推荐答案

您将从何处获取数据会很有趣.数据库，XML ...?
但是，您可以使用LINQ进行出色的搜索.

XML文件示例(可以很容易地适应您的目标，重要的是StartsWith):

Hi,

would be interesting in where you get the data from. Database, XML, ...?
However, you can do great search with LINQ.

Example with XML File (could be easily adapted for your goal, important is StartsWith):

var xElem = XElement.Load(@"c:\\adressbook.xml");
                        var name = from names in xElem.Descendants("contact")
                                   where names.Element("name").Value.StartsWith("A", StringComparison.CurrentCultureIgnoreCase)
                                   orderby names.Element("name").Value
                                   select names.Element("name").Value;
                        var matches = Enumerable.Distinct(name);

                        datacontext = matches;
                        ListBox_adressbook.ItemsSource = matches;

在TextChanged事件中，您可以使用LINQ查询来实现这一点.

In the TextChanged event you could use a LINQ query to achive this..

private void txtSearch_TextChanged(object sender, TextChangedEventArgs e)
       {
           TextBox tbox = sender as TextBox;
           string str = tbox.Text;
           var Employee = db.ResourceMasters.Where(p => (p.FirstName.Contains(str) || p.LastName.Contains(str))).Select();

       }

您可以将结果作为要显示结果的控件的itemsource..

You could put the result as itemsource for the the control you want to display the result..
