Cannot convert from ‘method group’ to ‘object’

I want to add a button that triggers the action on the Controller inside the razor CSHTML for my ASP.NET project.

Below is the section of the code

   <div class="col-12 col-md-12 col-lg-6">

   </div>

   <button type="submit" class="btn btn-warning w-100" 
   asp-action="update" asp-route-id="edit" asp-route-id2="@item.Value">
   <i class="fas fa-plus"></i>Update Template</button>

And the error I am getting is cannot convert from method group to object.

Method 1

If you want to trigger the action on the Controller with HttpGet,you can use <a></a> tag:

<a asp-action="update" asp-route-id="edit" asp-route-id2="@item.Value"><i class="fas fa-plus"></i>Update Template</a>

If you want to trigger the action on the Controller with HttpPost,you can add a form outside button:

 <form method="post">
        <button type="submit" class="btn btn-warning w-100"
                asp-action="update" asp-route-id="edit" asp-route-id2="@item.Value">
            <i class="fas fa-plus"></i>Update Template
        </button>
    </form>

And the error I am getting is cannot convert from method group to
object.

For the error,I think it may caused by your backend code,may be somewhere you want to get an object from a method,and you forget to add ().Here is a demo:

    public class A {
        public int Id { get; set; }
        public string Name { get; set; }
    
    }
    public A returnObject()
        {
            return new A {  Id=1,Name="a"};
        }
   public void Update()
        {
            A o=returnObject;//Here you need to use A o=returnObject();
        }
