我有一个正在读取的 XML 文件并试图反序列化为一个对象。我尝试时收到此错误：

System.InvalidOperationException: 'XML 文档 (2, 2) 中存在错误。' InvalidOperationException：不是预期的。

这是 XML 文件：

<?xml version="1.0" encoding="utf-8" ?>
<ns6:ACABulkRequestTransmitterStatusDetailResponse xmlns="urn:us:gov:treasury:irs:ext:aca:air:ty20" xmlns:ns2="urn:us:gov:treasury:irs:common" xmlns:ns3="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:ns4="http://www.w3.org/2000/09/xmldsig#" xmlns:ns5="urn:us:gov:treasury:irs:msg:acasecurityheader" xmlns:ns6="urn:us:gov:treasury:irs:msg:irstransmitterstatusrequest">

        </ns2:BulkExchangeFile>

谁能告诉我我做错了什么？谢谢。

【问题讨论】：

尝试另一个简单的 xml，同样的错误？ XML 有“ACABulkRequestTransmitterStatusDetailResponse”，c# 代码有“ACABulkRequestTransmitterStatusDetailResponseType” @jdweng 感谢您的回复。我更新了原始帖子以包含您建议的更改，但是当我运行它时仍然遇到相同的错误。 【参考方案1】：

我认为这里有很多问题，更具体地说是 XML 的生成代码。

在 Visual Studio 中，我创建了一个新类并复制了您的 XML 内容并使用了编辑 -> 选择性粘贴 -> 将 XML 粘贴为类。

这是该练习生成的代码：

        [System.Xml.Serialization.XmlAttributeAttribute()]
        public string href
        
            get
            
                return this.hrefField;
            
            set
            
                this.hrefField = value;

使用您的 Deserialize 方法和这个新类，我能够成功解析您的 XML 文件。

我会使用这个类与您自己的生成代码进行比较，看看主要区别在哪里。除非您有范围替换生成的代码？

我能发现的第一个是 ACABulkRequestTransmitterStatusDetailResponse 部分类上方的属性需要修改为：

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.8.4084.0")]
    [System.SerializableAttribute()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "urn:us:gov:treasury:irs:msg:irstransmitterstatusrequest")]
    [System.Xml.Serialization.XmlRootAttribute(Namespace = "urn:us:gov:treasury:irs:msg:irstransmitterstatusrequest", IsNullable = false)]

希望这对您有所帮助。

谢谢凯夫。这确实有帮助。【参考方案2】：

我发现了两个问题：

更改如下：从： [System.Xml.Serialization.XmlTypeAttribute(Namespace = "urn:us:gov:treasury:irs:ext:aca:air:ty20")] 到： [XmlRoot(Namespace = "urn:us:gov:treasury:irs:msg:irstransmitterstatusrequest")]

我更新这部分代码

     private byte[] BulkExchangeFileType;

     /// <remarks/>
     /// 
     //changed to string from bytes.
     [System.Xml.Serialization.XmlElementAttribute(Namespace = "urn:us:gov:treasury:irs:common")]
     public object BulkExchangeFile
     
         get
         
             return Encoding.UTF8.GetString(this.BulkExchangeFileType);
         
         set
         
             this.BulkExchangeFileType = Encoding.UTF8.GetBytes(value.ToString());
             this.RaisePropertyChanged("BulkExchangeFile");
