Question

The error I’m having from my thread is:

Cross-thread operation not valid. Control ‘richTextBox8’ accessed from a thread other than the thread it was created on.

I have this code I use for my List of string that is causing the error.

string[] parts = richTextBox8.Text.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);

Now I’m working with using System.Threading that requires to transform the code above into a format something like this code to work but I’m unable to do it or is there some other way?

richTextBox8.Invoke((Action)(() => richTextBox8.Text += "http://elibrary.judiciary.gov.ph/" + str + "\n"));

Answer 1

string[] parts = null;
richTextBox8.Invoke((Action)(() => 
    {
        parts = richTextBox8.Text.Split(new string[] { " " },
        StringSplitOptions.RemoveEmptyEntries); //added semicolon
    }));
