Answer 1

用委托,invoke，我刚碰到过
我还有个问题呢，有时间帮我看下http://topic.csdn.net/u/20110823/15/6e02718d-fedb-475e-b142-132dcb9634e4.html?98078

例：
private delegate void WriteTxtDelegate(TextBox tb,string p_info);
 private void WriteTextBox(TextBox tb,string p_info)
        {
            if (this.InvokeRequired)
            {
                this.BeginInvoke(new WriteTxtDelegate(WriteTextBox), new object[] { tb, p_info });
            }
            else
            {
                lock (sTxtBoxObj)
                {
                    try
                    {
                        int intLine = System.Text.RegularExpressions.Regex.Matches(tb.Text, "\r\n").Count;
                        if (intLine > 200)
                            tb.Text = DateTime.Now.ToString() + "：" + p_info + "\r\n";
                        else
                            tb.Text += DateTime.Now.ToString() + "：" + p_info + "\r\n";                        tb.Select(tb.TextLength, 0);
                        tb.ScrollToCaret();
                    }
                    catch { }
                }
            }        }还有，你给的分太少了

Answer 3

private void setTextBox1Visible_Click(object sender, EventArgs e)
{
    Action func = () =>
    {
        this.textBox1.Visible = true;
    };
    if (this.textBox1.InvokeRequired)
    {
        this.textBox1.Invoke(func);
    }
    else
    {
        func();
    }
}
