C#实现xml文件的读取与写入简单实例

本文实例讲述了c#实现xml文件的读取与写入方法。分享给大家供大家参考。具体如下：

//datatable dateset 都可以用来读取xml数据和写入xml数据
protected voidbutton1_click(object sender, eventargs e)
{
  datatabledt = new datatable("employee");
  datacolumndcid = new datacolumn("id", typeof(string));
  datacolumndcname = new datacolumn("name", typeof(string));
  datacolumndcage = new datacolumn("age", typeof(string));
  datacolumndcdept = new datacolumn("dept", typeof(string));
  dt.columns.addrange(new datacolumn[] {dcid, dcname, dcage, dcdept });
  datarowdr = dt.newrow();
  dr["id"]= "3";
  dr["name"]= "chen";
  dr["age"]= "21";
  dr["dept"]= "技术部";
  dt.rows.add(dr);
  datasetds2 = new dataset();
  ds2.tables.add(dt);
  datasetds = new dataset();
  ds.readxml(server.mappath("employee.xml"));
  ds.merge(ds2);//合并数据
  ds.writexml(server.mappath("employee.xml"));
  page.clientscript.registerstartupscript(gettype(), "", "alert('写入成功')",true);
}
protected voidbutton2_click(object sender, eventargs e)
{
  datasetds = new dataset();
  ds.readxml(server.mappath("employee.xml"));
  gridview1.datasource = ds;
  gridview1.databind();
}

希望本文所述对大家的c#程序设计有所帮助。
