Getting model property using custom field names

I have a model with properties like this

[Display(Name = "Option Value 1")]
public string option_value1;
[Display(Name = "Option Value 2")]
public string option_value2;
[Display(Name = "Option Value 3")]
public string option_value3;
[Display(Name = "Option Value 4")]
public string option_value4;

...
...
[Display(Name = "Option Value n")]
public string option_valuen;

And I want to do something in views like

for (i = 0;i < n; i++) {
if (Model.getProperty("Option_Value"+i) != null) 
{
then display "Option_Value"+i
}

I can do it very smooth in cakephp, is that possible in ASP.NET MVC too?

Another way to do it, if you can't use an array, is to use weakly typed versions of HtmlHelpers :

@for (i = 0; i < n; i++)
{
     @Html.Display("option_value" + i)
}

You can replace Display with Editor if you want a textbox for edition purpose.

Yes, it's possible by using an array. Instead of creating a separate property for each of the options, you should have one property in your model:

public string[] Options { get; set; }

Then you will be able to loop through it and access the options with an index.

When creating inputs for that string, you have to use a for loop with an index to get MVC to generate the right id and name attributes of the inputs:

@for(int i = 0; i < Model.Options.Length)
{
  @Html.EditorFor(m => Model.Options[i])
}
