Counting the number of highlighted words in richtextbox using c#

private void button2_Click(object sender, EventArgs e)
{ 
    string[] show = richTextBox1.Text.Split(' '); 
    string type = textBox1.Text; 
    for (int i = 0; i < show.Length; i++)
    {
        int num = 0; 
        if (show[i] == textBox1.Text)
            num++;
    } 
    Label1.Text = num.ToString();   
}

Im using richTextBox1 to display the file and the textBox1 to search for a word and highlight it. I want to display how many words are highlighted in the label box but it always shows zero. Any help is appreciated.

You need to consider the new line character condition.

In my example, I remove Chr(13) and replace Chr(10) with a space, so it behaves the same way as a space character:

        string[] show = richTextBox1.Text.Replace(Convert.ToChar(13).ToString(), " ").Replace(Convert.ToChar(10).ToString(), " ").Split(' ');
        string type = textBox1.Text;
        int num = 0;
        for (int i = 0; i < show.Length; i++)
        {

            if (show[i].Trim() == textBox1.Text)
                num++;
        }
        textBox1.Text = num.ToString();

You should move int num = 0; out of your loop, since in each iteration it will be set to 0;
