WebClient问题

[sunrise10]

Byte[] bytePageData;
WebClient wc = new WebClient();
wc.Credentials = CredentialCache.DefaultCredentials;

NameValueCollection na = new NameValueCollection();

bytePageData = wc.DownloadData("www.aaa.com/index.aspx?bb=bb");
如果www.aaa.com/index.aspx是接收一post方式接收bb的值,改怎么修改这段程序,完成相同的功能呢?

string uriString = "http://www.contoso.com/search";
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Create a new NameValueCollection instance to hold the QueryString parameters and values.
NameValueCollection myQueryStringCollection = new NameValueCollection();
Console.Write("Enter the word(s), separated by space character to search for in " + uriString + ": ");
// Read user input phrase to search for at uriString.
string searchPhrase = Console.ReadLine();
if (searchPhrase.Length > 1)
// Assign the user-defined search phrase.
myQueryStringCollection.Add("q",searchPhrase);
else
// If error, default to search for 'Microsoft'.
myQueryStringCollection.Add("q","Microsoft");
// Assign auxilliary parameters required for the search.
Console.WriteLine("Searching " + uriString + " .......");
// Attach QueryString to the WebClient.
myWebClient.QueryString = myQueryStringCollection;
// Download the search results Web page into 'searchresult.htm' for inspection.
myWebClient.DownloadFile (uriString, "searchresult.htm");
Console.WriteLine("\nDownload of " + uriString + " was successful. Please see 'searchresult.htm' for results.");

webclient有个方法就是下载文件的啊

[liuyu1981831]

WebClient myWebClient = new WebClient();
NameValueCollection myNameValueCollection = new NameValueCollection();
myNameValueCollection.Add("query",Value);
byte[] responseArray = myWebClient.UploadValues(URL,"POST",myNameValueCollection );

[liuyu1981831]

byte[] responseArray = myWebClient.UploadValues(URL,"POST",myNameValueCollection );
其中 URL = "www.aaa.com/index.aspx"

[liuyu1981831]

myNameValueCollection.Add("query",Value);

应改为
myNameValueCollection.Add("bb","bb的值");
