MVC Razor View - Using Model in .EditorFor() and for in String.Format()

Question

<td>@Html.EditorFor(Model => Model.Loan)</td>

I have that in the beginning of the view, and then after that, I have a statement like

The interest rate for the loan is @String.Format("{0:c}", Model.Interest).

It gives me error "'Model' conflicts with the declaration 'System.Web.Mvc.WebViewPage.Model'"

I also tried

The interest rate for the loan is @String.Format("{0:c}", Model => Model.Interest).

It errored "Cannot convert lambda expression to type 'object[]' because it is not a delegate type"

If I remove the EditorFor, it doesn't error for the next statement.

Is there any way I can do both, other than adding the model to the ViewBag.

The argument name in the lambda expression is conflicting with the existing Model property.

You need to use a different argument name, such as @Html.EditorFor(m => m.Loan)

Thanks, that works. I thought the @model at the top of the view page is declaration of the variable.

I remember seeing "x => x.Property" example as well, if that works, does this mean all Lambda expression refers to Model? Or all undeclared variable using like m or x, would refer to the model?

Neither. A lambda expression is a function that takes an argument named x or m or whatever. The name of the argument is totally irrelevant. Most MVC helper methods take lambda expressions that receive the model as their parameter.
