[英]Create an XML from a DataTable
Using C# : I want to convert this table into XML. 使用C#:我想将此表转换为XML。 Please ignore the mistakes in row names .
请忽略行名中的错误 。 This is test data.
这是测试数据。 I have given sample of two columns converted to xml and the corresponding rows as attributes .
我给出了两列转换为xml的示例,并将相应的行作为属性。 But i actually want for all columns.
但是我实际上想要所有列。 This is a Datatable.
这是一个数据表。

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();
}
This worked great for me. 这对我来说很棒。 Thanks stackoverflow.
谢谢stackoverflow。
DataTable
s are designed to iterate over rows, not columns like you have. DataTable
旨在迭代行,而不是像您那样的列。 There's nothing built-in to persist a DataTable
in column-major order. 没有内置功能可以按列优先顺序持久保存
DataTable
。 You're going to have use custom code. 您将使用自定义代码。 Pseudo-code would be something like:
伪代码将类似于:
foeeach(DataColumn)
if(name != "Name")
output column header
foreach(DataRow)
output row value
you can try using this 你可以尝试使用这个

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