I want to use NameValueCollection in windows phone 8, but I can not see this option in WP8 SDK. Can you help me please?
This function has been removed.
But a query can be manipulated using parsing and a SortedDictionary. i.e. This snippet sorts a query string:
public string sortQuery(string myUrl)
{
string url = myUrl.Substring(0, myUrl.IndexOf("?") + 1);
string q = myUrl.Substring(myUrl.IndexOf("?") + 1);
string[] pr = q.Split('&');
SortedDictionary<string,string> d = new SortedDictionary<string,string>();
foreach (string s in pr)
{
string[] prm = s.Split('=');
string key = prm[0];
string value = "";
if (prm.Length > 1) { value = "=" + prm[1]; }
d.Add(key, value);
}
string result = "";
foreach (var k in d.Keys)
{
result += k + d[k] + "&";
}
result = result.Substring(0, result.Length - 1);
return url + result;
}

i am creating a wcf service for Pay u Money I wrote same code like asp.net c# for Pay u Money, but using HttpWebRequest I'm facing this error:
SORRY! We were unable to process your payment
Same code I tried in simple asp.net c# and there working fine. Here I don't know what goes wrong, how could I solve this?
enter code here

I'm confused with my first Java assignment! I followed my teacher's pseudocode and tried to make it look like the example we did in class, but I'm getting an error saying "String index out of range: -1" I looked around but really didn't find the error happening in this way, or maybe I just couldn't figure out how to use that information to solve my problem.
Can someone help me out?

Thanks in Advance...
It looks like you are never closing your reader, you need to call xr.Close() at some point. Or as Johan suggested, wrap it in a using statement:
using (XmlReader xr = XmlReader.Create(Userpath, xrs))
{
//Setting the Root element
XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "Registration";
xRoot.IsNullable = true;
XmlSerializer deserializer = new XmlSerializer(typeof(Registration), xRoot);
Registration UserDetails = (Registration)deserializer.Deserialize(xr);
Users = UserDetails.Users;
foreach (var varuser in Users)
{
if (username == varuser.Username)
{
strUsername = varuser.Username;
return true;
}
}
if (strUsername == "")
{
//here iam trying to add a node to the xml
using (StreamWriter sw = new StreamWriter(File.Create(Userpath)))
{
sw.Write("<User><Firstname>"
+ firstname + "</Firstname><Lastname>"
+ lastname + "</Lastname><Country>"
+ country + "</Country><Purchasedate>"
+ purchasedate + "</Purchasedate><Emailaddress>"
+ emailaddress + "</Emailaddress><Username>"
+ username + "</Username><Password>"
+ password + "</Password></User>");
}
return false;
}
}
Also another note: I notice your method is named ReadXML, yet you are also writing XML in this method. This can be confusing, are you reading or writing? Part of your issue may also be that you are opening the file for reading, and then creating the file for writing?? I have not dealt with the C# Xml libs before but something doesn't seem right here. You might consider breaking this down more.
I'm going to rewrite the application from Monotouh to Monodroid application for android. Correct me if I'm wrong. The logic remains the same as in MonoTouch or change anything? If something changes, please tell me, what?
As far as I understand, only GIU changes. Thanks in advance!

I think you should read this.
In brief - you can reuse application logic that not depends on platform-specific parts, so working with database/server can be shared between MonoTouch and Mono for Android.
I have a string of say 2000 characters how can I split the screen into 70 characters and insert newline for each 70 lines I have tried for first 70 characters and works fine as follow :
Dim notes As String = ""
If (clmAck.Notes.Count > 70) Then
notes = clmAck.Notes.Insert(70, Environment.NewLine)
Else
I wrote this now for fun:
public static class StringExtension
{
public static string InsertSpaced(this string stringToinsertInto, int spacing, string stringToInsert)
{
StringBuilder stringBuilder = new StringBuilder(stringToinsertInto);
int i = 0;
while (i + spacing < stringBuilder.Length)
{
stringBuilder.Insert(i + spacing, stringToInsert);
i += spacing + stringToInsert.Length;
}
return stringBuilder.ToString();
}
}
[TestCase("123456789")]
public void InsertNewLinesTest(string arg)
{
Console.WriteLine(arg.InsertSpaced(2,Environment.NewLine));
}
It's C#, but should be easy to translate:
string notes = "";
var lines = new StringBuilder();
while (notes.Length > 0)
{
int length = Math.Min(notes.Length, 70);
lines.AppendLine(notes.Substring(0, length));
notes = notes.Remove(0, length);
}
notes = lines.ToString();
