如何调用具有list参数的wcf服务

Question

我有一个网络服务，如下所示

   <OperationContract()>
   <Web.WebGet(UriTemplate:="/GetData?strErrMsg={strErrMsg}&chrErrFlg={chrErrFlg}", ResponseFormat:=WebMessageFormat.Json, BodyStyle:=WebMessageBodyStyle.Wrapped)> _
    Function GetData(ByRef strErrMsg As System.Collections.Generic.List(Of String), ByRef chrErrFlg As String) As String

我正在尝试将其作为

获取

http://BedTypeMasterService.svc/GetData?strErrMsg= “FF” ＆安培; chrErrFlg = “DD”

但是它给出了以下错误

合同'iBedTypeMaster'中的'GetData'操作有一个名为'strErrMsg'的查询变量，类型为'System.Collections.Generic.List 1[System.String]', but type 'System.Collections.Generic.List 1 [System.String]'不能由'QueryStringConverter'转换。 UriTemplate查询值的变量必须具有可由“QueryStringConverter”转换的类型。

请帮我解决这个问题

根据提供的链接，我尝试这样

      <behaviors>

  <endpointBehaviors>
    <behavior name="webHttpBehavior">
      <customWebHttp/>
    </behavior>


  </endpointBehaviors>

 <extensions>
  <behaviorExtensions>
    <add name="customWebHttp" type="WcfServices.BedTypeMaster.bclsBedTypeMaster, WcfServices" />
  </behaviorExtensions>
</extensions>


      <service behaviorConfiguration="ServiceBehavior" name="WcfServices.BedTypeMaster.bclsBedTypeMaster">
    <endpoint address="" binding="webHttpBinding"
              bindingConfiguration="webHttpBindingWithJsonP" contract="WcfServices.BedTypeMaster.iBedTypeMaster"
              behaviorConfiguration="webHttpBehavior">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="basicHttpBinding" contract="IMetadataExchange" />
  </service>
