從SQL Server創建具有xml數據類型的XDocument

Question

我有此表：ID | FILE

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

2 | ROOT ELEMENT TYPE =“ DATABASE” CNNSTR =“數據源=（本地）；初始目錄= testForDLL；集成安全性= SSPI；持久安全性信息= False；” QUERY =“ SELECT * FROM TBL2 WHERE id = 1” /> ROOT>

我想從第二列加載值，並使用它創建一個XDOCUMENT。 到目前為止，我有此代碼：

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
            }

問任何您想幫助我的事情。

我想我用這段代碼解決了問題。

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;
            }

您認為這是最好的解決方案嗎？
