### 一、单个参数传递 ###

1.调用外部程序，并拼接参数注意用空格分隔

[DllImport("kernel32.dll")]
    public static extern int WinExec(string exeName, int operType);
    
    WinExec("E:\\VSWorkspace\\ConsoleApp2\\bin\\Debug\\netcoreapp2.2\\win10-x64\\ConsoleApp2.exe hello", 1);

2.子程序接收参数

static void Main(string[] args)
            {
                if (args.Length > 0)
                {
                    string a = args[0].Trim();
                    File.AppendAllText(@"E:\Test\Log.txt", a + " " + DateTime.Now + "\r\n");
                    Console.WriteLine(a + " " + DateTime.Now);
                }
                else
                {
                    File.AppendAllText(@"E:\Test\Log.txt", DateTime.Now + "\r\n");
                }
            }

                }
            }
