在使用 [KnownType] 解决类传输问题后：通过 WCF 提供类对象的数组或列表
当尝试使用 svcutil 生成协议时，我得到了这个：
Attempting to download metadata from 'http://localhost:8080/NEN_Server' using WS-Metadata Exchange or DIS
CO.
Microsoft (R) Service Model Metadata Tool

Error: Cannot obtain Metadata from http://localhost:8080/NEN_Server
If this is a Windows (R) Communication Foundation service to which you have access, please check that you
have enabled metadata publishing at the specified address. For help enabling metadata publishing, pleas

WS-Metadata Exchange Error
URI: http://localhost:8080/NEN_Server
Metadata contains insoluble link: "http://localhost:8080/NEN_Server".
Content Type application / soap + xml; charset = utf-8 is not supported by http://localhost:8080/N
EN_Server. This can be caused by mismatch of client and service bindings.
The remote server returned an error: (415) Cannot process the message because the content type 'applica
tion / soap + xml; charset = utf-8 'was not the expected type' text / xml; charset = utf-8 '..
HTTP GET Error
URI: http://localhost:8080/NEN_Server
There was an error loading "http://localhost:8080/NEN_Server".
The request failed with the error message:

<P Class="intro"> The server was unable to process the request due to an internal error. For more informa

ect the server trace logs. </ P> </ DIV> </ BODY> </ HTML>
所以我想我必须将应用程序类型设置为
application / soap + xml; charset = utf-8
但我不明白怎么做。
这是我创建当前 WCF 主机的方式：
private void createHost() {
/// Create the ServiceHost.
using (ServiceHost host = new ServiceHost(typeof(NEN), baseAddress)) {
/// Enable metadata publishing.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
host.Description.Behaviors.Add(smb);
