C# 调用ie打开URL地址

//方法一

            Process ps = new Process();
            string yourURL = "http://www.fqjyxx.com";
            ps.StartInfo.FileName = "iexplore.exe";
            ps.StartInfo.Arguments = yourURL;
            ps.Start();

 //方法二比较直接，但不好用，不知道原因
          * //System.Diagnostics.Process.Start(textBox2.Text.Trim());
            */

 

我的代码使用方法1 OK
            if (textBox2.Text.Trim().Equals(""))
            {
                MessageBox.Show("请输入视频的URL地址！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
           
            Process ps = new Process();
            string yourURL = textBox2.Text.Trim();
            ps.StartInfo.FileName = "iexplore.exe";
            ps.StartInfo.Arguments = yourURL;
            ps.Start();
