错误处理问题

[songq]

byte[] buf = new byte[38192];
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(textBox1.Text);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
}
catch(Exception ep)
{
MessageBox.Show(ep.ToString());
return;
}

//***
Stream resStream = response.GetResponseStream();
int count = resStream.Read(buf, 0, buf.Length);
textBox2.Text = Encoding.Default.GetString(buf, 0, count);
resStream.Close();

这段代码编译的时候，总是报：找不到类型或命名空间名称“response”(是否缺少 using 指令或程序集引用？)，把//***下边的语句去掉就没事了，请问这个错误处理我该怎么写才不会出错，多谢了

HttpWebRequest request ;
HttpWebResponse response ;
byte[] buf = new byte[38192];
try
{
request = (HttpWebRequest)WebRequest.Create(textBox1.Text);
response = (HttpWebResponse)request.GetResponse();
}
catch(Exception ep)
{
MessageBox.Show(ep.ToString());
return;
}

//***
Stream resStream = response.GetResponseStream();
int count = resStream.Read(buf, 0, buf.Length);
textBox2.Text = Encoding.Default.GetString(buf, 0, count);
resStream.Close();

不好意思。。以为是在page中，楼上hbzx(^&^)正确,变量作用范围
