XDocument.Parse在XML內引發CData異常

Question

我正在嘗試將帶有CData的xml字符串放入元素內。 但是解析部分XDocument.Parse失敗，並顯示“發生解析CDATA時文件意外結束”。 我顯然可以清理xml字符串並刪除CData，但是為什么不進行解析？

//this throws an exception
var xDoc = XDocument.Parse(GetSampleXmlText());

private string GetSampleXmlText()
    {
        //WARNING: Tests will break if element order/hierarchy is changed

        var xml =
            @"<?xml version=""1.0"" encoding=""UTF-8""?>                                                 " +

        return xml.Trim();

Answer 1

CDATA缺少結束符> 。 這是正確的語法：

<![CDATA[topsecret]]>
