,程序都会挂起(不按任何按钮)。
private void cmd_test()
{
Process pr = new Process()
{
StartInfo = {
FileName = "cmd.exe",
UseShellExecute = true,
CreateNoWindow = true,
RedirectStandardOutput = true,
RedirectStandardInput = true,
RedirectStandardError = true,
}
};
pr.Start();
pr.StandardInput.WriteLine("DIR");
TextBox1.Text = pr.StandardOutput.ReadToEnd();
}
I have also tried Arguments = "DIR"
in the StartInfo block instead of WriteLine. 我还尝试了StartInfo块而不是WriteLine中的Arguments = "DIR"
。
How do I properly send a command to cmd.exe, without it hanging? 我如何正确地将命令发送到cmd.exe,而不将其挂起?
Here you go: 干得好:
using (var p = new Process())
{
p.StartInfo.CreateNoWindow = true;
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments = "/C dir";
p.Start();
var output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
richTextBox1.Text = output;
}
