c# - 布尔反序列化错误

Question

我在反序列化 XML 元素时遇到问题，我假设它与反序列化程序未找到的 XML 元素中的命名空间有关。

数据来自外部来源，我无法将其修改为字符串，并且我使用的是 C# 4.0。

任何帮助，不胜感激。

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

Answer 1

It will work if you create your serializer as below

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

Answer 2

You can't use xml namespaces and attributes if you want to deserialize a boolean. Infact you have to deserialize this:

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