How to implement this ?

Make a form with a Label instance for the prompt ("Enter value") and a
TextBox instance for the user input, a button for "OK" and optionally a
"Cancel" button. Make sure the buttons are configured for the correct
DialogResult (set their DialogResult property as desired).

Instantiate the form, call ShowDialog() on it, if the return value is
DialogResult.OK, process the Text property of the TextBox instance as
your entered value.

Wrap all of the above in a method that does all of the work and simply
returns the string value obtained from the Text property of the TextBox.
Don't forget to dispose your form instance before returning.

Pete,

Can you provide example code please ?
Or maybe some VB assembly contains such function ?

Or, one could set a reference to Microsoft.VisualBasic.dll assembly and
call the InputBox method on the Interaction class in the
Microsoft.VisualBasic namespace.

Some don't like the idea of loading Microsoft.VisualBasic.dll, but it's
there to use if one wants (and I assume the OP wanted this, as he used the
name of the method in VB which does the same thing).

I wrote an article on how to create an inputbox in C#...it's pretty simple.

Why you re-invented wheel !?

Isn't it simpler to use

string res = Interaction.InputBox("prompt", "caption", "defaultresponse",

0, 0);



from VisualBasic.dll as Nicolas recommends?

Andrus.

Thank you.
I plan to use MS ReportViewer which loads VisualBasics.dll anyway, so no
difference.

I tried

Interaction.InputBox("prompt", "caption", "defaultresponse", 0, 0);

but window appears in the left upper corner.

How to force window to be centered in screen ?

Andrus,

Well, you are specifying the top left of the screen using 0 and 0 for
the x and y parameters. Use -1, and it should center the input box.
