Is it possible to have savefiledialog () in windows console applications

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Diagnostics
{
    class Program
    {
        static void Main(string[] args)
        {
            string filename = null;
            using (SaveFileDialog sFile = new SaveFileDialog())
            {
                sFile.Filter = "Text (Tab delimited)(*.txt)|*.txt|CSV (Comma separated)(*.csv)|*.csv";
                if (sFile.ShowDialog() == DialogResult.OK)
                {
                    filename = sFile.FileName;
                    WriteRegKey(diagnostic, filename);
                }

            }
        }
    }
}

I get the error: Could not find the type or namespace name "SaveFileDialog" (are you missing a using directive or an assembly reference?)

I tried to add a namespace System.Windows.Forms

but I couldn't.

You need to add an assembly reference System.Windows.Forms

.

Also, you must add an attribute STAThread

to the entry point method in your application.



[STAThread]
private static void Main(string[] args)
{
    using (SaveFileDialog sFile = new SaveFileDialog())
    {
        sFile.ShowDialog();
    }

    Console.ReadKey();
}

But honestly, this is a terrible idea . The console application should not have any other interface than the console itself. As the namespace suggests SaveFileDialog

, SaveFileDialog

should only be used for Forms

.

You might find it easier to reverse the problem and have a Windows Forms application with a console. To do this, create a Windows Forms Application in Visual Studio. Delete the default form. Open program.cs and delete the code that is trying to create the window and replace it with your console application code.

Now the trick is that you need to manually create the console. You can do it with this helper class:

public class ConsoleHelper
{
    /// <summary>
    /// Allocates a new console for current process.
    /// </summary>
    [DllImport("kernel32.dll")]
    public static extern Boolean AllocConsole();

    /// <summary>
    /// Frees the console.
    /// </summary>
    [DllImport("kernel32.dll")]
    public static extern Boolean FreeConsole();
}

Now at the beginning of your program (before you try to start Console.Writeline) call



ConsoleHelper.AllocConsole();

And at the very end of your program call

ConsoleHelper.FreeConsole();

You now have a console application that can create WinForms dialogs, including SaveFileDialog.

You need to add a reference to System.Windows.Forms to the project itself, not the source file. Right-click the project icon in the Solution Explorer toolbar and select "add link".

You have not imported the System.Windows.Forms namespace into your code.

You need to add a link to System.Windows.Forms from the Add Link dialog . Then call the namespace using System.Windows.Forms (no quotes) and create an object of the SaveFileDialog class .
