使用LINQ将数据表转换为XML [英] Datatable to XML using LINQ

问题描述

我正在编写一种使用LINQ转换数据表的方法.我能够将数据表直接转换为XML，如下所示:

I am writing a method to convert datatable using LINQ. I was able to get straight forward conversion from datatable to XML as below:

XDocument doc = new XDocument(new XDeclaration("1.0","UTF-8","yes"),
   new XElement("pfolios", from p in dt.AsEnumerable()
    select new XElement("pfolio",
        new XAttribute("ID", p.ID), 
        new XAttribute("Date", p.Date),
        new XAttribute("Expired", p.Expiry))));

但是我需要一些帮助来编写一个方法，该方法将具有任意列数的数据表作为输入并将这样的内容写入xml:这个lamdba表达式不起作用，但是我正在寻找一种简化方法.预先感谢您的帮助

but I need some help to write a method, that takes datatable with any number of columns as input and write to xml something like this: This lamdba expression does not work but I am looking for a way to simplify this. Thanks in advance for your help

  XElement xe = new XElement("pfolios", from p in dt.AsEnumerable()
             select new XElement("pfolio",dt.AsEnumerable().ToList().ForEach(dc=> dt.Columns) 
new XAttribute(dc.ColumnName, p[dc.ColumnName])));

推荐答案

您正在寻找

table.AsEumerable().Select(row =>
    new XElement("row",
        table.Columns.Cast<DataColumn>().Select(col =>
            new XAttribute(col.ColumnName, row[col])
        )
    )
)
