Question

有没有办法使用C＃显示Windows弹出消息？

我的意思是使用可以在cmd中使用的windows msg.exe 程序，例如：＆＃34; msg *您好＆＃34;

PD：我知道我可以使用MessageBox.Show（）代替。但我想知道这是否可行:(

我写了两种方法来做但没有一种方法：

Process.Start("cmd.exe","/C msg * Hello");

和...

Process cmd = new Process
{
    StartInfo = new ProcessStartInfo
    {
        FileName = "cmd.exe",
        Arguments = "/C msg * Hello",
        UseShellExecute = false,
        RedirectStandardInput = true,
        RedirectStandardOutput = true,
        RedirectStandardError = true,
        CreateNoWindow = true,
        WindowStyle = ProcessWindowStyle.Hidden
    }
};
cmd.Start();

您是否尝试直接添加msg.exe？

  Process cmd = new Process
    {
        StartInfo = new ProcessStartInfo
        {
            FileName = @"msg.exe",
            Arguments = @"* /v Hello",
            WorkingDirectory = Environment.SystemDirectory;
            WindowStyle = ProcessWindowStyle.Normal
        }
    };
    cmd.Start();

我遇到了同样的问题。

这是因为项目被配置为“ AnyCPU”，但是在项目配置的“构建”选项卡中选中了“首选32位”选项。取消选中该选项，问题将消失。

编辑：个人而言，我使用以下函数根据可执行文件和OS平台（32/64位）定位二进制文件：

public static bool LocateMsgExe(out string returnedMsgPath)
{
    returnedMsgPath = null;
    string[] msgPaths = new string[] { Environment.ExpandEnvironmentVariables(@"%windir%\system32\msg.exe"),
                                     Environment.ExpandEnvironmentVariables(@"%windir%\sysnative\msg.exe") };

    foreach (string msgPath in msgPaths)
    {
        if (File.Exists(msgPath))
        {
            returnedMsgPath = msgPath;
            return true;
        }
    }

    return false;
}

并调用它：

if (LocateMsgExe(out string strMsgPath))
{
    Process.Start(strMsgPath, "* \"Hello world!\"");
}

此致

这是我的解决方案。它由一个带有列表框（lstComputers）的网页（.aspx），一个文本框（txtMessageToSend），一个用于选择包含将接收该消息的计算机的OU的下拉列表和一个按钮（btnSendMessage）组成。这是aspx.cs上btnSendMessage的代码

protected void btnSendMessage_Click(object sender, EventArgs e)
    {
        string searchbase = ddlZaal.SelectedItem.Text; //This is a dropdownlist to select an OU
        DirectoryEntry entry = new DirectoryEntry("LDAP://OU=" + searchbase + ",OU=YourOU,OU=YourSubOU," + Variables.Domain + ""); //Variables.Domain is specified in the Web.config
        DirectorySearcher mySearcher = new DirectorySearcher(entry);
        mySearcher.Filter = ("(objectClass=computer)");
        foreach (SearchResult result in mySearcher.FindAll())
        {
            DirectoryEntry directoryObject = result.GetDirectoryEntry();
            string computernaam = directoryObject.Properties["Name"].Value.ToString();
            lstComputers.Items.Add(computernaam); //This is a listbox that shows the computernames. To each computer a message is sent.
            string pingnaam = computernaam + "dns.suffix"; //Might be necessary for connecting to the computes in the domain
            string MessageToSend = txtMessageToSend.Text; //The text in this textbox will be the messagetext
            Process process = new Process();
            ProcessStartInfo psi = new ProcessStartInfo(@"C:\inetpub\wwwroot\PsExec.exe"); //Location of PsExec.exe on the webserver that hosts the web-application.
            psi.UseShellExecute = false;
            psi.RedirectStandardOutput = true;
            psi.RedirectStandardError = true;
            psi.RedirectStandardInput = true;
            psi.WindowStyle = ProcessWindowStyle.Minimized;
            psi.CreateNoWindow = true;
            psi.Arguments = "/accepteula -s -i \\\\" + pingnaam + " cmd /c msg.exe * " + MessageToSend;
            process.StartInfo = psi;
            process.Start();
        }

    }
