Hi i want to create a list based on the search string using predicate expressions. I have a list of type products contains different names. List<products> list1 = new List<products>(); list1.Add(new products("sowmya")); list1.Add(new products("Jane")); list1.Add(new products("John")); list1.Add(new products("kumar")); list1.Add(new products("ramya")); listBox1.ItemsSource = list1; Now i want to filter the content based on user input.User will enter n no of strings with '+' as separator. After receiving the strings i will pass them to predicate object like this private void textBox1_KeyDown(object sender, KeyEventArgs e) { List<products> list2 = new List<products>(); Expression<Func<products, bool>> predicate = PredicateBuilder.True<products>(); if (e.Key == Key.Enter) { string Searchstring = textBox1.Text.ToString().Trim(); string[] separator = new string[] { "+" }; string[] SearchItems=Searchstring.Split(separator,StringSplitOptions.None); foreach (string str in SearchItems) { string temp = str; predicate =p => p.Name.Contains(temp.ToLower()); } list2 = list1.AsQueryable().Where(predicate).ToList(); listBox1.ItemsSource = list2; } } If i enter more than one string(sowmya+jane+john) its giving only the last string(john) result but i want a list of all matching strings Please answer this question because i'm trying this but i couldn't get the result. Please do some help thanks.
