WCF：有没有尽在OperationContract的参数所需的属性？ [英] WCF: is there an attribute to make parameters in the OperationContract required?

问题描述

我用 [数据成员（IsRequired = TRUE）] 进行必要的DataContract属性。似乎没有被一些IsRequired为OperationContract的参数。如何使他们所需的，而不是允许空？

在OperationContract的所述的参数似乎是在了SoapUI工具可选的。虽然这绝不是可选的或空。

WCF接口：

  [OperationContract的]
IsClientUpdateRequiredResult IsClientUpdateRequired（IsClientUpdateRequiredInput versie）;...[DataContract]
公共类IsClientUpdateRequiredInput
{
    [数据成员（IsRequired =真）]
    公共字符串CLIENTNAME {搞定;组; }
    [数据成员（IsRequired = TRUE，令= 0）]
    公众诠释重大{搞定;组; }
    [数据成员（IsRequired = TRUE，订单= 1）]
    公众诠释轻微{搞定;组; }
    [数据成员（IsRequired = TRUE，令= 2）]
    公众诠释构建{搞定;组; }
    [数据成员（IsRequired = TRUE，令= 3）]
    公众诠释修订{搞定;组; }
}
 

的soapUI请求模板：

解决方案

不幸的是，不能使用默认的WCF来完成。存在几个解决方法：

• 自定义 RequiredParametersBehavior 属性


• 使用验证应用程序块从企业库和规则集关联到你的方法

但是，您可以实现一个FaultContract并抛出一个错误，当输入参数为null。

I use [DataMember(IsRequired=true)] to make the DataContract properties required. There doesn't seem to be some IsRequired for the OperationContract parameters. How do I make them required and not allow null?

The parameter in of OperationContract appears to be optional in SoapUI tool. Though this must never be optional or null.

WCF Interface:

[OperationContract]
IsClientUpdateRequiredResult IsClientUpdateRequired(IsClientUpdateRequiredInput versie);

...

[DataContract]
public class IsClientUpdateRequiredInput
{
    [DataMember(IsRequired=true)]
    public string clientName { get; set; }
    [DataMember(IsRequired = true, Order = 0)]
    public int major { get; set; }
    [DataMember(IsRequired = true, Order = 1)]
    public int minor { get; set; }
    [DataMember(IsRequired = true, Order = 2)]
    public int build { get; set; }
    [DataMember(IsRequired = true, Order = 3)]
    public int revision { get; set; }
}

soapUI request template:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:tem="http://tempuri.org/" xmlns:pir="http://schemas.datacontract.org/2004/07/PirIS.Web.WCF.InputClasses">
   <soap:Header/>
   <soap:Body>
      <tem:IsClientUpdateRequired>
         <!--Optional:-->
         <tem:versie>
            <pir:clientName>?</pir:clientName>
            <pir:major>?</pir:major>
            <pir:minor>?</pir:minor>
            <pir:build>?</pir:build>
            <pir:revision>?</pir:revision>
         </tem:versie>
      </tem:IsClientUpdateRequired>
   </soap:Body>
</soap:Envelope>

解决方案

Unfortunately it can't be done using default WCF. There exist a few workarounds:

• A custom RequiredParametersBehavior attribute
• Using the Validation Application Block from the Enterprise Library and associate a ruleset to your method

You can however implement a FaultContract and throw a fault when the input parameter is null.
