c# - 期望来自命名空间 'CustomerLeads' 的元素 'http://www.w3.org/2001/XMLSchema-instance'

Question

我在运行我的应用程序时遇到以下错误:附加信息:第 2 行第 64 行错误。期望来自命名空间“http://www.w3.org/2001/XMLSchema-instance”的元素“CustomerLeads” '.. 遇到名称为“CustomerLeads”、命名空间为“”的“元素”。

我不明白为什么会收到此错误消息，因为正如您从 XML 中看到的那样，“CustomerLeads”包含在 XML 中。如果我取出命名空间，文件将不会读取元素。包括命名空间似乎可行，但似乎无法弄清楚为什么我会收到此错误。以及如何在不出现此错误的情况下添加命名空间？

<?xml version="1.0" encoding="UTF-8"?>
<CustomerLeads xsi:noNamespaceSchemaLocation="BasicCustomerLead.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <CustomerLead>
    <FirstName>Paul</FirstName>
    <LastName>Smith</LastName>
    <Email>psmith@example.com</Email>
  </CustomerLead>-<CustomerLead>
    <FirstName>Nicole</FirstName>
    <LastName>Farhi</LastName>
    <Email>nicole.farhi@example.com</Email>
  </CustomerLead>-<CustomerLead>
    <FirstName>Raf</FirstName>
    <LastName>Simons</LastName>
    <Email>rafs@example.org</Email>
  </CustomerLead>
</CustomerLeads>

代码:

namespace Customer
{
    [DataContract(Name = "CustomerLeads", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
    public class CustomerLeads
    {

        [DataMember()]
        public string FirstName { get; set; }

        [DataMember()]
        public string LastName { get; set; }

        [DataMember()]
        public string EmailAddress { get; set; }


        public CustomerLeads unSortedLeads(string xmFilelPath)
        {

            // doc.Load("C:/Users/Admin/Downloads/potentialcustomers.xml");


            ICollection<CustomerLeads> deserializedPerson;
            CustomerLeads lead;

            FileStream fs = new FileStream(xmFilelPath, FileMode.Open);
            XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(fs, new XmlDictionaryReaderQuotas());
            DataContractSerializer ser = new DataContractSerializer(typeof(CustomerLeads));


            lead = (CustomerLeads)ser.ReadObject(reader, true);
            reader.Close();
            fs.Close();

            FirstName = lead.FirstName.ToString();

            // foreach(CustomerLeads leads in deserializedPerson.)

            return lead;
        }
    }
}

你可以试试 <xsi:CustomerLeads> xsi 是 xml 命名空间。似乎错误是说它不知道 CustomerLeads 属于哪个命名空间。

<xsi:CustomerLeads xsi:noNamespaceSchemaLocation="BasicCustomerLead.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <CustomerLead>
    <FirstName>Paul</FirstName>
    <LastName>Smith</LastName>
    <Email>psmith@example.com</Email>
  </CustomerLead>-<CustomerLead>
    <FirstName>Nicole</FirstName>
    <LastName>Farhi</LastName>
    <Email>nicole.farhi@example.com</Email>
  </CustomerLead>-<CustomerLead>
    <FirstName>Raf</FirstName>
    <LastName>Simons</LastName>
    <Email>rafs@example.org</Email>
  </CustomerLead>
</xsi:CustomerLeads>

其他元素也可能需要前缀。
