如何在 C# 中逐行读取 CMD output 结果

Question

I want to open the.bat file and for that i am using cmd and and gave input for arguments and at the end i receive whole output results but i want to get just last command output results so please guide me if anyone have any solution.

using System;
using System.Diagnostics;
using System.Text;

namespace ConsoleApp
{
    class Program
    {
        private static StringBuilder output = new StringBuilder();
        private static System.Diagnostics.Process standalone = new System.Diagnostics.Process();

        static void Main()
        {
            StartStandalone();
            StartProcess();
        }

        private static void StartProcess()
        {
            try
            {
                Process process = new Process();
                process.StartInfo.FileName = "cmd.exe";
                process.StartInfo.CreateNoWindow = false;
                process.StartInfo.RedirectStandardInput = true;
                process.StartInfo.RedirectStandardOutput = true;
                process.StartInfo.UseShellExecute = false;
                process.Start();

                process.StandardInput.WriteLine("C:\\Users\\aali\\EAP-7.2.0\\bin\\Jboss-cli.bat");
                process.StandardInput.WriteLine("connect");
                process.StandardInput.WriteLine("deployment-info");
                process.StandardInput.Flush();
                process.StandardInput.Close();

                String output = "";
                while (!process.StandardOutput.EndOfStream)
                {
                    string line = process.StandardOutput.ReadLine();
                    if (line.Contains("RUNTIME-NAME"))
                    {
                        output += line + "\r\n" + process.StandardOutput.ReadLine() + "\r\n";
                    }

                }

                Console.WriteLine(output);
                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception Occurred :{0},{1}", ex.Message, ex.StackTrace.ToString());
                Console.ReadLine();
            }
        }

        private static void StartStandalone()
        {
            standalone.StartInfo.FileName = "C:\\Users\\aali\\EAP-7.2.0\\bin\\standalone.bat";
            standalone.Start();
        }
    }
}

您已经在读取循环中的每一行，因此一个简单的解决方案是将每一行分配给一个名为 lastLine 的变量，并且在循环完成之前不对该变量执行任何操作。

当然，这不是很有效，但需要对您的代码进行最少的更改。

string lastLine = "";

while (!process.StandardOutput.EndOfStream) 
{
    lastLine = process.StandardOutput.ReadLine();
}

//lastLine will now contain the value of the last line of the output
Console.WriteLine($"Last Line = {lastLine}");
