ASP.Net输出纯XML数据

有时asp.net文件输出纯XML数据很有用，这时的asp.net文件就相当于一个WebService，输出XML文档也很简单，分以下几部
1、设置输出类型-Response.ContentType = "text/xml";
2、设置字符集－Response.Charset = "GB2312";
3、清空输入内容－Response.Clear();
4、构造XML内容并输出－Response.Write(...)
最后结束余下的输出Response.End(),

DataSet ds = new DataSet();
DataTable table = new DataTable("Item");
table.Columns.Add("Name", typeof(string));
table.Columns.Add("Price", typeof(string));

DataRow r = table.NewRow();
r[0] = "huzhen";
r[1] = "huzhen";
table.Rows.Add(r);

r = table.NewRow();
r[0] = "huzhen";
r[1] = "huzhen";
table.Rows.Add(r);

ds.Tables.Add(table);
Response.ContentType = "text/xml";
Response.Charset = "GB2312";
Response.Clear();
Response.Write("<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n " + ds.GetXml());
Response.End();
