如何在消息框中写入字典的内容？

Question

我正在使用Visual Studio C#,我有一个带有一些记录的"string-string"Dictionary变量,例如:

{Apartment1},{Free}

{Apartment2},{Taken}

等等...

如何在消息框中写这个,以便显示如下内容:

Apartment1 - Free

Apartment2 - Taken

等等...

重要的是每条记录都在消息框中的新行内.

您可以遍历字典中的每个项目并构建一个字符串,如下所示:

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);
