svcutil不为minOccurs = 0生成指定的字段 [英] svcutil NOT generating specified fields for minOccurs=0

问题描述

使用svcutil.exe从本地文件系统上的文件的wsdl + xsd生成代码.以前使用的wsdl.exe.当字段为可选字段时(即has  minOccurs ="0")，wsdl.exe用于生成< fieldname>指定的布尔值(如果类型为 是一个值类型(例如int或enum).

Using svcutil.exe to generate code from wsdl's + xsd's on files from the local file system. Previously used wsdl.exe. When a field is optional (i.e. has  minOccurs="0"), wsdl.exe used to generate a <fieldname>Specified boolean if the type is a value type (like int or enum). 

根据文档，当用XmlSerializer调用svcutil时也应该这样做，但是在我的情况下不是.这样称呼:

According to documentation, svcutil should do this too when invoked with the XmlSerializer, but in my case it does not. Calling it like this:

svcutil WebServiceA.wsdl *.xsd /noConfig /serializer:XmlSerializer

为什么未生成指定"字段?我不想在wsdl中的字段中添加nillable，因为这意味着有所不同，并且需要在Java后端中进行更改.

Why are the Specified fields not generated? I do not want to add nillable to the fields in the wsdl, because that means something different and would require changes in the Java backend.

要复制的示例代码:

WebServiceA.wsdl:

WebServiceA.wsdl:

</definitions>

WebServiceA.xsd:

生成这样的代码.注意，getDataRequest类不包含任何可选的(Specified)字段，因此不可能执行"getData"操作.没有dataType的呼叫.这是svcutil.exe中的另一个错误吗?

Generates code like this. Note that the getDataRequest class does not contains any optional (Specified) fields, so it's impossible to do the "getData" call without a dataType. Is this another bug in svcutil.exe?

    }
    
    public getDataRequest(string id, DataType dataType)
    {
        this.id = id;
        this.dataType = dataType;
    }
}

推荐答案

有人吗?这是相当大的突破.连同我发布的其他问题，似乎svcutil是越野车的一种使用方式.我们正在考虑取消整个切换到WCF，并保持wsdl.exe:-(

Anybody? This is quite the dealbreaker. Along with the other issues I posted, it seems like svcutil is way to buggy to be used. We are thinking about cancelling the whole switchover to WCF and remain keeping wsdl.exe :-(
