将XML转换为JSon

Question

下面是将XML转换为JSon的功能，问题是如果xml属性值为“001”，则返回为“1”。但在textview中的提琴手我得到正确的价值，JSon它不是。

有什么问题？

public string StringXmltoJSon(string xmlDoc) 
{ 
    XmlDocument I_xDoc = new XmlDocument(); 
    //string strInputXml = GetDataFromStream(xmlDoc); 
    I_xDoc.LoadXml(xmlDoc);

    sbJSON.Append("{ "); 
    XmlToJSONnode(sbJSON, I_xDoc.DocumentElement, true); 
    sbJSON.Append("}"); 
    return MSOutJson(sbJSON.ToString()); 
} 

private static Stream MSOutJson(string strjson) 
{ 
    WebOperationContext.Current.OutgoingResponse.ContentType = "application/json; charset=utf-8"; 
    return new MemoryStream(System.Text.Encoding.UTF8.GetBytes(strjson)); 
} 

// XmlToJSONnode: Output an XmlElement, possibly as part of a higher array 
private static void XmlToJSONnode(StringBuilder sbJSON, XmlElement node, bool showNodeName)

    sbJSON.Append("{"); 
    /* Build a sorted list of key-value pairs 
     where key is case-sensitive nodeName 
     value is an ArrayList of string or XmlElement

    SortedList childNodeNames = new SortedList(); 

    // Add in all node attributes

首先安装NuGet包PM> Install-Package Newtonsoft.Json
请确保您还你的文件的顶部

更新您的StringXmltoJSon看起来像这样

public string StringXmltoJSon(string xmlDoc) 
{ 
    XmlDocument I_xDoc = new XmlDocument(); 
    I_xDoc.LoadXml(xmlDoc); 
    string jsonText = JsonConvert.SerializeXmlNode(I_xDoc); 
    return jsonText; 
}
