Question

using microsoft visuals studio c# 2017

Your "goal" is to create a soccer team registration program.

This is an individual assignment.

Your program should:

1. Ask the coach to select a team from a list (maybe listbox or radio buttons).

1. Accept athlete names from the "coach". There can be up to twelve athletes on a team. You can do this many ways, for example, have twelve textboxes to accept the information. However, after you received the information from the coach, make the boxes disappear (visibility property set to "false" for each box).

2. As the athlete names are entered (or after they are entered), they should appear in a listbox (you will need to use the "add" function of the listbox to place them in the box).

3. After all the players are entered and show up in the listbox, the program should allow the coach to fix any problems. The easiest way to do this is allow the coach to respond, "yes" or "no" that the roster is correct (could use radio buttons, or textbox). If the coach answers "no", you can just empty out the listbox and go back to requesting all the player again.

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new Windows Forms Application in C# is created using Visual Studio 2017 with name "soccerTeamRegistration".This application contains a form with name "Form1.cs".Below are the files associated with form1.

1.Form1.cs[Design]

2.Form1.Designer.cs

namespace soccerTeamRegistration

protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
