C# Multi List

標題：C#多維List寫法
C# (Program.cs)：

using System;
using System.Collections.Generic;

namespace MultiList
{
    class Program
    {
        static void Main(string[] args)
        {
            //建立一維List
            List<String> titles = new List<String>() {
                "ChatBoxy",
                "CodeBoxy",
                "ToolBoxy"
            };

            //建立一維List
            List<String> websites = new List<String>() {
                "http://chatboxy.blogspot.com/",
                "http://codeboxy.blogspot.com/",
                "http://toolboxy.blogspot.com/"
            };
            
            //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：
CodeBoxy QQBoxy http://codeboxy.blogspot.com/ http://qqboxy.blogspot.com/

說明：
C#多維List新增移除資料後印出內容。

using System.Linq;

namespace WPFConfirmOptions

    public partial class Confirm : Window
    {
        public Confirm(string header, string message, List<Option> options)
        {
            InitializeComponent();
            this.Header = header;
            this.Message = message;

            {
                return CheckedName;
            }
        }

        public class Option

            int key = 0;
            foreach (Option value in Options) // Create Options
            {
                RadioButton radioButton = new RadioButton();
                radioButton.Name = value.Name;
                radioButton.Content = value.Description;
                radioButton.Height = 20;
                radioButton.Width = 250;
                radioButton.Margin = new Thickness(0, (20 + 30 * key), 0, 0);
                radioButton.HorizontalAlignment = HorizontalAlignment.Center;
                radioButton.VerticalAlignment = VerticalAlignment.Top;
                radioButton.IsChecked = false;
                this.OptionsGrid.Children.Add(radioButton);
                this.RegisterName(radioButton.Name, radioButton);
                key++;
            }
            Windows.Height = 200 + 30 * key;
            return;
        }

        private void btn_OK_Click(object sender, RoutedEventArgs e)
        {
            foreach (Option value in Options)
            {
                RadioButton radiobutton = (RadioButton)OptionsGrid.FindName(value.Name);
                if (radiobutton.IsChecked == true)
                {
                    CheckedName = radiobutton.Name;
                    DialogResult = true;
                    return;
                }
            }
            System.Windows.MessageBox.Show("No Select.");
        }

        private void btn_Cancel_Click(object sender, RoutedEventArgs e)
        {
            DialogResult = false;
            return;
        }
    }
}

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。

CSharp Goes to

標題：C#使用goes to(=>)(等於大於)語法範例
C# (Program.cs)：

using System;
using System.Linq;

namespace GoesTo
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] words = { "Welcome", "to", "CodeBoxy" };
            string shortestWord = words.OrderBy(w => w.Length).FirstOrDefault(); //Find shortest word
            int shortestWordLength = words.Min(w => w.Length); //Find the length of the shortest word
            Console.WriteLine(shortestWord + "\n" + shortestWordLength);
        }
    }
}

結果：
to 2

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)：

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。

C# WPF Using List

標題：C# WPF使用List功能
C# (MainWindow.xaml.cs)：

using System;
using System.Windows;

namespace WPFVectorList
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        public System.Collections.Generic.List<int> arr = new System.Collections.Generic.List<int>();

        private void btn_show_Click(object sender, RoutedEventArgs e)
        {
            tbk.Text = "";
            foreach (int i in arr)
            {
                tbk.Text += i + "\n";
            }
        }

        private void btn_add_Click(object sender, RoutedEventArgs e)
        {
            arr.Add(Int32.Parse(tbx.Text));
        }
    }
}

WPF (MainWindow.xaml)：

<Window x:Class="WPFVectorList.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <TextBlock Margin="12,12,12,65" Name="tbk" />
        <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。
