以上是我xml的一个例子，我用的asp.net在后台用dataset分别装了以上是三个表，并且建立了关系，但是在导出xml的只能导出第一个表，大家帮我看看哪里出问题了。
- C# code
string sqlBaseInfo = "select * from BaseInfo where BaseInfo_Id = 14"; dt = DBHelper.getDataTable(sqlBaseInfo, null); dt.TableName = "BaseInfo"; ds.Tables.Add(dt.Copy()); //---------------------------------------------------------- string sqlInput = "select * from Input where BaseInfo_Id = 14"; DataTable dtInput = DBHelper.getDataTable(sqlInput, null); dtInput.TableName = "Input"; string Input_Id = dtInput.Rows[0]["Input_Id"].ToString(); ds.Tables.Add(dtInput.Copy()); //--------------------------------------------------------- string sqlBase = "select * from Base where Input_Id = " + Input_Id + ""; dt = DBHelper.getDataTable(sqlBase, null); dt.TableName = "Base"; ds.Tables.Add(dt.Copy()); DataRelation custOrderRelation = ds.Relations.Add("Input-Base", ds.Tables["Input"].Columns["Input_Id"], ds.Tables["Base"].Columns["Input_Id"]); DataRelation custOrderRelation1 = ds.Relations.Add("BaseInfo-Input", ds.Tables["BaseInfo"].Columns["BaseInfo_Id"], ds.Tables["Input"].Columns["BaseInfo_Id"]);这里是我后台的源码，
- C# code
public static bool CDataToXmlFile(DataTable dt, string xmlFilePath) { if ((dt != null) && (!string.IsNullOrEmpty(xmlFilePath))) { // string path = HttpContext.Current.Server.MapPath(xmlFilePath); string path = xmlFilePath; MemoryStream ms = null; XmlTextWriter XmlWt = null; try { ms = new MemoryStream(); //根据ms实例化XmlWt XmlWt = new XmlTextWriter(ms, Encoding.Unicode); //获取ds中的数据 dt.WriteXml(XmlWt); int count = (int)ms.Length; byte[] temp = new byte[count]; ms.Seek(0, SeekOrigin.Begin); ms.Read(temp, 0, count); //返回Unicode编码的文本 UnicodeEncoding ucode = new UnicodeEncoding(); //写文件 StreamWriter sw = new StreamWriter(path); sw.WriteLine("<?xml version=" + '"' + "1.0" + '"' + " encoding=" + '"' + "utf-8" + '"' + "?>"); sw.WriteLine(ucode.GetString(temp).Trim()); sw.Close(); return true; } catch (System.Exception ex) { throw ex; } finally { //释放资源 if (XmlWt != null) { XmlWt.Close(); ms.Close(); ms.Dispose(); } } } else { return false; } }
