Question

我遇到了对XML元素进行反序列化的问题，我假设它与反序列化器找不到的XML元素中的名称空间有关。

数据来自外部源，我无法将其修改为字符串，而且我使用的是C＃4.0。

任何帮助，非常感谢。

string xml = "<boolean xmlns=\"http://schemas.microsoft.com/2003/10/serialization/\">false</boolean>";

var xSerializer = new XmlSerializer(typeof(bool));
using (var sr = new StringReader(xml)) 
using (var xr = XmlReader.Create(sr))
{
    var y = xSerializer.Deserialize(xr);
}

错误：

  HResult=-2146233079
  Message=There is an error in XML document (1, 2).

如果您按照以下方式创建序列化程序，它将起作用

var xSerializer = new XmlSerializer(typeof(bool),null, null, 
                         new XmlRootAttribute("boolean"), 
                         "http://schemas.microsoft.com/2003/10/serialization/");

如果要反序列化布尔值，则不能使用xml命名空间和属性。事实上，你必须反序列化：

string xml = "<boolean>false</boolean>";

布尔反序列化错误
