Question

我正在构建一个简单的Windows窗体应用程序。

这很简单，在我的Windows PC上，它可以正常运行。

如果我尝试在Windows Ce设备上复制.exe和.pdb文件并尝试启动它，则会出现此错误：

File or assembly name
'System.windows.forms, Version= 2.0.0.0, Culture=neutral, PublickKeyToke= ..... or one of its dependecies, was not found.

我的应用程序有两个简单的文本框，并在.txt文件中写入文本。这是Form1.cs的代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.IO;
using System.Text;
using System.Windows.Forms;

namespace EasyManagementOrdine
{
    public partial class Form1 : Form
    {
        private const string FILE_NAME = "ESPORTAZIONE.txt";

        public List<string> listaString = new List<string>();

        public StreamWriter sw;

        public Form1()
        {
            try
            {
                InitializeComponent();
                if (File.Exists("ESPORTAZIONE.txt"))
                {
                    File.Delete("ESPORTAZIONE.txt");
                }
                this.sw = File.CreateText("ESPORTAZIONE.txt");
                //this.textQuantita.KeyPress.(new KeyPressEventHandler(this, CheckEnter));
                this.textCodiceBarre.Focus();
            }
            catch(Exception e)
            {

            }

        }

        private void codiceBarreEnter(object sender, KeyPressEventArgs e)
        {
            try
            {
                if (e.KeyChar == '\r')
                {
                    if ((!this.textCodiceBarre.Focused ? false : this.textCodiceBarre.Text.Length > 0))
                    {
                        this.textQuantita.Focus();
                    }
                }
            }
            catch (Exception exception)
            {
                Exception ex = exception;
                MessageBox.Show(string.Concat("Errore: ", ex.Message));
            }
        }

        private void quantitaEnter(object sender, KeyPressEventArgs e)
        {
            try
            {
                if (e.KeyChar == '\r')
                {
                    if ((!this.textQuantita.Focused ? false : this.textQuantita.Text.Length > 0))
                    {
                        this.salvaQuantita();
                    }
                }
            }
            catch (Exception exception)
            {
                Exception ex = exception;
                MessageBox.Show(string.Concat("Errore: ", ex.Message));
            }
        }

        private void salvaQuantita()
        {
            try
            {
                int numeroQuantita = int.Parse(this.textQuantita.Text);
                string nuovaStringa = string.Concat(this.textCodiceBarre.Text, " && ", numeroQuantita);
                this.sw.WriteLine(nuovaStringa);
                this.textCodiceBarre.Text = "";
                this.textQuantita.Text = "";
                this.textCodiceBarre.Focus();
            }
            catch (Exception exception)
            {
                Exception e = exception;
                MessageBox.Show(string.Concat("Errore: ", e.Message));
            }
        }

        private void buttonOrdine_Click(object sender, EventArgs e)
        {
            try
            {
                this.sw.Close();
                MessageBox.Show("Il file ESPORTAZIONE.txt è statp creato.", "Complimenti");
            }
            catch (Exception exception)
            {
                Exception ex = exception;
                MessageBox.Show(string.Concat("Errore: ", ex.Message));
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                Environment.Exit(0);
            }
            catch (Exception exception)
            {
                String process = Process.GetCurrentProcess().ProcessName;
                Process.Start("cmd.exe", "/c taskkill /F /IM " + process + ".exe /T");
                Exception ex = exception;
                MessageBox.Show(string.Concat("Errore: ", ex.Message));
            }
        }
    }
}

出什么问题了？

阅读评论后......

您正在使用VS2017，但2010年版本的Visual Studio不支持移动应用程序> Windows Phone OS之前的Windows Phone版本的开发 7.0。

https://docs.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2010/sa69he4t(v=vs.100)

您可能正在创建一个普通的Windows应用程序，并尝试将其复制到Windows CE，但这种方式不起作用

您渴望使用Visual Studio 2008

您将能够找到合适的模板来创建Windows CE项目...

这现在无关紧要，但请记住。.

紧凑型框架不支持MessageBox类，因为.Show(String...)是

的重载。

Show(IWin32Window, String, ...)
