C# 在ASMX中读取Soap头

我有两个问题 首先，对于我的几个方法，我希望在soap:Header中传递帐户信息，然后验证该信息。它没有读取soap:头中传递的信息。我花了3天时间在谷歌上看了很多例子，它们都显示了一些与我现有的类似的东西。然而，每次我尝试它时，我都没有得到任何一个节点的值

下面是显示其中一个方法的代码

            myXml.LoadXml(sb.ToString());
            return myXml;
        }



    }
}

我的第二个问题是我需要使用一个定制的wsdl，以便我可以验证传入的soap消息。直到我添加soap:Header，然后我得到以下错误消息，这才起作用

soap:ClientSystem.Web.Services.Protocols.SoapException: Incoming message failed validation: Warning: Could not find schema information for the element 'http:www.criw.net/AssessmentServices:AuthHeader'. at SchemaValidation.ValidationExtension.xrs_ValidationEventHandler(Object sender, ValidationEventArgs e) in k:\SchemaValidation\Extensions\ValidationExtension.cs:line 437 at System.Xml.Schema.XmlSchemaValidator.SendValidationEvent(XmlSchemaValidationException e, XmlSeverityType severity) at System.Xml.Schema.XmlSchemaValidator.SendValidationEvent(String code, String msg, XmlSeverityType severity) at System.Xml.Schema.XmlSchemaValidator.ThrowDeclNotFoundWarningOrError(Boolean declFound) at System.Xml.Schema.XmlSchemaValidator.ValidateElement(String localName, String namespaceUri, XmlSchemaInfo schemaInfo, String xsiType, String xsiNil, String xsiSchemaLocation, String xsiNoNamespaceSchemaLocation) at System.Xml.XsdValidatingReader.ProcessElementEvent() at System.Xml.XsdValidatingReader.ProcessReaderEvent() at System.Xml.XsdValidatingReader.Read() at SchemaValidation.ValidationExtension.ProcessMessage(SoapMessage message) in k:\SchemaValidation\Extensions\ValidationExtension.cs:line 350 at System.Web.Services.Protocols.SoapMessage.RunExtensions(SoapExtension[] extensions, Boolean throwOnException) at System.Web.Services.Protocols.SoapServerProtocol.ReadParameters() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()http://www.criw.net/Assessment_WebService/AssessmentServices.asmx

下面是我发送的soap消息的示例

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
    <AuthHeader xmlns="http:www.criw.net/AssessmentServices">
        <Master>TEST</Master>
        <Secondary>TEST</Secondary>
    </AuthHeader>
</soap:Header>
<soap:Body>
    <GetSection xmlns="http://www.criw.net/AssessmentServices">
        <AssessmentID>1</AssessmentID>
        <FinishedSection>0</FinishedSection>
        <Language>en</Language>
    </GetSection>
</soap:Body>
</soap:Envelope>

可以在这里找到web服务

我正在验证的WSDL就在这里

我非常感谢所有帮助

ASMX是一项遗留技术，不应用于新的开发。WCF或ASP.NET Web API应用于Web服务客户端和服务器的所有新开发。一个提示：微软已经退出了MSDN。谢谢，但这并不能回答问题。谁真的在乎它是不是遗产？我知道我不知道。我们公司在经典的asp中有数百万行代码，我还看了WCF，但我找到的每一篇教程都谈到了客户机。我不在乎客户。使用我们服务的公司可以用他们想要的任何语言编写代码。我所要做的就是保护我们的信息，这样任何汤姆·迪克或哈里都无法访问这些信息，如果他们没有帐户的话。
