我正在尝试使用c＃和wcf构建ONVIF服务器。大多数都与我的服务（ONVIF设备管理器和ispy）连接得很好，但不是exacqVision。导致错误：
A first chance exception of type 'System.Xml.XmlException' occurred in
System.Runtime.Serialization.dll
Additional information: The prefix 'xmlns' can only be bound to the namespace
'http://www.w3.org/2000/xmlns/'.
我猜它是因为xmlns：xmlns =＆＃34; http：//tempuri.org/xmlns.xsd"在它的肥皂信封里。
有没有办法使用c＃/ wcf在服务器端解决这个问题？ ONVIF相机与exacqVision连接得很好，因此对他们来说不是问题。
看起来exacqVision正在使用gSOAP / 2.8。这是推荐的，但我更喜欢在C＃中执行此操作。
我在没有运气的情况下搜索了ONVIF网站。我不想花钱成为ONVIF成员，因为这似乎是一个肥皂问题而不是ONVIF。
这是使用SvcUtil生成的绑定：
<binding name="DeviceBinding">
<textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16"
messageVersion="Soap12" writeEncoding="utf-8">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
</textMessageEncoding>
<httpTransport manualAddressing="false" maxBufferPoolSize="524288"
maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous"
realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
useDefaultWebProxy="true" />
</binding>
And here's exacqVision's soap call:
