     c#  for Vs2013 for Express

C# Program :

using EPDM.Interop.epdm;

...

IEdmFile5 aFile = default(IEdmFile5);

.....

....

try

  {

       aFile.UnLockFile(this.Handle.ToInt32(), "Updated Vendor", 8, null);

  }

catch (System.Exception ex)

  {

        vault1.MsgBox(0, ex.Message, EdmMBoxType.EdmMbt_OKOnly, "");

  }

My Question:  Rebuild Project have Error --->> EPDM.Interop.epdm.IEdmFile5 not include 'UnLockFile'

錯誤    1    'EPDM.Interop.epdm.IEdmFile5' 不包含 'UnLockFile' 的定義，也找不到擴充方法 'UnLockFile' 來接受型別 'EPDM.Interop.epdm.IEdmFile5' 的第一個引數 (您是否遺漏 using 指示詞或組件參考?)  

Thank You
