WPF中使用Hashtable剔除重复字符串(比如电话号码)
原文: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

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[] { ',' });
}
