};
//建立多維List關係
List<List<String>> options = new List<List<String>> {
titles,
websites
};
//新增QQBoxy資料
titles.Add("QQBoxy");
websites.Add("http://qqboxy.blogspot.com/");
//移除ChatBoxy資料
titles.Remove("ToolBoxy");
websites.Remove("http://toolboxy.blogspot.com/");
//移除第0筆資料
titles.RemoveAt(0);
websites.RemoveAt(0);
//印出資料
foreach (List<String> value in options)
{
foreach (var v in value)
{
Console.WriteLine(v);
}
}
}
}
}

結果：


說明：
C#多維List新增移除資料後印出內容。

結果：

說明：
使用Add Window方式設計WPF Confirm視窗， 主視窗可設定加入多組選項包含名稱及描述， 並在ShowDialog後的Confirm視窗產生標題、說明及選項， 最後按下確認回傳RadioButton的Option名稱。

int shortestWordLength = words.Min(w => w.Length); //Find the length of the shortest word
Console.WriteLine(shortestWord + "\n" + shortestWordLength);
}
}
}

結果：


說明：
簡單使用goes to(=>)搜尋字串長度最小值。

C# Regex Double Backslash

標題：C#使用雙反斜線表示特殊字元
C# (Main.cs)：
1
Regex solidVcg = new Regex("^\\s*solid\\svcg$");

說明：
在C#撰寫特殊字元如\s時，
若只有一個反斜線Visual Studio C#會報錯，
如下圖：

這時候必須使用雙反斜線來表示就能正常執行。

<Button Content="ADD" Height="40" HorizontalAlignment="Left" Margin="118,259,0,0" Name="btn_add" VerticalAlignment="Top" Width="100" Click="btn_add_Click" />
<Button Content="Show" Height="40" HorizontalAlignment="Left" Margin="224,0,0,12" Name="btn_show" VerticalAlignment="Bottom" Width="100" Click="btn_show_Click" />
<TextBox Height="40" HorizontalAlignment="Left" Margin="12,0,0,12" Name="tbx" VerticalAlignment="Bottom" Width="100" Text="1" />
</Grid>
</Window>

說明：
在C# WPF使用System.Collections.Generic的List實現在陣列Push新值的功能。
