You can search for a space in richTextBox1.Text, and then you can save to another string rest of the input string

so from your point of view what should i pass in my method

I think you can pass a text of the richbox, then find space that you need, and create a new string with a text that you need and you will get something like listbox1.SelectedIndex = listbox1.FindString(newFindString);
Or you can wait for alt+space event is raised, and when it raised you can save what you need in some property

Solution 1

You can use Split() method.

Have a look at the following link[^].

An example from the link;

C#

string s = "there is a cat";
//
// Split string on spaces.
// ... This will separate all the words.
//
string[] words = s.Split(' ');
foreach (string word in words)
{
    Console.WriteLine(word);
}

so in this case second word which is "is"=> you can find it in words[1]

Adaptation to your code:

SelectExactMatch(words[1]);

Good luck,
OI

Have you tried what I have suggested? Debug it and you will understand.

This code is collecting all the string .. but i need to check space before that word for which user pressed alt+space.

ex:

This Is My Ho(only before Ho i want to check space and give some suggestion related to Ho)..Thank You

So instead of words[1] you just give words[words.count-1]. which is Ho.
