根据 XSD 生成的 class 文件反序列化 XML 字符串

Question

我正在尝试根据 XSD 模式创建的 classes 反序列化一个 XML 答案，但它总是 returns null。

XML 文件具有这种格式

    <?xml version="1.0" encoding="utf-16"?>
<Responses xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      <Response>
        <inv_number>1</inv_number>
        <StatusCode>Success</StatusCode>
        <Uid>271D95D28716B37A330A5A476AE530206828B103</Uid>
        <Mark>1000000912965</Mark>
      </Response>
      <Response>
        <inv_number>2</inv_number>
        <StatusCode>ValidationError</StatusCode>
        <Errors>
          <Error>
            <Message>Author AFM is not the same with User AFM</Message>
            <Code>-1</Code>
          </Error>
        </Errors>
      </Response>
</Responses>

我的 class 文件基于 XSD 模式（用 xsd.exe 生成）是：

using System.Xml.Serialization;

// 
// This source code was auto-generated by xsd, Version=4.6.1055.0.
//

public partial class ResponseDoc {

    private ResponseType[] responseField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("response")]
    public ResponseType[] response {
        get {
            return this.responseField;
        }
        set {
            this.responseField = value;
        }
    }
}

public partial class ResponseType {

    private int entitylineNumberField;

    private string statusCodeField;

    private object[] itemsField;

    /// <remarks/>
    public int entitylineNumber {
        get {
            return this.entitylineNumberField;
        }
        set {
            this.entitylineNumberField = value;
        }
    }

    /// <remarks/>
    public string statusCode {
        get {
            return this.statusCodeField;
        }
        set {
            this.statusCodeField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("entityMark", typeof(long))]
    [System.Xml.Serialization.XmlElementAttribute("entityUid", typeof(string))]
    [System.Xml.Serialization.XmlElementAttribute("errors", typeof(ResponseTypeErrors))]
    public object[] Items {
        get {
            return this.itemsField;
        }
        set {
            this.itemsField = value;
        }
    }
}

public partial class ResponseTypeErrors {

    private ErrorType[] errorField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("error")]
    public ErrorType[] error {
        get {
            return this.errorField;
        }
        set {
            this.errorField = value;
        }
    }
}

public partial class ErrorType {

    private string messageField;

    private int codeField;

    /// <remarks/>
    public string message {
        get {
            return this.messageField;
        }
        set {
            this.messageField = value;
        }
    }

    /// <remarks/>
    public int code {
        get {
            return this.codeField;
        }
        set {
            this.codeField = value;
        }
    }
}

我反序列化 XML 答案的代码是

XmlSerializer serializer = new XmlSerializer(typeof(ResponseType),new XmlRootAttribute("Responses"));
ResponseType resultingResponse = (ResponseType)serializer.Deserialize(new StringReader(result));

如果我不把

new XmlRootAttribute("Responses")

它给了我一个例外

system.invalidOperaionException  <Responses xmlns=''> was not expected.

如果我使用它，它只会给我空的结果。我也尝试删除

[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]

按照建议但没有任何改变。
