using HttpWebResponse to get POST variables

[David Billson]

Hi all,

Fairly straight forward problem. I have a Post using HttpWebRequest
that posts data to a server. That server then posts data back to me.
Posting the data's not a problem, however I'm wondering if there is an
easy way to read back the variables that are returned. If not, I'm
left creating a parse routine which is not the end of the world but I
just want to be as programatically correct as I can be.

Code:

StreamReader sr = new StreamReader(HttpWResponse.GetResponseStream(),
System.Text.Encoding.ASCII);
//Convert the stream to a string
string s = sr.ReadToEnd();
sr.Close();
Response.Write(s);

RETURNS:

s ="trnApproved=1&trnId=10000843&messageId=1&messageText=Approved&authCode=TEST&errorType=N&errorFields=&avsProcessed=0&avsId=0&avsResult=0&avsAddrMatch=0&avsPostalMatch=0&avsMessage=Address+Verification+not+performed+for+this+transaction%2E"

I'd just like a way to read Request["trnApproved"] or
Request["messageText"] - Any ideas?

Thanks,
DB

I create a helper class , to strore the request array

using System;
using System.Collections;
using System.Collections.Specialized;

namespace Erymuzuan.WinContainer
{
/// <summary>
/// Summary description for BrowserInfo.
/// </summary>
public class BrowserInfo : NameObjectCollectionBase
{
/// <summary> </summary>
private DictionaryEntry m_de = new DictionaryEntry();

/// <summary>
/// ctor
/// </summary>
/// <example>
/// new BrowserInfo("myq=msa&sw=12&id=1232");
/// </example>
/// <param name="postData">query string pairs
/// </param>
public BrowserInfo(string postData)
{
string name;
string val;

foreach ( string s in postData.Split('&'))
{
name = s.Substring(0, s.IndexOf("=") );
val = s.Substring(s.IndexOf("=") + 1 , s.Length - (name.Length + 1));

// add it
BaseAdd(name, val);
}

}
/// <summary> Gets a key-and-value pair (DictionaryEntry) using an
index.</summary>
public DictionaryEntry this[ int index ]
{
get
{
m_de.Key = BaseGetKey(index);
m_de.Value = BaseGet(index);
return( m_de );
}
}

//
/// <summary> Gets or sets the value associated with the specified
key.</summary>
public string this[ string key ]
{
get { return( BaseGet( key ).ToString() ); }
set { BaseSet( key, value ); }
}

//
/// <summary> Gets a String array that contains all the keys in the
collection.</summary>
public String[] AllKeys
{
get { return( this.BaseGetAllKeys() ); }
}

//
/// <summary> Gets an Object array that contains all the values in the
collection.</summary>
public Array AllValues
{
get { return( this.BaseGetAllValues() ); }
}

//
/// <summary> Gets a value indicating if the collection contains keys that
are not null.</summary>
public Boolean HasKeys
{
get { return( this.BaseHasKeys() ); }
}


/// <summary>
/// Adds an entry to the collection.
/// </summary>
/// <param name="key"></param>
/// <param name="value"></param>
public void Add( String key, Object value )
{
this.BaseAdd( key, value );
}



}// class
}

Since you are programatically going to another web page, chances are you are
doing this to get data? If so, and if you have control over it - the server
you are calling - should return XML. That way all your data will be nice and
organized when it do a GetResponseStream(). Food for thought...
