         用來搜尋反映之索引實例屬性的名稱會根據語言和套用至屬性的屬性而有所不同。
        
        
         
          在 Visual Basic 中，屬性名稱一律用來搜尋具有反映的屬性。 您可以使用
          
           Default
          
          關鍵字讓屬性成為預設的索引屬性，在此情況下，您可以在存取屬性時省略名稱，如本範例所示。 您也可以使用屬性名稱。
         
        
        
         
          在 C# 中，索引實例屬性是稱為索引子的預設屬性，而且在程式碼中存取屬性時永遠不會使用名稱。 根據預設，屬性的名稱是
          
           Item
          
          ，而且當您使用反映搜尋屬性時，必須使用該名稱。 您可以使用
          
           IndexerNameAttribute
          
          屬性來為索引子提供不同的名稱。 在這個範例中，名稱為
          
           IndexedInstanceProperty
          
          。
         
        
        
         
          在 C++ 中
          
           default
          
          ，規範可用來將索引屬性設為預設索引屬性， (類別索引子) 。 在此情況下，屬性的名稱預設為
          
           Item
          
          ，而且當您搜尋具有反映的屬性時，您必須使用該名稱，如本範例所示。 您可以使用
          
           IndexerNameAttribute
          
          屬性在反映中為類別索引子提供不同的名稱，但您無法使用該名稱來存取程式碼中的 屬性。 在程式碼和反映中，都會使用其名稱來存取不是類別索引子的索引屬性。
