【问题描述】：

XML

<?xml version="1.0" encoding="UTF-8"?>
<orgc:Organizations xmlns:orgc="urn:workday.com/connector/orgs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

        <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？）

【参考方案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"。
