Question

当我尝试从C＃代码访问Tomcat中托管的Web服务时，我收到这样的错误消息。

There was an error in serializing body of message searchRepositoriesRequest: '
Unable to generate a temporary class (result=1).
error CS0266: Cannot implicitly convert type 'object' to 'object[]'. An explicit
 conversion exists (are you missing a cast?)
error CS0266: Cannot implicitly convert type 'object' to 'object[]'. An explicit
 conversion exists (are you missing a cast?)
error CS0266: Cannot implicitly convert type 'object' to 'object[]'. An explicit

'.  Please see InnerException for more details.

有人能帮帮我吗？请参考下面给出的堆栈跟踪。

我们遇到了同样的问题。我相信你会在wsdl的某个地方找到一个列表列表，即一个元素，其中maxOccurs = unbounded，type是单个元素的序列，maxOccurs = unbounded。

有关此案的另一个案例，请参阅'Error serializing body'. Problem calling Fedex webservice through .NET 3.5。

可能的解决方案包括修改wsdl而不使用列表列表（例如，在内部类型中添加虚拟字段），或者按照其他链接上的建议手动编辑生成的代码。

从dotnet客户端调用Java Web服务
