我已经搜索了一些关于此错误的主题，但似乎没有人给我一个解决方案。
我尝试使用xml源数据首先使用代码mvc c＃创建我的类的实例。
我的模型看起来像这样：
namespace PSA.Models
{
public class PunchRoundRule:IPunchRoundRule
{
public virtual int PunchRoundRuleId { get; set; }
public virtual string Name { get; set; }
[Display(Name="In Punch Early Inside Round")]
public virtual string InPunchEarlyInsideRound { get; set; }

public virtual string UnscheduledOutRound { get; set; }
[Display(Name = "In Punch Early Outside Grace")]
public virtual string InPunchEarlyOutsideGrace { get; set; }
[Display(Name = "In Punch Early Outside Round")]
public virtual string InPunchEarlyOutsideRound { get; set; }

.Elements("Response")
.Select(f => new T

}

答案 0 :(得分：0)
特定错误意味着您有一个格式不正确的XML文档。您确定提供的XML是您在代码中实际引用的XML吗？虽然对我来说似乎没问题，但我建议尝试使用其他XML编辑器或Web浏览器打开它以确认它没问题。
获得此异常的另一个原因可能是路径错误且流返回null。或者您无权访问特定文件，因此从流中获取null。尝试阅读文件而不解析它只是为了检查它。
希望我帮忙！
