如何通過lambda將匿名屬性傳遞給泛型函數？

Question

我想通過使用lambda的匿名屬性到一個通用函數並在那裏訪問它。
以及如何訪問裏面的屬性。

using (CommentsRepository commentsRepository = new CommentsRepository()) 
{ 
    var comments = commentsRepository.GetAllComments(); 

    Foo<Comment>(comments, 0,com=>com.ID); //Comment is an EF entity 
} 

public static void Foo<TObject>(IEnumerable<TObject> list, int iCurID, <Func<TObject, TProperty> property) where TObject : class 
{  
    foreach (var cat in list.Where(/*How to access the property*/==iCurID) 
    { 
      int x = cat.property; 
    } 
} 

Answer 1

您只要致電委託：

public static void Foo<TObject> 
    (IEnumerable<TObject> list, 
    int iCurID, 
    Func<TObject, int> propertySelector) where TObject : class 
{  
    foreach (var cat in list.Where(x => propertySelector(x) == iCurID)) 
    { 

    } 
} 

注意，我只好委託的類型更改爲Func<TObject, int>否則你無法iCurID進行比較。
