WPF中使用Hashtable剔除重复字符串(比如电话号码)

本文中的输入框中的字符串是逗号隔开的,你可以换成其他特别的字符串.

本篇中的亮点:
1. 里面有一个玻璃样式按钮,用XAML制作
2. WPF下TextBox允许多行文本的设置
3. 使用Hashtable剔除重复字符串(比如电话号码)

运行时的样子:(为了保护隐私,做了虚化及其他处理)


WPF下TextBox允许多行文本的设置:
需要:
(1)将TextWrapping设为"Wrap"
(2)将AcceptsReturn设为"True"
(3)将VerticalScrollBarVisibility设置为"Visible"?

<TextBox Margin="11,121,11,15" Name="txtBoxTel" Tag="输入列表，用逗号隔开" TextWrapping="Wrap" AcceptsReturn="True" VerticalScrollBarVisibility="Visible"></TextBox>

具体参见这里:http://msdn2.microsoft.com/en-us/library/ms742157.aspx

下面XAML代码和C#代码使用Hashtable实现剔除以逗号隔开的字符串:

关键的C#代码:
?void GetTelNo(object sender, RoutedEventArgs e)
??????? {
??????????? string tels = txtBoxTel.Text;
??????????? string[] telArr = tels.Split(new char[] { ‘,‘});

??????????? txtBoxTelCount.Text = telArr.Length.ToString();

??????????? Hashtable ht = new Hashtable();
??????????? Hashtable htRepeat = new Hashtable();
??????????? for (int i = 0; i < telArr.Length; i++)
??????????? {
??????????????? try
??????????????? {
??????????????????? ht.Add(telArr[i], telArr[i]);
??????????????? }
??????????????? catch
??????????????? {
??????????????????? htRepeat.Add(i.ToString(), telArr[i]);
??????????????? }
??????????? }

??????????? StringBuilder sb = new StringBuilder();
??????????? ICollection valueColl = ht.Values;
??????????? foreach (string s in valueColl)
??????????? {
??????????????? sb.Append(s + ",");
??????????? }

??????????? StringBuilder sbRepeat = new StringBuilder();
??????????? ICollection valueCollRepeat = htRepeat.Values;
??????????? foreach (string s in valueCollRepeat)
??????????? {
??????????????? sbRepeat.Append(s + ",");
??????????? }

??????????? txtBoxTel.Text = sb.ToString().TrimEnd(new char[]{‘,‘});
??????????? txtBoxRepeatTel.Text = sbRepeat.ToString().TrimEnd(new char[] { ‘,‘ });

??????? }
