Form closing immediately after show in C#

Question

I'm having a bit of trouble with a form it's a form designed with the form designer and my project, it closes immediately upon showing. Here's the relevant code:

namespace Grapher
{
    class Program
    {
        static void Main(string[] args)
        {
            InputForm mainForm = new InputForm();
            mainForm.Show();
        }
    }
}

I've tried to put in a for(;;) but that just makes the for hang, I'm probably doing something silly, very new to C#.

Thanks in advance.

Answer 1

Use Application.Run() :

namespace Grapher
{
    class Program
    {
        static void Main(string[] args)
        {
            Application.Run(new InputForm());
        }
    }
}

Answer 2

Do:

Application.Run(mainForm);

This will start the UI properly.

Answer 3

You need to call Application.Run(new InputForm()) .

Your code simply shows the form, then the program reaches its end (the end of the Main function) and terminates.

Answer 4

使用form.ShowDialog()而不是form.Show()解决了这个问题
