如何在消息框中編寫字典的內容？

Question

我在Visual Studio C＃工作，我有一些記錄一個「串線」解釋變量，例如：

{Apartment1},{Free} 

{Apartment2},{Taken} 

等等

我怎麼能寫這裏面一個消息框，以便它顯示是這樣的：

Apartment1 - Free 

Apartment2 - Taken 

等等

重要的是，每一個記錄是在消息框中新行內。

Answer 1

var sb = new StringBuilder(); 

foreach (var kvp in dictionary) 
{ 
    sb.AppendFormat("{0} - {1}\n", kvp.Key, kvp.Value); 
} 

MessageBox.Show(sb.ToString()); 

Answer 2

你可以循環儘管在字典中的每個項目，並建立一個字符串，像這樣：

Dictionary<string, string> dictionary = new Dictionary<string, string>(); 
StringBuilder sb = new StringBuilder(); 

foreach (var item in dictionary) 
{ 
    sb.AppendFormat("{0} - {1}{2}", item.Key, item.Value, Environment.NewLine); 
} 

string result = sb.ToString().TrimEnd();//when converting to string we also want to trim the redundant new line at the very end 
MessageBox.Show(result); 

Answer 3

它可以通過一個簡單枚舉的方式來完成：

// Your dictionary 
    Dictionary<String, String> dict = new Dictionary<string, string>() { 
    {"Apartment1", "Free"}, 
    {"Apartment2", "Taken"} 
    }; 

    // Message Creating 
    StringBuilder S = new StringBuilder(); 

    foreach (var pair in dict) { 
    if (S.Length > 0) 
     S.AppendLine(); 

    S.AppendFormat("{0} - {1}", pair.Key, pair.Value); 
    } 

    // Showing the message 
    MessageBox.Show(S.ToString()); 

Answer 4

string forBox = ""; 
foreach (var v in dictionary)    
    forBox += v.Key + " - " + v.Value + "\r\n"; 
MessageBox.Show(forBox); 

OR：

string forBox = ""; 
foreach (string key in dictionary.Keys) 
    forBox += key + " - " + dictionary[key] + "\r\n"; 
MessageBox.Show(forBox); 

OR：（using System.Linq;）

MessageBox.Show(String.Join("\r\n", dictionary.Select(pair => String.Join(" - ", pair.Key, pair.Value)))); 

Answer 5

是的，你可以做到這一點與下面的代碼：

Dictionary<string, string> dict= new Dictionary<string, string>(); 
StringBuilder sb = new StringBuilder(); 

foreach (var item in dict) 
{ 
    sb.AppendFormat("{0} - {1} \\r\\n", item.Key, item.Value); 
} 

string result = sb.ToString(); 
MessageBox.Show(result);
