    You have some invalid javascript over there.

    First start by fixing your view model so that you have a compiling C# code (you were missing a property name):

    public class StudentSearchResult 
    {
        public IEnumerable Students { get; set;}
    }
    

    Then assuming your controller actions sends a JSON result to the client (this ensures that the view model is properly JSON encoded and that the application/json response content type header is sent):

    [HttpPost]
    public ActionResult StudentSearchResult(/*other stuff I send here, */ string[] studentNames)
    {
        StudentSearchResult model = ... //stuff here to populate your view model
        return Json(model);
    }
    

    you could easily iterate on the client using the $.each() function:

    var studentNames = ['name1', 'name2'];
    $.post('/Students/StudentSearchResult', studentNames, function(result) {
        var students = result.Students;
        $.each(students, function() {
            alert('FirstName: ' + this.FirstName + ' LastName:' + this.LastName);
        });
    });
    

    or even a plain ol' for loop if you prefer:

    $.post('/Students/StudentSearchResult', studentNames, function(result) {
        var students = result.Students;
        for (var i = 0; i < students.length; i++) {
            var student = students[i];
            alert('FirstName: ' + student.FirstName + ' LastName:' + student.LastName);
        }
    });
    

    UPDATE:

    It looks like I have I made a mistake by believing that you were performing an AJAX request. Instead what you need is access the model properties in javascript. Here's how this could be done:

    @model StudentSearchResult
