如何清除WCF服务响应中不需要的字符

我有一个WCF服务，它以XML格式向客户端发送响应。当我用Soap UI测试它时，它给了我一些额外的字符。在评论中点赞并命名为https://cf.ctr.com:DealerId'那就需要删除它们。我不确定它们是从哪里来的。这是我得到的回应：

 <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
      <s:Body>
     <ProcessXMLResponse xmlns="https://cf.ctr.com">
     <ProcessXMLResult xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <StatusCode>201</StatusCode>
        <StatusDescription>XML Validation Fails</StatusDescription>
        <comments    xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
           <a:string/>
           <a:string>The element 'Collateral' in namespace   'https://cf.ctr.com' has invalid child element 'VIN' in namespace 'https://cf.ctr.com'. List of possible elements expected: 'Vehicle' in namespace 'https://cf.ctr.com'.</a:string>
           <a:string>The 'https://cf.ctr.com:DealerId' element is invalid - The value '104213' is invalid according to its datatype 'UnsignedShort' - The Pattern constraint failed.</a:string>
           <a:string>The 'https://https://cf.ctr.com:EmploymentPeriodInMonth' element is invalid - The value '0' is invalid according to its datatype 'Integer' - The MinInclusive constraint failed.</a:string>
           <a:string>The 'https://cf.ctr.com:Name' element is invalid - The value '' is invalid according to its datatype 'String' - The actual length is less than the MinLength value.</a:string>
        </comments>
        <RemoteRefNumber>104213C3C4B606-2A10-46F4-87FA-E23</RemoteRefNumber>
     </ProcessXMLResult>
  </ProcessXMLResponse>

这是我的合同：

  [DataContract(Namespace = "https://https://cf.ctr.com")]
public class PartnerRequest
{
    // -------------------------------------------------------------------   Username and Password in SOAP's Header - START

    [DataMember(Name = "username",Order=1)]
    public string username { get; set; }
    [DataMember(Name = "password",Order=2)]
    public string password { get; set; }
    // ------------------------------------------------------------------- Username and Password in SOAP's Header --- END
    // Body
    [DataMember(Name = "PartnerID", Order=3)] 
    public int PartnerID { get; set; }
    [DataMember(Name = "PartnerName",Order=4)] 
    public string PartnerName { get; set; }
    [DataMember(EmitDefaultValue = false,Name = "CFCConnect", Order = 5)] 
    public CFCConnect CFCConnect { get; set; }

}
[DataContract(Namespace = "https://cf.ctr.com")]
public class PartnerAuthentication
{
    public PartnerAuthentication()
    {
    }
    public PartnerAuthentication(PartnerAuthentication partner)
    {
        this.Authenticated = partner.Authenticated;
        this.StatusCode = partner.StatusCode;
        this.StatusDescription = partner.StatusDescription;
        this.comments = partner.comments;
        this.RemoteRefNumber = partner.RemoteRefNumber;
    }

    //[MessageBodyMember(Order = 1, Namespace = "https://cf.ctr.com")]
     public bool Authenticated { get; set; }
     [DataMember(Name = "StatusCode", Order = 1)] 
     public int StatusCode { get; set; }
     [DataMember(Name = "StatusDescription", Order = 2)] 
     public string StatusDescription { get; set; }
     [DataMember(Name = "comments", Order = 3)] 
     public List<string> comments { get; set; }
     [DataMember(Name = "RemoteRefNumber", Order = 4)]
     public string RemoteRefNumber { get; set; }
