WCF WSDL +的nillable属性 [英] WCF WSDL + Nillable Attributes

问题描述

我有一个平顶WSDL WCF服务和消费者在其另一端是告诉我的nillable =真的属性冲水它们。我试着设置在我的服务合同EmitDefaultValue =假的，但我没有发现任何行为改变。

诚然，我从来没有在这个挖成生成WSDL之前的水平，所以我有点失落。也许那里的代码下面贴，可能会解决我的问题位进行一个调整？如果我至少在正确的位置的时候，我会继续调查。

有一个简单的方法来消除从我的WSDL中的nillable =真属性，并且是将有意想不到的后果？ ！谢谢

解决方案

有没有直接简单的方式来实现这一目标。你将不得不使用 WsdlExporter 实施它自己。它是否会带来意想不到的后果取决于你的意图： - ）

编辑：

有一个看 IWSDLExportExtension 的MSDN的例子。它可以让你做的正是你想要的。诚然，这是一个有点麻烦得到它的权利，但你正在寻找在正确的方向。

I have a WCF service with a Flattened WSDL, and the consumer at the other end is telling me the nillable="true" attributes are hosing them up. I tried setting EmitDefaultValue = false in my service contract, but I didn't notice any change in behavior.

Admittedly, I have never had to dig into WSDL generation at this level before so I'm a little lost. Perhaps there a tweak to be made in the bit of code posted below that may solve my problem? If I'm at least in the correct place, I'll keep investigating.

Is there a simple way to remove the nillable="true" attributes from my WSDL, and is that going to have unintended consequences? Thanks!

public class FlatWsdl : IWsdlExportExtension, IEndpointBehavior
{
    public void ExportEndpoint(WsdlExporter exporter, WsdlEndpointConversionContext context)
    {
        XmlSchemaSet schemaSet = exporter.GeneratedXmlSchemas;

        foreach (ServiceDescription wsdl in exporter.GeneratedWsdlDocuments)
        {
            List<XmlSchema> importsList = new List<XmlSchema>();

            foreach (XmlSchema schema in wsdl.Types.Schemas)
            {
                AddImportedSchemas(schema, schemaSet, importsList);
            }

            wsdl.Types.Schemas.Clear();

            foreach (XmlSchema schema in importsList)
            {
                RemoveXsdImports(schema);
                wsdl.Types.Schemas.Add(schema);
            }
        }
    }

    ...omitted the rest of FlatWsdl.cs for brevity...
}

解决方案

There's no direct simple way to achieve this. You'll have to use WsdlExporter to implement it yourself. Whether it will have unintended consequences depends on your intentions :-)

EDIT:

Have a look at the MSDN example of IWSDLExportExtension. It will allow you to do exactly what you want. Admittedly, it's a bit of a hassle to get it right, but you're looking in the right direction.
