加载 XML 文件时出错 {“根级别的数据无效。第 1 行，位置 1。”}

Question

我已经搜索了一些关于这个错误的主题，但似乎没有一个能给我一个解决方案。

我试图使用 xml 源数据来创建我的类的实例，使用 code first mvc c#。

我的模型如下所示：

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; }
    [Display(Name = "Unscheduled Out Round")]
    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; }
    [Display(Name = "Out Punch Early Change Point")]
    public virtual string OutPunchEarlyChangePoint { get; set; }
    [Display(Name = "Out Punch Early Inside Grace")]
    public virtual string OutPunchEarlyInsideGrace { get; set; }
    [Display(Name = "Out Punch Late Outside Round")]
    public virtual string OutPunchLateOutsideRound { get; set; }
    [Display(Name = "Out Punch Late Inside Round")]
    public virtual string OutPunchLateInsideRound { get; set; }
    [Display(Name = "In Punch Late Change Point")]
    public virtual string InPunchLateChangePoint { get; set; }
    [Display(Name = "Transfer Round")]
    public virtual string TransferRound { get; set; }
    [Display(Name = "Unscheduled Out Grace")]
    public virtual string UnscheduledOutGrace { get; set; }
    [Display(Name = "Transfer Grace")]
    public virtual string TransferGrace { get; set; }
    [Display(Name = "Is Missed Out Exception")]
    public virtual bool IsMissedOutException { get; set; }
    [Display(Name = "Out Punch Late Inside Grace")]
    public virtual string OutPunchLateInsideGrace { get; set; }
    [Display(Name = "In Punch Late Outside Round")]
    public virtual string InPunchLateOutsideRound { get; set; }
    [Display(Name = "In Punch Late Outside Grace")]
    public virtual string InPunchLateOutsideGrace { get; set; }
    [Display(Name = "In Punch Early Change Point")]
    public virtual string InPunchEarlyChangePoint { get; set; }
    [Display(Name = "Unscheduled In Round")]
    public virtual string UnscheduledInRound { get; set; }
    [Display(Name = "In Punch Early Inside Grace")]
    public virtual string InPunchEarlyInsideGrace { get; set; }
    [Display(Name = "Out Punch Late Outside Grace")]
    public virtual string OutPunchLateOutsideGrace { get; set; }
    [Display(Name = "In Punch Late Inside Round")]
    public virtual string InPunchLateInsideRound { get; set; }
    [Display(Name = "In Punch Late Inside Grace")]
    public virtual string InPunchLateInsideGrace { get; set; }
    [Display(Name = "Use Scheduled Out")]
    public virtual bool UseScheduledOut { get; set; }
    [Display(Name = "Out Punch Early Outside Round")]
    public virtual string OutPunchEarlyOutsideRound { get; set; }
    [Display(Name = "Out Punch Early Outside Grace")]
    public virtual string OutPunchEarlyOutsideGrace { get; set; }
    [Display(Name = "Out Punch Early Inside Round")]
    public virtual string OutPunchEarlyInsideRound { get; set; }
    [Display(Name = "Unscheduled In Grace")]
    public virtual string UnscheduledInGrace { get; set; }
    [Display(Name = "Out Punch Late Change Point")]
    public virtual string OutPunchLateChangePoint { get; set; }
    public virtual int WorkRuleId { get; set; }
    public virtual WorkRule WorkRule { get; set; }

    [ScaffoldColumn(false)]
    public virtual DateTime DateSubmitted { get; set; }

    IEnumerable<PunchRoundRule> punchRoundRule = GetPunchRoundRule<PunchRoundRule>("http://localhost:12276/Files/WSAPunchRoundRule.xml");

    static IEnumerable<T> GetPunchRoundRule<T>(String xml)
    where T : IPunchRoundRule, new()
    {
        return XElement.Parse(xml)
            .Elements("Response")
            .Select(f => new T
            {
                PunchRoundRuleId=10,
                Name = f.Element("name").Value,

            });
    }

    public PunchRoundRule()
    {
        this.DateSubmitted = DateTime.Now;
    }

}
public interface IPunchRoundRule
{
    int PunchRoundRuleId { get; set; }
    string Name { get; set; }
}


}

我的 Xml 文件如下所示：

特定错误意味着您的 XML 文档格式不正确。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，但我建议尝试使用另一个 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您的路径错误并且流返回null。或者您可能无权访问特定文件，因此将null 排除在流之外。尝试读取文件而不解析它只是为了检查它。

希望我能帮上忙！
