我试图在我的应用程序中使用 Webservice。我正在将我的数据转换为 XML 元素并且正在传递,但我的智能感知没有检测到 XmlDocument。我的代码是
[WebMethod]
public XmlElement GetUserDetails(string userName)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ToString());
con.Open();
SqlCommand cmd = new SqlCommand("select * from UserInformation where UserName like @userName+'%'", con);
cmd.Parameters.AddWithValue("@userName", userName);
cmd.ExecuteNonQuery();
SqlDataAdapter da = new SqlDataAdapter(cmd);
// Create an instance of DataSet.
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
// Return the DataSet as an XmlElement.
XmlDataDocument xmldata = new XmlDataDocument(ds);
XmlElement xmlElement = xmldata.DocumentElement;
return xmlElement;
}
