如何解决错误“调用的目标已引发异常”

Question

当我运行下面的代码时，它显示错误

“调用目标抛出异常”

我能做些什么来解决这个问题？

public LinqToXml()
{
    XDocument document = XDocument.Load(@"D:\\Data.xml");
    #region Fetch All the Books
    var books = from r in document.Descendants("book") 
                select new
                {
                    Author = r.Element("author").Value,
                    Title = r.Element("title").Value,
                    Genere = r.Element("genre").Value,
                    Price = r.Element("price").Value,
                    PublishDate = r.Element("publish_date").Value,
                    Description = r.Element("description").Value,

                };

    foreach (var r in books)
    {
        com_xdocuments.Items.Add(r.PublishDate + r.Title + r.Author);                            

    }

    #endregion 
}

Answer 1

不应该

XDocument document = XDocument.Load(@"D:\Data.xml");

两者都是相同的@"D:\Data.xml" 和"D:\\Data.xml"
