I want to understand the lambda expression in @Html.DisplayFor(modelItem => item.FirstName)

Question

I’m fairly new at C# and MVC and have used lambdas on certain occasions, such as for anonymous methods and on LINQ.

Usually I see lambda expressions that look someth

Answer 1

i think it's about the foreach loop. example:

@foreach(var item in model) 
{ 
  
     @html.displayfor(model => item.firstName) 
      
}

var item needs to be used because each item in the sequence is an anonymous type. model => item.firstName means (input parameter) => expression. you can't use the input parameter because we store the current "item" in item.
