利用WebClient获取远程数据（仅做备份）

public DataSet GetData(string httpUrl)
{
string xmlPath = @"http地址"; // 该地址不能包含中文
DataSet ds = new DataSet();
WebClient wc = new WebClient();
byte[] bt = wc.DownloadData(xmlPath);
XmlDocument xd = new XmlDocument();

string source = Byte2String(bt);

xd.LoadXml(source);

XmlNodeReader xnr = new XmlNodeReader(xd);

ds.ReadXml(xnr);

DataTable dt = ds.Tables[0];

this.DataGrid1.DataSource = ds;

this.DataGrid1.DataBind();

return ds;

}

public static string Byte2String(byte[] bt)

{

System.Text.Encoding encoding = System.Text.Encoding.GetEncoding("gb2312");

string str = encoding.GetString(bt);

return str;

}
