在聲明中添加鍵/值到詞典

Question

今天很簡單，我想。在C＃中，它的：

Dictionary<String, String> dict = new Dictionary<string, string>() { { "", "" } }; 

但是在vb中，以下不起作用。

Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) (("","")) 

我很確定有一種方法可以在聲明中添加它們，但我不知道如何。是的，我想在聲明中添加它們，而不是其他時間。 :)所以希望這是可能的。感謝大家。

我也試過：

Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) ({"",""}) 

而且......

Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) {("","")} 

而且......

Public dict As Dictionary(Of String, String) = New Dictionary(Of String, String) {{"",""}} 

Answer 1

這是可能在VB.NET 10：

Dim dict = New Dictionary(Of Integer, String) From {{ 1, "Test1" }, { 2, "Test1" }} 

不幸的是IIRC VS 2008使用VB.NET 9編譯器不支持此語法。

而對於那些可能會感興趣，這裏的幕後發生了什麼（C＃）：

Dictionary<int, string> VB$t_ref$S0 = new Dictionary<int, string>(); 
VB$t_ref$S0.Add(1, "Test1"); 
VB$t_ref$S0.Add(2, "Test1"); 
Dictionary<int, string> dict = VB$t_ref$S0; 

Answer 2

有沒有構造採取KeyValuePair的字典。

Answer 3

它是大同小異，使用From關鍵字：

Dim d As New Dictionary(Of String, String) From {{"", ""}} 

然而，這需要該語言的版本10，可在VS2010中獲得。

Answer 4

下面是一個很酷的翻譯：你也可以有一個字符串和字符串數組的泛型字典。

C＃：

private static readonly Dictionary<string, string[]> dics = new Dictionary<string, string[]> 
     { 
      {"sizes", new string[] {"small", "medium", "large"}}, 
      {"colors", new string[] {"black", "red", "brown"}}, 
      {"shapes", new string[] {"circle", "square"}} 
     }; 

VB：

Private Shared ReadOnly dics As New Dictionary(Of String, String()) From { _ 
{"sizes", New String() {"small", "medium", "large"}}, _ 
{"colors", New String() {"black", "red", "brown"}}, _ 
{"shapes", New String() {"circle", "square"}}} 

酷HAA :)
