WebService-Requests over a proxy server

[Thomas Klein]

Hello NG,

I want to realize that my C# software is able to send its
webservice-requests over the company's proxy server. In Java I've solved
this in that way:

System.setProperty("proxySet", "true");
System.setProperty("http.proxyHost", proxyHost);
System.setProperty("http.proxyPort", proxyPort);

Is there in C# an equivalent way to do the same? I would be happy if
someone could help me! Thanks in avance!

Bye
Thomas

Thomas,
here is some sample code to get you started:


WebProxy p = null;
string proxyAddressAndPort =
ConfigurationSettings.AppSettings["proxy"];
string proxyUserName =
ConfigurationSettings.AppSettings["proxyUserName"];
string proxyPassword =
ConfigurationSettings.AppSettings["proxyPassword"];
ICredentials cred;
cred = new NetworkCredential(proxyUserName, proxyPassword);
p = new WebProxy(proxyAddressAndPort, true, null, cred);
GlobalProxySelection.Select = p;

Hope that helps.
Peter

Or directly from the webservice itself
My.Fully.QualifiedNameSpace.WebService service = new
My.Fully.QualifiedNameSpace.WebService();
WebProxy p = null;
string proxyAddressAndPort = ConfigurationSettings.AppSettings["proxy"];
string proxyUserName = ConfigurationSettings.AppSettings["proxyUserName"];
string proxyPassword = ConfigurationSettings.AppSettings["proxyPassword"];
ICredentials cred = new NetworkCredential(proxyUserName, proxyPassword);
p = new WebProxy(proxyAddressAndPort, true, null, cred);
service.Proxy = p;

Thomas,
here is some sample code to get you started:


WebProxy p = null;
string proxyAddressAndPort =
ConfigurationSettings.AppSettings["proxy"];
string proxyUserName =
ConfigurationSettings.AppSettings["proxyUserName"];
string proxyPassword =
ConfigurationSettings.AppSettings["proxyPassword"];
ICredentials cred;
cred = new NetworkCredential(proxyUserName, proxyPassword);
p = new WebProxy(proxyAddressAndPort, true, null, cred);
GlobalProxySelection.Select = p;

Hope that helps.

Thank you for your response! I've tried out in this way, but the
application does not use my proxy anyway:

public class MySettings {

public WebProxy p;

public void initializeProxySettings()
{
this.p = null;
string proxyHost = ConfigurationSettings.AppSettings["proxyHost"];
string proxyPort = ConfigurationSettings.AppSettings["proxyPort"];
string proxyUserName =
ConfigurationSettings.AppSettings["proxyUserName"];
string proxyPassword =
ConfigurationSettings.AppSettings["proxyPassword"];
ICredentials cred;
cred = new NetworkCredential(proxyUserName, proxyPassword);
p = new WebProxy(proxyHost + ":" + proxyPort, true, null, cred);
GlobalProxySelection.Select = p;
}

}

In another class, I send my webservice-request by a helper class
(CmHelper) which inherits from the class MySettings:

try {
String url = this.cmHelper.GetURL(param1,param2);
} catch (Exception e) {
System.Console.Out.WriteLine("An Exception occured
while sending the request to the CityMapService!");
System.Console.Out.WriteLine(e.Message);
System.Console.Out.WriteLine(e.StackTrace);
}

Can someone tell me what I have done wrong?
Thanks in advice!
