Url with = sign and get value from it

I'm trying to get multiple value from URL. But i don't know how Url is getting multiple = sign. That is why i am unable to get it using the querystring. So i am accessing the full URL and trying to get the value from it but i am unable to remove % sign from values.
Here is my code.
string fullUrl = Request.Url.AbsoluteUri.ToString();
string str = fullUrl.Substring(fullUrl.LastIndexOf("Amount"));
Here fullUrl has the value as below:-
fullUrl =
"http://localhost:10372/Customer/Success.aspx?URL=Amount=10&Name=Shami%20%20Sheikh&EmailOfPayer=ansitshami911#gmail.com&bussness=61339393592016_Preevet&CompanyName=Shami%20Sheikh&PaymentDate=07/03/2018%2015:50:48&SecuritiesandComplianceFee=0.47&BackmyUri=http://localhost:11181/Payment.aspx&phone=1234567891&Cardnumber=973638353835&Country=198&St=354&Other=&city=Delhi&Address=Delhi&ZipCode=201301&EmailOfReceiver=ansitshami911#gmail.com&Planrateforaccount=40&Planrateforcard=60&Planrateforcheck=2018&PlanYear=2018"
str variable has the value as below
str =
Amount=10&Name=Shami%20%20Sheikh&EmailOfPayer=ansitshami911#gmail.com&bussness=61339393592016_Preevet&CompanyName=Shami%20Sheikh&PaymentDate=07/03/2018%2015:50:48&SecuritiesandComplianceFee=0.47&BackmyUri=http://localhost:11181/Payment.aspx&phone=1234567891&Cardnumber=973638353835&Country=198&St=354&Other=&city=Delhi&Address=Delhi&ZipCode=201301&EmailOfReceiver=ansitshami911#gmail.com&Planrateforaccount=40&Planrateforcard=60&Planrateforcheck=2018&PlanYear=2018
Here is my code to get the value from URL :-
string s = str;
String[] arr = s.Split('&');
var Namearr = from word in arr
where word.StartsWith("Name")
select word;
foreach (var item1 in Namearr)
{
string str1 = item1.ToString();
string[] strArr = str1.Split('=');
string Name = strArr[1];
}
But the value assigned in variable is Name = "Shami%20%20Sheikh"
Now when i am trying to get the value of Name it returns the value with % sign .
How can i get the actual value from URl?

You can get query string values that are already processed using:
Request.QueryString["Name"]

By using the following code you will get the all the queryString parameters from where you can find your element queryString parameter and it's value.
foreach (string key in Request.QueryString.AllKeys) {
Response.Write("Key: " + key + " Value: " + Request.QueryString[key]);
}

I think you're looking for System.Uri.UnescapeDataString(Name)
https://msdn.microsoft.com/en-us/library/system.uri.unescapedatastring(v=vs.110).aspx

By using server.UrlDecode it works fine.
string fullUrl = Server.UrlDecode(Request.Url.AbsoluteUri.ToString());

How to extract an url from a String in C#

I have this string :
"<figure><img
src='http://myphotos.net/image.ashx?type=2&image=Images\\2\\9\\11\\12\\3\\8\\4\\7\\685621455625.jpg'
href='JavaScript:void(0);' onclick='return takeImg(this)'
tabindex='1' class='myclass' width='55' height='66' alt=\"myalt\"></figure>"
How can I retrieve this link :
http://myphotos.net/image.ashx?type=2&image=Images\\2\\9\\11\\12\\3\\8\\4\\7\\685621455625.jpg
All string are the same type so somehow I need to get substring between src= and href. But I don't know how to do that. Thanks.

If you parse HTML don't not use string methods but a real HTML parser like HtmlAgilityPack:
var doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html); // html is your string
var linksAndImages = doc.DocumentNode.SelectNodes("//a/#href | //img/#src");
var allSrcList = linksAndImages
.Select(node => node.GetAttributeValue("src", "[src not found]"))
.ToList();

You can use regex:
var src = Regex.Match("the string", "<img.+?src=[\"'](.+?)[\"'].*?>", RegexOptions.IgnoreCase).Groups[1].Value;

In general, you should use an HTML/XML parser when parsing a value from HTML code, but with a limited string like this, Regex would be fine.
string url = Regex.Match(htmlString, #"src='(.*?)'").Groups[1].Value;

If your string is always in same format, you can easily do this like so :
string input = "<figure><img src='http://myphotos.net/image.ashx?type=2&image=Images\\2\\9\\11\\12\\3\\8\\4\\7\\685621455625.jpg' href='JavaScript:void(0);' onclick='return takeImg(this)' tabindex='1' class='myclass' width='55' height='66' alt=\"myalt\"></figure>";
// link is between ' signs starting from the first ' sign so you can do :
input = input.Substring(input.IndexOf("'")).Substring(input.IndexOf("'"));
// now your string looks like : "http://myphotos.net/image.ashx?type=2&image=Images\\2\\9\\11\\12\\3\\8\\4\\7\\685621455625.jpg"
return input;

string str = "<figure><imgsrc = 'http://myphotos.net/image.ashx?type=2&image=Images\\2\\9\\11\\12\\3\\8\\4\\7\\685621455625.jpg'href = 'JavaScript:void(0);' onclick = 'return takeImg(this)'tabindex = '1' class='myclass' width='55' height='66' alt=\"myalt\"></figure>";
int pFrom = str.IndexOf("src = '") + "src = '".Length;
int pTo = str.LastIndexOf("'href");
string url = str.Substring(pFrom, pTo - pFrom);
Source :
Get string between two strings in a string

Q is your string in this case, i look for the index of the attribute you want (src = ') then I remove the first few characters (7 including spaces) and after that you look for when the text ends by looking for '.
With removing the first few characters you could use .IndexOf to look for how many to delete so its not hard coded.
string q =
"<figure><img src = 'http://myphotos.net/image.ashx?type=2&image=Images\\2\\9\\11\\12\\3\\8\\4\\7\\685621455625.jpg' href = 'JavaScript:void(0);' onclick = 'return takeImg(this)'" +
"tabindex = '1' class='myclass' width='55' height='66' alt=\"myalt\"></figure>";
string z = q.Substring(q.IndexOf("src = '"));
z = z.Substring(7);
z = z.Substring(0, z.IndexOf("'"));
MessageBox.Show(z);
This is certainly not the most elegant way (look at the other answers for that :)).

Parse a string in C#

I've the following string that I get from a method. I would like to parse it and make pairs. The order of input string will not change.
INPUT:
ku=value1,ku=value2,ku=value3,ku=value4,ku=value5,lu=value6,lu=value7,lu=value8,lu=value9
OUTPUT
Name value1
Title value2
School value3
.
.
.
Age value9
I think I can read through the string and assign value to the left hand side as I go and so on. However, I am very new to C#.

Use string.Split and split imput string to list key-value pair then split each pair to key and value. Tahts all.

You can do something like this:
void Main()
{
string str = "ku=value1,ku=value2,ku=value3,ku=value4,ku=value5,lu=value6,lu=value7,lu=value8,lu=value9";
var tempStr = str.Split(',');
var result = new List<KeyValue>();
foreach(var val in tempStr)
{
var temp = val.Split('=');
var kv = new KeyValue();
kv.Name = temp[0];
kv.Value = temp[1];
result.Add(kv);
}
}
public class KeyValue
{
public string Name {get;set;}
public string Value{get;set;}
}

If you don't need the first part you can do this using String split as follow
Split String on , using String.Split method creating sequence of string {"ku=value1","ku=value2",...}
Use Linq's Select method to apply an additional transformation
Use Split again on each item on the '=' character
Select the item to the right of the '=', at index 1 of the newly split item
Loop through everything and print your results
Here's the code
var target = "ku=value1,ku=value2,ku=value3,ku=value4,ku=value5,lu=value6,lu=value7,lu=value8,lu=value9";
var split = target.Split(',').Select(a=>a.Split('=')[1]).ToArray();
var names = new[]{"Name","Title","School",...,"Age"};
for(int i=0;i<split.Length;i++)
{
Console.WriteLine(names[i]+"\t"+split[i]);
}
If you want to find out more about how to use these methods you can look at the MSDN documentation for them :
String.Split(char[]) Method
Enumerable.Select Method

I suggest to try this way. Split() plus regular expression
string inputString = "ku=value1,ku=value2,ku=value3,ku=value4,ku=value5,lu=value6,lu=value7,lu=value8,lu=value9";
string pattern = "(.*)=(.*)";
foreach(var pair in inputString.Split(','))
{
var match = Regex.Match(pair,pattern);
Console.WriteLine(string.Format("{0} {1}",match.Groups[1].Value, match.Groups[2].Value));
}

C# IndexOf (Read from resource.resx)

I created config file with some texts and this file i added to resource.resx. Now i created string for this text.
// String will be contains all texts from resource file
string TextFromResources = Resource.konfigurace;
TextFromResources - > View:
#################
# Settings
#################
RealmID = 1
#################
For next step i need use function "IndexOf".
int value = TextFromConfig.IndexOf("RealmID");
value = TextFromConfig.IndexOf('=');
value2 = TextFromConfig.IndexOf("/r/n");
RealmID = int.Parse(TextFromConfig.Substring(value, value2));
I need that realmID return me int value "1", but now its return me nothing. Please, can you help with my problem?
If index will be correctly so it will be return me value "1" nothing more.

Ah, the substring needs to start after value. Here's a simplified version of your example that works for me:
var text = "RealmID = 1\r\n";
var value = text.IndexOf('=');
var value2 = text.IndexOf("\r\n", value);
var id = int.Parse(text.Substring(value + 1, value2 - value));
Also, I modified the IndexOf call for getting value2 so that it searches for "\r\n" after the location of '='.
Another option is to use a regular expression to find the RealmID value.
var regex = new Regex(#"RealmID = (\d+)");
var match = regex.Match(text);
int realmID = int.Parse(match.Groups[1].Value);

Splitting a string which contain multiple symbols to get specific values

I cannot believe I am having trouble with this following string
String filter = "name=Default;pattern=%%;start=Last;end=Now";
This is a short and possibly duplicate question, but how would I split this string to get:
string Name = "Default";
string Pattern = "%%" ;
string start = "Last" ;
string end = "Now" ;
Reason why I ask is my deadline is very soon, and this is literally the last thing I must do. I'm Panicking, and I'm stuck on this basic command. I tried:
pattern = filter.Split(new string[] { "pattern=", ";" },
StringSplitOptions.RemoveEmptyEntries)[1]; //Gets the pattern
startDate = filter.Split(new string[] { "start=", ";" },
StringSplitOptions.RemoveEmptyEntries)[1]; //Gets the start date
I happen to get the pattern which I needed, but as soon as I try to split start, I get the value as "Pattern=%%"
What can I do?
Forgot to mention
The list in this string which needs splitting may not be in any particular order . this is a single sample of a string which will be read out of a stringCollection (reading these filters from Properties.Settings.Filters

Using string.Split this is a two stage process.
In the first case split on ; to get an array of keyword and value pairs:
string[] values = filter.Split(';');
Then loop over the resultant list splitting on = to get the keywords and values:
foreach (string value in values)
{
string[] pair = value.Split('=');
string key = pair[0];
string val = pair[1];
}

String filter = "name=Default;pattern=%%;start=Last;end=Now";
string[] temp = filter.Split('=');
string name = temp[1].Split(';')[0];
string pattern = temp[2].Split(';')[0];
string start = temp[3].Split(';')[0];
string end = temp[4].Split(';')[0];

This should do the trick:
string filter = "name=Default;pattern=%%;start=Last;end=Now";
// Make a dictionary.
var lookup = filter
.Split(';')
.Select(keyValuePair => keyValuePair.Split('='))
.ToDictionary(parts => parts[0], parts => parts[1]);
// Get values out of the dictionary.
string name = lookup["name"];
string pattern = lookup["pattern"];
string start = lookup["start"];
string end = lookup["end"];

The start date ends up at the thrird position in the array:
startDate = filter.Split(new string[] { "start=", ";" }, StringSplitOptions.RemoveEmptyEntries)[2];
Instead of splitting the string once for each value, you might want to split it into the separate key-value pairs, then split each pair:
string[] pairs = filter.Split(';');
string[] values = pairs.Select(pair => pair.Split('=')[1]).ToArray();
string name = values[0];
string pattern = values[1];
string start = values[2];
string end = values[3];
(This code of course assumes that the key-value pairs always come in the same order.)
You could also split the string into intersperced array, so that every other item is a key or a value:
string[] values = filter.Split(new string[] { "=", ";" }, StringSplitOptions.None);
string name = values[1];
string pattern = values[3];
string start = values[5];
string end = values[7];
Edit:
To handle key-values in any order, make a lookup from the string, and pick values from it:
ILookup<string, string> values =
filter.Split(';')
.Select(s => s.Split('='))
.ToLookup(p => p[0], p => p[1]);
string name = values["name"].Single();
string pattern = values["pattern"].Single();
string start = values["start"].Single();
string end = values["end"].Single();
You can use SingleOrDefault if you want to support values being missing from the string:
string name = values["name"].SingleOrDefault() ?? "DefaultName";
The lookup also supports duplicate key-value pairs. If there might be duplicates, just loop through the values:
foreach (var string name in values["name"]) {
// do something with the name
}

Well I tried something like this:
var result = "name=Default;pattern=%%;start=Last;end=Now".Split(new char[]{'=',';'});
for(int i=0;i<result.Length; i++)
{
if(i%2 == 0) continue;
Console.WriteLine(result[i]);
}
and the output is:
Default
%%
Last
Now
Is this what you want?

You see, the thing is now that your Split on filter a second time still starts from the beginning of the string, and it matches against ;, so since the string hasn't changed, you still retrieve previous matches (so your index accessor is off by X).
You could break this down into it's problem parts, such that:
var keyValues = filter.Split(';');
var name = keyValues[0].Split('=')[1];
var pattern = keyValues[1].Split('=')[1];
var start = keyValues[2].Split('=')[1];
var end = keyValues[3].Split('=')[1];
Note that the above code is potentially prone to error, and as such should be properly altered.

You can use the following:
String filter = "name=Default;pattern=%%;start=Last;end=Now";
string[] parts = filter.Split(';');
string Name = parts[0].Substring(parts[0].IndexOf('=') + 1);
string Pattern = parts[1].Substring(parts[1].IndexOf('=') + 1);
string start = parts[2].Substring(parts[2].IndexOf('=') + 1);
string end = parts[3].Substring(parts[3].IndexOf('=') + 1);

Use this:
String filter = "name=Default;pattern=%%;start=Last;end=Now";
var parts = filter.Split(';').Select(x => x.Split('='))
.Where(x => x.Length == 2)
.Select(x => new {key = x[0], value=x[1]});
string name = "";
string pattern = "";
string start = "";
string end = "";
foreach(var part in parts)
{
switch(part.key)
{
case "name":
name = part.value;
break;
case "pattern":
pattern = part.value;
break;
case "start":
start = part.value;
break;
case "end":
end = part.value;
break;
}
}
If you don't need the values in named variables, you only need the second line. It returns an enumerable with key/value pairs.
My solution has the added benefits that the order of those key/value pairs in the string is irrelevant and it silently ignores invalid parts instead of crashing.

I found a simple solution on my own too. Most of your answers would have worked if the list would have been in the same order every single time, but it wont be. the format however, will always stay the same. The solution is a simple iteration using a foreach loop, and then checking if it starts with a certain word, namely, the word I am looking for, like Name, Pattern etc.
Probably not the most cpu efficient way of doing it, but it is C# for dummies level. Really brain-fade level.
Here is my beauty.
foreach (string subfilter in filter.Split(';')) //filter.Split is a string [] which can be iterated through
{
if (subfilter.ToUpper().StartsWith("PATTERN"))
{
pattern = subfilter.Split('=')[1];
}
if (subfilter.ToUpper().StartsWith("START"))
{
startDate = subfilter.Split('=')[1];
}
if (subfilter.ToUpper().StartsWith("END"))
{
endDate = subfilter.Split('=')[1];
}
}
