当我执行我的应用程序时，我收到一个错误：

我有以下xml doc：

当我尝试通过c＃访问它时：

string csvSeparator = ",";
            Func<string, string> escapeValue = val => val;

            string xml = textBox1.Text;
            XDocument doc = XDocument.Parse(xml);

            var headers = doc.Root
                            .Elements()
                            .First()
                            .Elements()
                            .Select(el => el.Name.LocalName);

            var headerRow = string.Join(csvSeparator, headers);

            var rows = from el in doc.Root.Elements()
                       let values = from prop in el.Elements()
                                    select escapeValue(prop.Value)
                       let row = string.Join(csvSeparator, values)
                       select row;


            IEnumerable<string> csvLines = new[] { headerRow }.Concat(rows);

我收到此错误：

Data at the root level is invalid. Line 1, position 1

这条线怎么了？

当我有像这行一样的属性字符串时，我还需要在excel中自动着色

<CLAFCNO VALIDE="NON">5b1</CLAFCNO>

Answer 1

我猜textBox1.Text包含xml文件的名称，而不是xml本身

所以，将XDocument.Parse(xml);更改为XDocument.Load(xml);

如何在根级别修复数据无效
