Question

我有这张桌子： ID | FILE

1 | ROOT＆GT; ELEMENT TYPE =“DATABASE”CNNSTR =“Data Source =（local）; Initial Catalog = testForDLL; Integrated Security = SSPI; Persist Security Info = False;” QUERY =“SELECT * FROM TBL1 WHERE id = 1”/＆gt; ROOT＆GT;

2 | ROOT ELEMENT TYPE =“DATABASE”CNNSTR =“Data Source =（local）; Initial Catalog = testForDLL; Integrated Security = SSPI; Persist Security Info = False;” QUERY =“SELECT * FROM TBL2 WHERE id = 1”/＆gt; ROOT＆GT;

我想从第二列加载值并用它创建一个XDOCUMENT。到目前为止我有这个代码：

using (SqlConnection conn = new SqlConnection(cnnstr))
            {
                conn.Open();
                SqlCommand com = conn.CreateCommand();

                com.CommandText = "SELECT [FILE] FROM XML_Config WHERE id=" + id;
                XDocument doc2 = new XDocument();

                XmlReader dtRead = com.ExecuteXmlReader();

                if (dtRead.Read())
                    doc2.Load(dtRead); -> This line has an error
            }

问你想要什么，以便帮助我。

我想我用这段代码解决了这个问题。

using (SqlConnection conn = new SqlConnection(cnnstr))
            {
                string xmlstr;
                conn.Open();
                SqlCommand com = conn.CreateCommand();

                com.CommandText = "SELECT [FILE] FROM XML_Config WHERE id=" + id;

                SqlDataReader dtRead = com.ExecuteReader();

                while (dtRead.Read())
                    xmlstr= dtRead.GetSqlString(0).ToString();
                XDocument docBD = XDocument.Parse(xmlstr);

                return docBD;
            }

你认为这是最好的解决方案吗？

使用SQL Server中的xml数据类型创建XDocument
