ExpandoObject を匿名型にキャストできますか?
var anoObj = new { name = "testName", email = "testEmail" };
dynamic expandoObj = new System.Dynamic.ExpandoObject();
// Here I'm populating the expandoObj with same property names/types in anonymoustype(anoObj)
// Now, how to convert this ExpandoObject to anonymoustype ?
var newObj = (typeof(anoObj)expandoObj); // This doesn't work
後で追加
// これは私のエンティティです
public class Customer
{
#region Public Properties
[ColumnAttribute(Name = "IdColumn")]
public string Id { get; set; }
[ColumnAttribute(Name = "NameColumn")]
public string Name { get; set; }
[ColumnAttribute(Name = "AddressColumn")]
public string Address { get; set; }
[ColumnAttribute(Name = "EmailColumn")]
public string Email { get; set; }
[ColumnAttribute(Name = "MobileColumn")]
public string Mobile { get; set; }
#endregion
}

var lookupService = new LookupService<Customer>();
var lookupSelection = lookupService.Select(C => new { C.Id, C.Name, C.Mobile }).Show(C => new { C.Id, C.Name}).Execute();
string sID = lookupSelection.Id;
string sName = lookupSelection.Name;
string sMobile = lookupSelection.Mobile;
この中間部分については考えないでください..それの目的は別のものです...
私の問題は、LookupExecutable クラスの Execute() メソッドにあります。TSelection 型の新しいインスタンスを作成してそれに値を割り当てる方法がわかりません。この TSelection 型は常に匿名型です。
