【求助】【急】XML节点的简单设置

Question

我要输出的xml格式为
<?xml version="1.0" standalone="yes"?>
<TMapping xmlns="http://tempuri.org/TMapping.xsd">
  <TMappings>
    <ID>1</ID>
  <TMappings>
<TMapping>我现在输出的是
<?xml version="1.0" standalone="yes"?>
<DocumentElement xmlns="http://tempuri.org/TMapping.xsd">
  <TMappings>
    <ID>1</ID>
  <TMappings>
<TMapping>
我现在的代码是ToTable为datatable类型：              Row["ID"] = "1";
              ToTable.Rows.Add(Row);
            ToTable.DataSet.DataSetName = "qq";//报错
            ToTable.Prefix = "";
            ToTable.Namespace = "http://tempuri.org/TMapping.xsd";
            ToTable.TableName = "TMappings";
            ToTable.WriteXml(SFilename);请大家指教！谢谢

Answer 1

static void Main(string[] args)
        {
            DataSet ds = new DataSet();
            DataTable ToTable = new DataTable();
            ds.Tables.Add(ToTable);
            ToTable.Columns.Add("ID");
            DataRow Row = ToTable.NewRow();
            Row["ID"] = "1";
            ToTable.Rows.Add(Row);
            ToTable.DataSet.DataSetName = "TMapping";//报错 
            ToTable.Prefix = "";
            ds.Namespace = "http://tempuri.org/TMapping.xsd";
//            ToTable.Namespace = "http://tempuri.org/TMapping.xsd";
            ToTable.TableName = "TMappings";
            ToTable.WriteXml("test.xml"); 
        }
生成：
<?xml version="1.0" standalone="yes"?>
<TMapping xmlns="http://tempuri.org/TMapping.xsd">
  <TMappings>
    <ID>1</ID>
  </TMappings>
</TMapping>

Answer 2

<?xml version="1.0" standalone="yes"?>
<TMapping xmlns="http://tempuri.org/TMapping.xsd">  --DataSet的名称和xml命名空间
  <TMappings>                                       --DataTable的名称
    <ID>1</ID>                                      --列名和行值
  </TMappings>
</TMapping>
