WCF未识别的消息版本。

Question

我正在处理一个问题，我的控制台应用程序尝试通过WCF服务发送数据。我已经成功地通过另一个使用相同配置的WCF服务在我的其他控制台应用程序中发送了另一种类型的数据。

对于我在两个控制台应用程序中使用的配置：

var binding = new BasicHttpBinding();
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.Basic;
binding.MaxReceivedMessageSize = 2147483647;
var endpoint =new System.ServiceModel.EndpointAddress("the end point");

var theClient = new MyClient(binding,endpoint);
theClient .ClientCredentials.UserName.UserName = "Username";
theClient .ClientCredentials.UserName.Password = "Password";

在完成这种配置后，我使用了发送数据的方法。我还尝试通过Postman Chrome扩展程序发送从Fiddler获取的xml数据。我能够通过Postman发送xml，但不能在控制台应用程序中发送。我认为我的配置存在问题。堆栈跟踪：

有什么建议吗？

首先，当您使用wsdl文件时，需要检查您的终结点地址。您可以参考this answer。

如果您想指定特定的Soap版本，则必须将绑定修改为自定义绑定，如下所示：

var binding = new CustomBinding();

//custom text message and encoding binding configs
TextMessageEncodingBindingElement textBindingElement = new TextMessageEncodingBindingElement
{
    //specify your custom Soap message version below, in this case (Soap 1.1)
    MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap11, 
    AddressingVersion.WSAddressing10), 
    WriteEncoding = Encoding.UTF8,
    ReaderQuotas = System.Xml.XmlDictionaryReaderQuotas.Max,

};

//custom transport binding including authentication configs
HttpTransportBindingElement httpBindingElement = new HttpTransportBindingElement
{
    AllowCookies = false,
    MaxBufferSize = int.MaxValue,
    MaxReceivedMessageSize = int.MaxValue,
    TransferMode = TransferMode.Buffered,
    UseDefaultWebProxy = false,
    ProxyAuthenticationScheme = AuthenticationSchemes.Basic,
    AuthenticationScheme = AuthenticationSchemes.Basic,

};

binding.Elements.Add(textBindingElement);
binding.Elements.Add(httpBindingElement);

var endpoint = new EndpointAddress("the end point");
var client = new MyClient(binding,endpoint);
client.ClientCredentials.UserName.UserName = "Username";
client.ClientCredentials.UserName.Password = "Password";
