如何将一个变量值从控制台应用程序传递到C#(visualstudio)中的windows窗体应用程序

Question

我正在做一个项目，在这个项目中，我必须将控制台应用程序项目中的变量数据发送到windows窗体应用程序(我必须将这些数据写入文本框(。我试图将变量val传递到我的表单，下面的代码是我试图做的，但传递的值(windows表单中的num变量(是零而不是1(控制台应用程序中的serial.val作为参数传递，然后我调用表单(。

有人能帮我吗？

这是我的windows表单代码：

using System;

//private static int temp;

// private static int num;

public Serial_comm_1(int num)
{
InitializeComponent();
string Port_Name = "COM3";    // Store the selected COM port name to "Port_Name" varaiable
int Baud_Rate = 9600; // Convert the string "9600" to int32 9600
COMport = new SerialPort(Port_Name, Baud_Rate);
COMport.Parity = Parity.None;
COMport.StopBits = StopBits.One;
COMport.DataBits = 8;
COMport.Handshake = Handshake.None;
COMport.RtsEnable = true;
COMport.DtrEnable = true;
TextBox_Transmit_Data.Text = num.ToString();
//try to open the port 
#region  
try
{
COMport.Open();
textBox_System_Log.Text = "";
}
catch (UnauthorizedAccessException SerialException) //exception that is thrown when the operating system denies access 
{
MessageBox.Show(SerialException.ToString());
textBox_System_Log.Text = Port_Name + Environment.NewLine + Baud_Rate;
textBox_System_Log.Text = textBox_System_Log.Text + Environment.NewLine + SerialException.ToString();

COMport.Close();
}
catch //Any other ERROR
{

COMport.Close();

}
private void Button_Transmit_Data_Click(object sender, EventArgs e)

int Baud_Rate = 9600; // Convert the string "9600" to int32 9600
string Data = TextBox_Transmit_Data.Text;                             //Store the string in Textbox to variable "Data"          
COMport.ReadTimeout = 3500; //Setting ReadTimeout =3500 ms or 3.5 seconds
Console.WriteLine(COMport.IsOpen);
COMport.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);
//Program1 prog = new Program1();
//If we are able to open the port 
if (COMport.IsOpen == true)
{
COMport.WriteLine(Data);                // Send Data
textBox_System_Log.Text = Port_Name + Environment.NewLine + Baud_Rate;
textBox_System_Log.Text = textBox_System_Log.Text + Environment.NewLine + Data + "  Written to Port" + Environment.NewLine;
}
else
{

MessageBox.Show("Unable to Write to COM port ");
COMport.Close();
}
}
private void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
SerialPort sp = (SerialPort)sender;
indata = sp.ReadLine();
this.Invoke(new EventHandler(display_data_event));
}
private void display_data_event(object sender, EventArgs e)

String time = Datetime.Hour + ":" + Datetime.Minute + ":" + Datetime.Second;

{
}
private void textBox_Received_Data_TextChanged(object sender, EventArgs e)

private void TextBox_Transmit_Data_TextChanged(object sender, EventArgs e)

这是我的控制台应用程序的踪迹：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WindowsFormsApplication2;
using System.Windows.Forms;

namespace ConsoleApplication1
{
class Program1
{
private int val;
public int Val
{
get { return val; }
set { val = value; }
}
static void Main(string[] args)
{
Program1 serial = new Program1();
serial.Val = 1;
System.Windows.Forms.Application.Run(new Serial_comm_1(serial.Val));
//Serial_comm_1 serial_form1 = new Serial_comm_1(serial.Val);
}
}
}

Answer 1

从您的应用程序启动另一个应用程序：

// Create a new Process
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo = new System.Diagnostics.ProcessStartInfo();
process.StartInfo.FileName = @"C:ProjectsTemp912binDebugTemp912.exe";
process.StartInfo.Arguments = "Test Argument";
process.StartInfo.UseShellExecute = false;
process.Start();

现在从你的Windows窗体应用程序，修改主要方法：

using System;
using System.Windows.Forms;
namespace Temp912
{
static class Program
{
[STAThread]
static void Main(string[] args)
{
string arg1 = "";
if ((args != null) && (args.Length > 0))
{
arg1 = args[0];
MessageBox.Show("Arg1: " + arg1, "Arg App Started With Parameter");
}
else
{
MessageBox.Show("Arg1: N/A", "Arg App Started Without Parameter");
}
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}

如果您需要将参数值传递到主窗体，请在窗体上公开一个或多个属性，并在启动窗体之前设置值。

按问题编辑：

表单代码

公共字符串MyProperty｛get；set；｝//将数据类型更改为int或任何

Than在Program.cs中，而不是：

Application.Run(new Form1());

这样做：

// create an instance of your form
Form1 form1 = new Form1();
// set the property or properties
form1.MyProperty = arg1;

然后呼叫：

// this is should work, I didn't test this like the other code
Application.Run(form1);
