Regex -删除正则表达式
本文关键字:正则表达式 删除 Regex | 更新日期: 2023-09-27 18:05:55
我使用正则表达式来获得特定格式的字符串。经过多次操作,我想要回原来的字符串。
现在我只使用了一个模式,我正在考虑使用更多的模式,我想确定哪个模式应用于格式化字符串并将其还原为原始字符串。
这是我的代码,
string formattedId=string.empty;
/// <summary>
/// Initializes a new instance of the <see cref="MainWindow"/> class.
/// </summary>
public MainWindow()
{
this.InitializeComponent();
this.idPattern = @"^('d{3})('d{3})('d{3})";
this.idReplacement = "$1-$2+$3";
}
/// <summary>
/// Handles the OnLostFocus event of the UIElement control.
/// </summary>
/// <param name="sender">The source of the event.</param>
/// <param name="e">The <see cref="System.Windows.RoutedEventArgs"/> instance containing the event data.</param>
private void UIElement_OnLostFocus(object sender, RoutedEventArgs e)
{
string formatted = Regex.Replace(textBox.Text, this.idPattern , this.idReplacement );
formattedId = formatted;
}
public string GetOriginalString()
{
//// Now here i want to convert formatted string back to original string.
}
例如123456789字符串将被格式化为123-456+789在此之后,我想检查应用了哪个模式并将字符串恢复为原始格式
创建一个全局字符串,并将文本框的值放在该字符串中。要查看原始字符串,只需使用全局字符串:
string formattedId=string.Empty;
string OriginalStr=string.Empty;
public MainWindow()
{
this.InitializeComponent();
this.idPattern = @"^('d{3})('d{3})('d{3})";
this.idReplacement = "$1-$2+$3";
}
private void UIElement_OnLostFocus(object sender, RoutedEventArgs e)
{
OriginalStr=Convert.ToString(textBox.Text);
string formatted = Regex.Replace(textBox.Text, this.idPattern , this.idReplacement );
formattedId = formatted;
}
希望对大家有所帮助
