获取命令行输出内容的方式有传统和异步两种方式。
传统方式：
public static void RunExe(string exePath, string arguments, out string output, out string error)
{
using (Process process = new System.Diagnostics.Process())
{
process.StartInfo.FileName = exePath;
process.StartInfo.Arguments = arguments;
// 必须禁用操作系统外壳程序
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true; process.Start(); output = process.StandardOutput.ReadToEnd();
error = process.StandardError.ReadToEnd(); process.WaitForExit();
process.Close();
}
}
class Program
{
static void Main(string[] args)
{
string output;
string error;
CMD.RunExe("ping", "www.baidu.com",out output,out error);
Console.WriteLine(output +"\n"+ error);
}
}
异步方式：
/// <summary>
/// 执行一条command命令
/// </summary>
/// <param name="command">需要执行的Command</param>
/// <param name="output">输出</param>
/// <param name="error">错误</param>
public static void ExecuteCommand(string command, out string output, out string error)
{
try
{
//创建一个进程
Process process = new Process();
process.StartInfo.FileName = command; // 必须禁用操作系统外壳程序
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true; //启动进程
process.Start(); //准备读出输出流和错误流
string outputData = string.Empty;
string errorData = string.Empty;
process.BeginOutputReadLine();
process.BeginErrorReadLine(); process.OutputDataReceived += (sender, e) =>
{
outputData += (e.Data + "\n");
}; process.ErrorDataReceived += (sender, e) =>
{
errorData += (e.Data + "\n");
}; //等待退出
process.WaitForExit(); //关闭进程
process.Close(); //返回流结果
output = outputData;
error = errorData;
}
catch (Exception)
{
output = null;
error = null;
}
}
