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

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:

??????????? 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
??????????????? {

WPF中使用TextBlock显示长字符串的处理方法

原文:WPF中使用TextBlock显示长字符串的处理方法 在WPF中,有时候要显示长字符串,需要用到换行或者截短的情况,方法如下: 换行 可以使用<LineBreak/>标记换行: 可以用TextWrapping属性(如非特殊,推荐用这种方式,自动.自适应).它可以有NoWrap(不换行.缺省值).Wrap(换行).WrapWithOverflow(换行但允许超出文本块的宽度).WrapWithOverflow在换行的算法没办法确定如何正确换行(比如某个单词超长.换不换都超出宽度)时,允许行
