本文提供了两个C#函数，用于实现XML与DataTable之间的相互转换。这些函数可以帮助开发者轻松地将数据表转换为XML字符串，或将XML字符串解析为数据表。

C#中XML与datatable互换的两个函数：

private string ConvertDataTableToXML(DataTable xmlDS)
{
MemoryStream stream = null;
XmlTextWriter writer = null;
try
{
stream = new MemoryStream();
writer = new XmlTextWriter(stream, Encoding.Default);
xmlDS.WriteXml(writer);
int count = (int)stream.Length;
byte[] arr = new byte[count];
stream.Seek(0, SeekOrigin.Begin);
stream.Read(arr, 0, count);
UTF8Encoding utf = new UTF8Encoding();
return utf.GetString(arr).Trim();
}
catch
{
return String.Empty;
}
finally
{
if (writer != null) writer.Close();
}
}
private DataSet ConvertXMLToDataSet(string xmlData)
{
StringReader stream = null;
XmlTextReader reader = null;
try
{
DataSet xmlDS = new DataSet();
stream = new StringReader(xmlData);
reader = new XmlTextReader(stream);
xmlDS.ReadXml(reader);
return xmlDS;
}
catch (Exception ex)
{
string strTest = ex.Message;
return null;
}
finally
{
if (reader != null)
reader.Close();
}
}
