推荐答案

// Call this from whatever thread you like.
void SetTextBoxText(RichTextBox box, string text)
{
    // Accessing a GUI object from another thread than GUI is not permitted
    //   There are three exceptions to that: InvokeRequired, BeginInvoke, Invoke
    if (box.InvokeRequired)
    // Called from another thread than GUI thread.
    //   Delegate work to GUI thread and exit.
    {
        box.Invoke(new Action<string>(SetTextBoxText), new object[] { box, text });
        return;
    }
    // We're in GUI thread now. Accessing the GUI object is safe.
    box.Text = text;
}
