How to delete a object from database in ASP.NET MVC?

Question

I want to delete a object from my database using ASP.NET MVC. I have connected to the database with Entity Framework. I have made this code for my controller named Delete.

// DELETE-POST [HttpPost] [ValidateAntiForgeryToken] public IActionResult Delete(int? id) { var obj = _db.Project.Find(id); if(obj == null) { return NotFound(); } _db.Project.Remove(obj); _db.SaveChanges(); return RedirectToAction("Index"); }

Then I created a button with a link to my controller

<a asp-action="Delete" class="btn btn-danger btn-lg text-white w-30">Delete</a>

I had expect that my object should disappear. But I get an issue when I press the button. It only returns a blank site with a message that the site does not work.

Does anyone have any ideas why?

You have to add Id to your ancor tag. Try to use this:

<a asp-controller="...Controller" asp-action="Delete" asp-route-id="@Model.Id" class="btn btn-danger btn-lg text-white w-30"> Delete</a>

You need to pass id from view.

<a asp-action="Delete" asp-route-id="@Model.Id" class="btn btn-danger btn-lg text-white w-30">Delete</a>
