Dataset.ReadXml() - 주어진 인코딩의 문자가 잘못되었습니다

Question

다음 코드를 사용하여 xml 열의 sql 데이터베이스에 데이터 집합을 저장했습니다.

XmlDataDocument dd = new XmlDataDocument(dataset); 

및 SQL 매개 변수로이 XML 문서를 전달하여

param.value = new XmlNodeReader(dd); 

내가

using (SqlConnection con = new SqlConnection("Server=#####;Initial Catalog=#####;User ID=####;Pwd=########")) 
     { 
      using (SqlCommand com = new SqlCommand("select * from dbo.tbl_#####", con)) 
      { 
       using (SqlDataAdapter ada = new SqlDataAdapter(com)) 
       { 
        ada.Fill(dt); 
        MemoryStream ms = new MemoryStream(); 
        object contractXML1 = dt.Rows[0]["SCOXML1"]; 
        System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bf = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(); 
        bf.Serialize(ms, contractXML1); 
        ms.Seek(0, SeekOrigin.Begin); 
        ds.ReadXml(ms); 
       } 
      } 
     }

것처럼 XML은

다음 오류가 발생했습니다

루트 수준의 데이터가 잘못되었습니다. 1 호선, 6 번 위치.

아이디어가 있으십니까?

업데이트

난 다음에 코드를 변경했습니다. 내부에 모든 테이블이 추가 된 데이터 세트의 구조를 가져올 수 있습니다. 그러나 데이터는 아닙니다.

using (SqlConnection con = new SqlConnection("Server=###;Initial Catalog=####;User ID=###;Pwd=######")) 
     { 
      using (SqlCommand com = new SqlCommand("select * from dbo.tbl_####", con)) 
      { 
       using (SqlDataAdapter ada = new SqlDataAdapter(com)) 
       { 
        ada.Fill(dt); 
        MemoryStream ms = new MemoryStream(); 
        object contractXML1 = dt.Rows[0]["SCOXML1"]; 
        object schema = dt.Rows[0]["xmlSchemaHistory"]; 
        XmlSerializer xs = new XmlSerializer(typeof(object)); 
        xs.Serialize(ms, contractXML1); 
        ms.Position = 0; 
        xDoc.Load(ms); 
        xDocSc.LoadXml(schema.ToString()); 
        ds.ReadXmlSchema(new XmlNodeReader(xDocSc)); 
        ds.ReadXml(new XmlNodeReader(xDoc)); 
       } 
      } 
     } 

그러나 기본 xml 문서에 데이터가 있습니다. 어떤 아이디어?

Answer 1

왜 바이너리 포맷터를 사용하고 있습니까? 사실, 왜 당신은 전혀 연재 중입니까? XML 열이 SQL Server XML 데이터 형식을 사용하고 있지 않습니까? 그렇다면 SqlXml 데이터 형식을 사용하여 데이터를 검색해야합니다.

내가 전에 XML 컬럼 및 DataTables 함께 일한 적이 없어요. 나는 일반적으로이 목적으로 SqlDataReader을 사용한다. 그러나 힌트를 드릴 수 있습니다. SqlXml 개체를 얻은 후에는 XmlReader을 가져올 수 있습니다. 당신이 XmlReader을 가지고하면, 당신은 할 수 있습니다 :

DataTable dt = new DataTable("tableName"); 
dt.ReadXml(xmlReader); 

페이지의 "ReadXml(XmlReader)"와 "SqlXml.CreateReader Method"를.

Answer 2

이 어둠 속에서 샷을하지만 XML은 XML의 바이트 순서 마커 (BOM)를 가질 수 있으며, 이진 포맷터가 제대로 인코딩을 지정하지 않고 그것을 처리 할 수 ​​없다. 그렇다면 인코딩 된 스트림에 XML을 먼저로드해야 할 수 있습니다.
