You can't always cast any collection type into any other collection. In terms of when the the compiler checks casting, check out this post on [Compile-time vs runtime casting](https://stackoverflow.com/a/4499558/1366033)

However, you can easily produce a `BindingList` from an enumerable by doing some of the plumbing yourself. Just add the following Extension Method onto any Enumerable type to  convert the collection into a BindingList.


**C#**:



    static class ExtensionMethods
    {
        public static BindingList<T> ToBindingList<T>(this IEnumerable<T> range)
        {
            return new BindingList<T>(range.ToList());
        }
    }

    //use like this:
    var newBindingList = (from i in new[]{1,2,3,4} select i).ToBindingList();

**VB**:



    Module ExtensionMethods
        <Extension()> _
        Public Function ToBindingList(Of T)(ByVal range As IEnumerable(Of T)) As BindingList(Of T)
            Return New BindingList(Of T)(range.ToList())
        End Function
    End Module

    'use like this:
    Dim newBindingList = (From i In {1, 2, 3, 4}).ToBindingList()

I am new with Linq and I would like to sort some data that are in the BindingList. Once I did my Linq query, I need to use back the BindingList collection to bind my data.


     var orderedList = //Here is linq query
     return (BindingList<MyObject>)orderedList;

This compiled but fails in execution, what is the trick?
