C# XML 反序列化 xmlns
本文关键字:xmlns 反序列化 XML | 更新日期: 2023-09-27 18:31:19
我的代码:
CampaignList myObject;
XmlSerializer mySerializer = new XmlSerializer(typeof(CampaignList));
**myObject = (CampaignList)mySerializer.Deserialize(xmlDoc.CreateReader());**
错误:
<CampaignListXml xmlns='api.paycento.com/1.0'> werd niet verwacht.
[InvalidOperationException: <CampaignListXml
xmlns='api.paycento.com/1.0'> werd niet verwacht.]
Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderCampaignList.Read4_CampaignListXml()
+214
该 xml 响应:
<CampaignListXml xmlns="api.paycento.com/1.0" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Allcampaign>
</Allcampaign>
</CampaignListXml>
我尝试将编码参数添加到反序列化方法,但它给出了错误"XMLSerializer不支持UTF8"。我尝试了 UTF8、UTF-8 和 System.Text.Encoding.UTF8.EncodingName;
这是整个代码,如果你想遵循它。
public IEnumerable<Campaign> GetCampaigns()
{
return GetCampaigns("active", 0, 50, "", "");
}
public IEnumerable<Campaign> GetCampaigns(string status, int startIndex, int pageSize, string orderby, string sort)
{
return GetCampaigns(status, startIndex, pageSize, orderby, sort, SessionKey);
}
public IEnumerable<Campaign> GetCampaigns(string status, int startIndex, int pageSize, string orderby, string sort, string sessionKey)
{
if (string.IsNullOrEmpty(sessionKey) || sessionKey.Length != 34)
throw new ArgumentException("Session key must be 34 chars long. " + sessionKey.Length);
string suffix = String.Format("campaigns/all/?status={0}&start={1}&psize={2}&orderby={3}&sort={4}&session={5}", status, startIndex, pageSize, orderby, sort, sessionKey);
string uri = BASE_URL + suffix;
string response = PerformAndReadHttpRequest(uri, "GET", "");
string xml = "<CampaignListXml " + response.Substring(response.IndexOf('>'));
CampaignList myObject;
XmlReaderSettings settings = new XmlReaderSettings();
using (StringReader textReader = new StringReader(xml))
{
using (XmlReader xmlReader = XmlReader.Create(textReader, settings))
{
XmlSerializer mySerializer = new XmlSerializer(typeof(CampaignList));
myObject = (CampaignList)mySerializer.Deserialize(xmlReader);
}
}
return myObject.Campaign;
}

StreamReader loResponseStream = new StreamReader(response.GetResponseStream(), enc);
string returnVal = loResponseStream.ReadToEnd();
loResponseStream.Close();
response.Close();
return returnVal;
}

}
你的 CompaignList 类应该用 XmlRootAttribute 修饰,如下所示
[XmlRoot("CampaignListXml", Namespace = "api.paycento.com/1.0")]
public class CampaignList
{
}
然后你可以从xml反序列化它,如下所示
using (StringReader reader = new StringReader(xml))
{
XmlSerializer serializer = new XmlSerializer(typeof(CampaignList));
CampaignList x1 = serializer.Deserialize(reader) as CampaignList;
}
使用这个:
XmlReaderSettings settings = new XmlReaderSettings();
using (StringReader textReader = new StringReader(xml))
{
using (XmlReader xmlReader = XmlReader.Create(textReader, settings))
{
myObject =(CampaingList)mySerializer.Deserialize(xmlReader);
}
}
这样,您可以使用中间文本读取器直接反序列化 xml 字符串。
当您不再需要流时,可以使用它们来关闭/处置它们。如果您感觉更舒服,可以显式重写它。
