please share the code where you assign the parameters using for each

The error means you cannot loop over whatever objects you are trying to because they don't implement IEnumerator. But since you did not show us the code that actually creates the error I'm not sure what you want us to do.

You can't iterate over the properties of an object with a foreach or even a for loop - or you can, but it takes a good deal of work with reflection, and it creates code that is hard to maintain.
To use foreach the target object must e an instance of a class that implements iEnumerable or iEnumerable<T> - a Collection of other objects such as a List<T> or even an ArrayList. You can't just plonk an instance of a "random" class there and expect it to know that you want to perform the same task on each property.

If you want to assign parameters, you really should do it one by one, not try to work with a loop - you will get maintenance problems if you don't.

public class BookRequest : IEnumerable<KeyValuePair<string, object>>
{
public string EndUserIp { get; set; }
public string TokenId { get; set; }
public string TraceId { get;set; }
public int ResultIndex { get; set; }
public string HotelCode { get; set; }
public string HotelName { get; set; }
public string GuestNationality { get; set; }
public int NoOfRooms { get; set; }
public string ClientReferenceNo { get; set; }
public Boolean IsVoucherBooking { get; set; }

public IEnumerator<KeyValuePair<string, object>> GetEnumerator()
{
return this.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance).ToDictionary(p => p.Name, p => p.GetGetMethod().Invoke(this, null)).GetEnumerator();
}

IEnumerator IEnumerable.GetEnumerator()
{
throw new NotImplementedException();
}
}

now for iteration

var obj = new MyModel();
foreach(var kv in obj)
Console.WriteLine(kv.Key + ": " + kv.Value ?? "null");

Solution 3

Please using the typecast concept.
e.g:-
string[] arr = { "Anil", "Ali", "Akram", "Mahadev", "Lijo" };
TempData["var4"] = arr;

@{
foreach(var item in (string[])TempData["var4"])
{

@item

}
}

Foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'getenumerator
