將C＃轉換爲VB.net不會編譯<param name =「x」

Question

我想不出如何將此代碼從C＃轉換爲VB.net。它說 - 在下面的調用代碼中沒有爲參數'y'指定參數。

有什麼建議嗎？

感謝

調用代碼：

list.Sort(Utility.CompareContactListsBySortOrder) - error here in VB 

CODE：

/// <summary> 
    /// Defines the compare criteria for two Contact List instances 
    /// </summary> 
    /// <param name="x">Contact List to be compared</param> 
    /// <param name="y">Contact List to be compared</param> 
    /// <returns></returns> 
    public static int CompareContactListsBySortOrder(ContactList x, ContactList y) 
    { 
     if (x.SortOrder.HasValue && y.SortOrder.HasValue) 
     { 
      return x.SortOrder.Value.CompareTo(y.SortOrder.Value); 
     } 

     return 0; 
    }

Answer 1

list.Sort(AddressOf Utility.CompareContactListsBySortOrder) 

在VB中，您使用AddressOf運算符來獲取創建委託的方法地址。在C＃中，您只需指定方法名稱即可。

Answer 2

你需要將其更改爲： list.Sort（AddressOf Utility.CompareContactListsBySortOrder）
