textbox,richtextbox 自动滚动到最底端

        private void richTextBox1_TextChanged(object sender, EventArgs e)

        {

            //richTextBoxRecieve.SelectionStart = richTextBoxRecieve.Text.Length;

            //richTextBoxRecieve.SelectionLength = 0;

            //richTextBoxRecieve.Focus();

        }

垂直滚动条始终在RichTextBox的底部

你需要设置HideSelection 为 false 并且用 AppendText来插入新数据

例如richTextBox.AppendText("内容");
