downloadstring

问题 I want to import text data from Google Finance, and I use this http address as a parameter to DownloadString http://www.google.com/finance/getprices?i=1200&p=1d&f=d,o,h,l,c,v&df=cpct&q=AAPL . However, the resulting string misses any newline characters, so it is really difficult to parse. Any ideas? 回答1: The line ends returned from the stream are \n opposed to the default Windows line ends \r\n (which is represented in Environment.NewLine on Windows). Try to split on all of the possible

问题 I am trying to find the index of Mauricio in a string that is downloaded from a website using webclient and download string. However, on the website it contains a foreign character, Maurício. So I found elsewhere some code string ToASCII(string s) { return String.Join("", s.Normalize(NormalizationForm.FormD) .Where(c => char.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark)); } that converts foreign characters. I have tested the code and it works. So the problem I have is that when I

问题 The following code: WebClient wc = new WebClient(); wc.Encoding = Encoding.UTF8; string Url = "http://www.tsetmc.com/tsev2/data/instinfodata.aspx?i=59266699437480384&c=64"; return wc.DownloadString(Url); code returns: �Q�T�MP�J�A|�^D����~���C�"�����l� ��;I&3=j=�iG�H9Ȓ�J�^� �j��T�Q=HH�'Qm�������1�hF�4�*�������{�x�\o? when I visit that URL in any web browser, I get: 12:29:45,A ,3540,3567,3600,3621,3690,3515,140,238204,849582597,1,20140914,122945;;1@2825@3523@3583@1700@1,1@2000@3522@3600@8700@2

问题 I am using this code to retrieve an url content: private ArrayList request(string query) { ArrayList parsed_output = new ArrayList(); string url = string.Format( "http://url.com/?query={0}", Uri.EscapeDataString(query)); Uri uri = new Uri(url); using (WebClient client = new WebClient()) { client.DownloadStringAsync(uri); } // how to wait for DownloadStringAsync to finish and return ArrayList } I want to use DownloadStringAsync because DownloadString hangs the app GUI, but I want to be able to

问题 I'm trying to perform an http GET from a web address that requires square brackets in the url request - something like : string requestconstructor = "http://address:port/datalink?test.a[somestuff]" System.Net.WebClient webClient = new System.Net.WebClient(); string result = webClient.DownloadString(requestconstructor); I've tried setting webclient encoding to utf8 and ascii, and I've tried replacing the square brackets in the string declaration with \u00b5 and \u00b6 respectively to directly

问题 Can someone point me to a tutorial or provide some sample code to call the System.Net.WebClient().DownloadString(url) method without freezing the UI while waiting for the result? I assume this would need to be done with a thread? Is there a simple implementation I can use without too much overhead code? Thanks! Implemented DownloadStringAsync, but UI is still freezing. Any ideas? public void remoteFetch() { WebClient client = new WebClient(); // Specify that the DownloadStringCallback2 method
