working with the selected DataGridView row in C#

is there a way to cast/convert the currently selected Row in a datagridview to a custom Object?

For example, I'm trying to cast the selected row to an object of type Client, however, I am unable to do so using this method.

DataGridViewSelectedRowCollection rows = dgvClient.SelectedRows;
foreach (DataGridViewRow r in rows)
{
    DataRow myRow = (r.DataBoundItem as DataRowView).Row;
    Client current = (Client)myRow;
}

No, because DataRow has no relation to Client - i.e., Client is not derived from DataRow.
Edit: I stand corrected, you can provide an explicit method of casting as @Anand explains. I would recommend this if the Client source is inaccessible. Otherwise ...

I had a project in VB.Net that used a List as the data source for a DataGridView. What was interesting is that I was able to cast the selected row to SomeEntity.

What I recommend is provide a constructor, in this case for Client, that accepts a DataRow as a parameter. Assign values from the row and be done with it:

Client current = new Client(myRow);

You can also use implicit and explicit operator for eg

class Client
{
   public static explicit operator Client(DataRow dr)
   {
      // code to convert from dr to Client
   }
}

Client current = (Client)myRow;

similarly you could overload implicit. With implicit operator you the conversion would take automatically with out casts
