Consuming a Web Service XML using C#

I am trying to make use of a Zip Code Web Service which recieves a 5 digit zip code and returns City, State, Area Code, etc...

The web service is located here:

In Visual Studio 2003 (using c#) I have setup the Web Reference, added a text box, and called the Web Service on a button click no problem.

The problem is what to do with the information that I get back.  From the error messages I have been recieving (when I don't add a .ToString()) it seems that the information being returned to me is in the format System.Xml.XmlNode

The gist of my code is something like: lblMsg.Text = zip_code.GetInfoByZIP(tbZipCode.Text).InnerXml;

using InnerXml gets me all the information, but all smushed together ala "Beverly HillsCA90210310P"

I need to be able to do two things with this input
1. Bind the XML to a DataSet
2. Read each piece/node of the XML seperatley

The best thing to do is to create a dataset and then you can use ReadXml() and if you have the data in a string that you get back then you can use a StringReader to read the string into the Dataset and have it create the table.

When you have that then the dataset can be referenced by Tables[0][Columnname], etc.

Let me know if I can help more.

I meant to say, You can do, not necessarily the Best thing to do.

Sorry for the delay in responding...I have been away with a family issue.

Would it be possible for you to please supply some code to show me exactly what you are talking about?

You can use a DataSet to do both items that you are looking to do.

using System.IO;
using System.Data;


string xml = zip_code.GetInfoByZIP(tbZipCode.Text).InnerXml;

StringReader sr = new StringReader(xml);

DataSet ds = new DataSet();

string zipCode = ds.Tables[0]["ZIP"].ToString();


Is that what you are looking for?  And you can also bind this to a datagrid or whatever, by using the DataSet that gets created in the ReadXml();

Muchos Gracias dbaduck,

That's exatly what I was looking for to bridge the gap between the xml feed and making use of the data in .net

One Correction for prosperties sake:
string zipCode = ds.Tables[0]["ZIP"].ToString();

didn't seem to be working, but this fixes the problem:

string zipCode = ds.Tables[0].Rows[0]["ZIP"].ToString();
