Need to search substring or any matching string using auto complete entered in the textbox using C#

Question

I am trying to make a search tool but my textbox auto complete cannot search for substring,it only shows result for auto complete if the match is equivalent.

I have tried the autocomplete textbox and auto complete combo box,I need a search where if user puts in ab all string containing the substring ab should pop up.

already tried auto complete mode both text box and combo box.

textBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
AutoCompleteStringCollection col = new AutoCompleteStringCollection();
col.Add("Foo");
col.Add("Bar");
textBox1.AutoCompleteCustomSource = col;

This works only when I search "F" or "B" but not with the substring "oo" or "ar".

WinForms autocomplete can only search from the begining. You need to implement your own autocomplete. — vasily.sib, May 28 '19 at 02:55
