C# 从数据表创建XML

使用C：我想把这个表转换成XML。请忽略行名称中的错误。这是测试数据。我给出了两个转换为xml的列的示例，以及作为属性的相应行。但实际上我想要所有的专栏。这是一个数据表

DataTables被设计为对行进行迭代，而不是像您现在这样对列进行迭代。没有任何内置功能可以按列主顺序持久化数据表。您将不得不使用自定义代码。伪代码类似于：

foeeach(DataColumn)
  if(name != "Name")
    output column header
    foreach(DataRow) 
      output row value

你可以试着用这个

这对我很有效。谢谢stackoverflow。

*在第二个xelement中。这是打字错误Use DataTable.WriteXml我必须跳过第一列。如果有人能给我提供代码，那就太好了。我添加了跳过“名称”列，但你必须自己做一些工作。如果你有特定的问题，你可以把它们作为新问题发布在这里，但我怀疑你是否会找人为你写下全部内容。

DataTable youdatatable = GetData();
System.IO.StringWriter writer = new System.IO.StringWriter();
 youdatatable.WriteXml(writer, XmlWriteMode.WriteSchema, true);
 PrintOutput(writer);

public static string ToXml(this DataTable table, int metaIndex = 0)
{
    XDocument xdoc = new XDocument(
        new XElement(table.TableName,
            from column in table.Columns.Cast<DataColumn>()
            where column != table.Columns[metaIndex]
            select new XElement(column.ColumnName,
                from row in table.AsEnumerable()
                select new XElement(row.Field<string>(metaIndex), row[column])
                )
            )
        );

    return xdoc.ToString();
}
