.NET Forum / ASP.NET / Web Services / October 2007Please help : The request failed with HTTP status 505: HTTP Version Not Supported.
Hi, I'm quite new in WebServices. I work in VS2003, C#. My code is : MyWebReference.ClassX x1=new MyWebReference.ClassX(); x1.Url="address to wsdl"; System.Net.NetworkCredential nc=new System.Net.NetworkCredential("user","password","domain"); x1.Credentials=nc; and after execute this code : x1.SomeSendMethod(par1,par2); I get "The request failed with HTTP status 505: HTTP Version Not Supported." How can I check/change the version of HTTP? I can't find how to resolve this problem. And the second question : Can I use a System.Net.WebRequest to work with WebService and if so, how I can involve SomeSendMethod with parameters? please help! JACK You don't mention on which type of Web server the Web service is located. Is it IIS?

Is > it IIS? Yes, it is. and server accepts HTTP 1.0 and 1.1. I'm assuming this is your own Web service, so can you browse to it from a browser (in Visual Studio, right-click the .asmx file in Solution Explorer and click View in Browser? If so, can you add a reference from within Visual Studio (right-click your project in Solution Explorer and click Add Web Reference)?

But of course I've added this to my project as a Web reference. I can see all definitions in WSDL but when I want to send some request I receive HTTP 505 exception. Can I define version of HTTP in a header of a request? But how to do this, when I only execute a method like x1.SomeSendMethod(par1,par2)?
