SOAP标题Action未被理解

Question

I am trying to consume a webservice in C#. Whenever i try to call the function from the web service class I am getting a "SOAP header Action was not understood".I've added web reference[not service reference] pointing the web service in my project. The following steps were taken to add the web reference

1) right click on the project -> Add WebReference

when i examined the web service in web browser i found this in the header

<wsdl:definitions name="MyService" targetNamespace="http://tempuri.org/">
    <wsp:Policy wsu:Id="WSHttpBinding_ICAIService_policy">
        <wsp:ExactlyOne><wsp:All><sp:TransportBinding>
    <wsp:Policy>

I've done the following code to call the web service functions

WebStruct webS = new WebStruct();
webS.Name = "Peter";
webS.ID = 22;

webS.Find(webS);

Answer 1

删除Web引用并添加服务引用。

Answer 2

Try to use simple service endpoint binding BasicHttpBinding. This binding is compatible with .NET 2.0.

Answer 3

SoapAction errors only went away when I went into the "Configure Service Reference..." properties and updated the Service Reference with these options ticked.

and ticked these two boxes:

TICK Generate asynchronous operations TICK Always generate message contracts

Answer 4

Can you check with your webservice provider? Seems they need some customized header information to process your request. Adding such headers by the service providers are very much common to increase the security.

Answer 5

here is some nice code too if you need it:

//Set username and password for Basic Auth
service.ClientCredentials.UserName.UserName = "usernamehere";
service.ClientCredentials.UserName.Password = "passwordhere";

//Ignore invalid SSL certs
System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
