You're showing us your model in TypeScript. First you've to convert that model to a .net class. Which would result into something like:
public class Teacher
{
public string Id { get; set; }
public string FullName { get; set; }
public string Email { get; set; }
public string Profile { get; set; }
}
Next you've to create a list or array of this model, since you said you had an array in JavaScript I will use it as well. So you will get:
Teacher[] teachers = new Teacher[5];
Next you want to set a value in this array (there are multiple ways how you can do this), one way of doing this is:
teachers[0] = new Teacher
{
Id = "1",
FullName = "Full Name",
Email = "[email protected]",
Profile = "Some profile information"
};
