ASP.net 4.0 c# 中的可选参数
我有一个用 ASP.NET 4.0 构建的网站，目前有一个包含 URL 的下拉框、一个转到该 URL 并解析文本的按钮，最后是一个包含解析文本的结果框。
我想要做的是，我不想访问我的网站并在下拉框中选择 URL，而是希望将参数作为完整 URL 传递，然后让按钮转到该网站，然后执行其操作。有点像我可以交给用户的永久链接
例如：
http://localhost:62554/WebSite5 /Default.aspx --> http://google.com
google.com 被放入一个变量中（假设它的 MyURL ）并且按钮就像在下拉框中一样接受它。 处收到错误 500
using (StreamReader objReader = new StreamReader(objRequest.GetResponse().GetResponseStream()))
string newURL;
String url;
protected void Page_Load(object sender, EventArgs e)
{
//Request.Params.Get("newURL").ToString();
//string url = Request["newURL"];
//url = Request.QueryString["newURL"].ToString();
url = Request.QueryString["newURL"].ToString();
parseButton_Click(sender, e);
}
protected void parseButton_Click(object sender, EventArgs e)
{
//MyURL = deviceCombo.Text;
//MyURL = Request.Params.Get("");
//MyURL = Request.Params.Get("newURL");
//MyURL = newURL;
//string MyURL = Request.Params["newURL"].ToString();
WebRequest objRequest = HttpWebRequest.Create(url);
objRequest.Credentials = CredentialCache.DefaultCredentials;
using (StreamReader objReader = new StreamReader(objRequest.GetResponse().GetResponseStream()))
{
originalText.Text = objReader.ReadToEnd();
}
//Read all lines of file
String[] crString = { "<BR> " };
String[] aLines = originalText.Text.Split(crString, StringSplitOptions.RemoveEmptyEntries);
String noHtml = String.Empty;
for (int x = 0; x < aLines.Length; x++)
{
if (aLines[x].Contains(filterCombo.SelectedValue))
{
noHtml += (RemoveHTML(aLines[x]) + "\r\n");
}
}
//Print results to textbox
resultsBox.Text = String.Join(Environment.NewLine, noHtml);
}
**更新的代码：现在在Any ideas? ？谢谢
I have a website built in ASP.NET 4.0 and currently I have a drop down box with URLs, a button that goes to that URL and parses out text and then finally a results box with the parsed text.
What I want to do is instead of going to my website and choosing the URL in the drop down box, I want to pass on the parameter as a full URL and have the button go to that and then do its thing. Kind of like a permanent link that I can hand to a user
For instance:
http://localhost:62554/WebSite5/Default.aspx --> http://google.com
google.com gets put into a variable (lets say its MyURL) and the button takes it just like if it were in the drop down box.
**Updated code: Now getting a error 500 at
using (StreamReader objReader = new StreamReader(objRequest.GetResponse().GetResponseStream()))
string newURL;
String url;
protected void Page_Load(object sender, EventArgs e)
{
//Request.Params.Get("newURL").ToString();
//string url = Request["newURL"];
//url = Request.QueryString["newURL"].ToString();
url = Request.QueryString["newURL"].ToString();
parseButton_Click(sender, e);
}
protected void parseButton_Click(object sender, EventArgs e)
{
//MyURL = deviceCombo.Text;
//MyURL = Request.Params.Get("");
//MyURL = Request.Params.Get("newURL");
//MyURL = newURL;
//string MyURL = Request.Params["newURL"].ToString();
WebRequest objRequest = HttpWebRequest.Create(url);
objRequest.Credentials = CredentialCache.DefaultCredentials;
using (StreamReader objReader = new StreamReader(objRequest.GetResponse().GetResponseStream()))
{
originalText.Text = objReader.ReadToEnd();
}
//Read all lines of file
String[] crString = { "<BR> " };
String[] aLines = originalText.Text.Split(crString, StringSplitOptions.RemoveEmptyEntries);
String noHtml = String.Empty;
for (int x = 0; x < aLines.Length; x++)
{
if (aLines[x].Contains(filterCombo.SelectedValue))
{
noHtml += (RemoveHTML(aLines[x]) + "\r\n");
}
}
//Print results to textbox
resultsBox.Text = String.Join(Environment.NewLine, noHtml);
}
Any ideas? Thank you

你的问题很难理解，但我认为你想要做的就是在 URL 中传递网站字符串。我认为你想要做的是使用 URL 参数，所以如果他们转到“http://localhost:62554/Website5/default.aspx?newURL=http://google.com”，就好像他们选择了 google .com 在下拉列表中。
之后还有什么吗？ URL 中的内容被视为 URL 参数，您可以在代码隐藏中访问这些参数，如下所示：
Your question was hard to understand, but I think what you are trying to do is pass in the website string in the URL. I think what you want to do is use URL params, so if they go to "http://localhost:62554/Website5/default.aspx?newURL=http://google.com" it acts as if they had chosen google.com in the dropdown.
Anything after the ? in the URL is treated as an URL param, you can access these params in the codebehind like this:
您可以从 Request 对象获取 URL 变量。
将其放在您喜欢的任何地方，例如 Page_Load
You can get the URL variable from the Request object.
Put this wherever you like such as Page_Load
