XML

        <orgc:Superior_Organization>DL2Code11</orgc:Superior_Organization>
    </orgc:Organization>
</orgc:Organizations>

类

[XmlRoot(ElementName = "Organizations", Namespace = "urn: workday.com/connector/orgs", IsNullable = true )]
    public class CostCenterHierarchy
    {
        [XmlElement("orgc:Organization_ID")]
        public string CostCenterHierarchyId { get; set; }

        [XmlElement("orgc:Organization_Code")]
        public string Code { get; set; }

        [XmlElement("orgc:Organization_Name")]
        public string Name { get; set; }

        [XmlElement("orgc:Organization_Description")]
        public string Description { get; set; }

        [XmlElement("orgc:Organization_Subtype")]
        public string Subtype { get; set; }

        [XmlElement("orgc:Superior_Organization")]
        public string ParentHierarchyId { get; set; }
    }

将xml反序列化为c#类的方法

private List<CostCenterHierarchy> ProcessCostCenterHierarchy(string filePath)
        {
            var costCenterHierarchyList = new List<CostCenterHierarchy>();
            //var costCenterHierarchy = new CostCenterHierarchy();

            XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<CostCenterHierarchy>));
            using (var reader = XmlReader.Create(filePath))
            {
                var test = xmlSerializer.Deserialize(reader);
            }

            return costCenterHierarchyList;
        }

错误信息

Message = "There is an error in XML document (2, 2)."
InnerException = {"<Organizations xmlns='urn:workday.com/connector/orgs'> was not expected."}

我不确定我哪里出错了。似乎它应该很容易，但我已经玩过这个并不断收到相同的错误消息。任何帮助将非常感激。

【问题讨论】：

您的Namespace 属性包含一个不在文档中的空格（在urn: 之后）。也许这就是问题所在？（您是否尝试seralizing List<CostCenterHierarchy> 以查看结果如何？）

【解决方案1】：

下面的代码有效。您有一个数组，并且序列化不喜欢列表作为类型。 serializaer 不喜欢的 Url "urn:workday.com/connector/orgs" 必须将 "urn:" 替换为 "http://workday.com/connector/orgs"。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;



namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(FILENAME);
            XmlSerializer serializer = new XmlSerializer(typeof(Organizations));
            Organizations organizations = (Organizations)serializer.Deserialize(reader);

        }
    }
    [XmlRoot(ElementName = "Organizations", Namespace = "http://workday.com/connector/orgs")]
    public class Organizations
    {
        [XmlElement(ElementName = "Organization", Namespace = "http://workday.com/connector/orgs")]
        public List<CostCenterHierarchy> organizations { get; set; }
    }
    public class CostCenterHierarchy
    {
        [XmlElement("Organization_ID")]
        public string CostCenterHierarchyId { get; set; }

        [XmlElement("Organization_Code")]
        public string Code { get; set; }

        [XmlElement("Organization_Name")]
        public string Name { get; set; }

        [XmlElement("Organization_Description")]
        public string Description { get; set; }

        [XmlElement("Organization_Subtype")]
        public string Subtype { get; set; }

        [XmlElement("Superior_Organization")]
        public string ParentHierarchyId { get; set; }
    }

}
