.NET SOAP 1.2 - 信封版本

问：

如何将 s：Envelope 更改为 soap12：Envelope 格式？

请求标头： 内容类型：application/soap+xml;字符集=utf-8 内容长度：1251

我收到服务器错误。

我尝试使用 Postman，当我发送时它在那里工作：<soap12:Envelope xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">

但是，我正在使用此 .NET 代码，它返回：<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">

.NET 代码：System.ServiceModel.Channels.CustomBinding result = new System.ServiceModel.Channels.CustomBinding(); System.ServiceModel.Channels.TextMessageEncodingBindingElement textBindingElement = new System.ServiceModel.Channels.TextMessageEncodingBindingElement(); textBindingElement.MessageVersion = System.ServiceModel.Channels.MessageVersion.CreateVersion(System.ServiceModel.EnvelopeVersion.Soap12, System.ServiceModel.Channels.AddressingVersion.WSAddressing10); result.Elements.Add(textBindingElement); System.ServiceModel.Channels.HttpsTransportBindingElement httpsBindingElement = new System.ServiceModel.Channels.HttpsTransportBindingElement(); httpsBindingElement.AllowCookies = true; httpsBindingElement.MaxBufferSize = int.MaxValue; httpsBindingElement.MaxReceivedMessageSize = int.MaxValue; result.Elements.Add(httpsBindingElement); return result;
