I'm trying to format a String using the String.Format function, but my double quotes keep getting replaced by the HTML safe version of this (").
Needless to say this is not the result I would expect.
My current code looks like this
string String= String.Format("{0}: {{ name: \"{1}\"}}", node.Category, node.Name);
// Output ==> SomeCategory: { name: "SomeName" }
I've tried replacing the " by actual quotes in the output, but that also didn't work.Is there some voodoo I can use to fix this?
Thanks in advance!
This is not caused by String.Format(), more likely it is caused by whatever you use to view the data, or by something that happens before you view the data.
Judging from your format string it looks like you're trying to create a JSON string to return (possibly from a service). There is a big chance something will HTML encode your string on it's way to the client. The problem lays there, not in your string formatting, and thus trying to fix it there will not work.
Try to use HTML decode and encode
That way you can turn them in actual quotes.
HttpUtility.HtmlDecode

I need to send the value I receive from the model with this link, the proposalName field must be in quotes.How can I do it?
Here is my service url.
string path = string.Format("{ProposalId:{proposalId},ProposalName:{"proposalName"},VendorId:{vendorId}}",
Uri.EscapeDataString(proposalId.ToString()),
Uri.EscapeDataString(proposalName),
Uri.EscapeDataString(vendorId.ToString()));
You can simply put quotes around by escaping the quotes, like this -
string path = string.Format("{{0},ProposalName:\"{1}\",VendorId:{2}}",
Uri.EscapeDataString(proposalId.ToString()),
Uri.EscapeDataString(proposalName),
Uri.EscapeDataString(vendorId.ToString()));
As per your updated question, if you need to pass double quotes in URL, you need to encode it to %22
You can also use URI which allows a lot of flexibility with urls. For example -
Uri myUri = new Uri("http://google.com/search?hl=en&q=\"query with quotes\"");
Going with your example - Replace EscapeDataString with Uri.EscapeUriString. It will escape the chracter to form a valid URL. " will get replaced by %22
Some suggestions here and here-
Your problem exactlly in the {"1"} part. The double quotation mark " should be outside the {}, not inside them.
here is the fixed code.
string path = string.Format("{{0},ProposalName:\"{1}\",VendorId:{2}}",
Uri.EscapeDataString(proposalId.ToString()),
Uri.EscapeDataString(proposalName),
Uri.EscapeDataString(vendorId.ToString()));
or
string path = string.Format(#"{{0},ProposalName:""{1}"",VendorId:{2}}",
Uri.EscapeDataString(proposalId.ToString()),
Uri.EscapeDataString(proposalName),
Uri.EscapeDataString(vendorId.ToString()));
and if you are using C# 6 then you can write it as following
string path = $"{Uri.EscapeDataString(proposalId.ToString())},ProposalName:\"{Uri.EscapeDataString(proposalName)}\",VendorId:{Uri.EscapeDataString(vendorId.ToString())}";
This might do the trick for you
\"{1}\"
instead of
{"1"}
because you can put \ symbol to indicate escape sequence followed by a reserved characters
So
string.Format("{{{0},ProposalName:\"{1}\",VendorId:{2}}}",
I think escaping the quotes and placing them outside the brackets will work:
"{{0},ProposalName:\"{1}\",VendorId:{2}}"
Depending on the C# version, you can also do it like this, which I often think is an easier and cleaner way to do it:
string path = $"{proposalId},ProposalName:\"{proposalName}\",VendorId:{vendorId}";
You have two problems:
Wrong quotation (should be outside the braces {...} and escaped)
Incorrect { and } escape: {{ means just a single '{' in a formatting string
Should be
string path = string.Format("{{{0},ProposalName:\"{1}\",VendorId:{2}}}",
please, notice
escaped quotations \" which are outside {1}
tripled curly braces{{{ and }}}
Edit: in your edited question you have the same errors:
string format =
"http://mobile.teklifdosyam.com/VendorReport/GetListProposalService?&page=1&start=0&limit=10&filter=" +
"{{ProposalId:{0},ProposalName:\"{1}\",VendorId:{2}}}";
string path = string.Format(format,
Uri.EscapeDataString(proposalId.ToString()),
Uri.EscapeDataString(proposalName),
Uri.EscapeDataString(vendorId.ToString()));
please, notice escaped quotations \" which are outside the {1}, double '{{' and tripled '}}}'. When formatting you have to use numbers as place holders: so {"proposalName"} must be changed into {0}
In my Application there is a class that works with PdfSharp to generate some PDF reports. I specified output folder as a string with verbatim
string file_path = #"D:\Intranet\Students\DailyMarks\";
Also there is a StringBuilder that generates file name based on some ID and DateTime:
... sb.Append(document.Type); sb.Append(document.Id); sb.Append(DateTime.Now.ToShortString());
And finally I do the following
file_path + sb.toString();
But my Application cathes an exception. After debugging session I see that actually my file_path is
file_path = "D:\\Intranet\\Students\\DailyMarks\\...";
As I understand it happens after concatenation of origin file with StringBuilder's toString() call.
I tried to replace file_path string with something like this:
file_path = file_path.Replace(#"\\",#"\");
but it doesn't work. Where did I do wrong?
Probably this is caused by the DateTime.Now.ToShortString() method, which adds forbidden characters to the path (:).
It's totally fine.
"D:\\Intranet\\Students\\DailyMarks\\..." == #"D:\Intranet\Students\DailyMarks\..."
In regular string you need to escape slashes, in verbatim it's done automatically
Another similar situation I faced today was about sending Japanese 「：」 (colon with whole inside) as a file's name's element and it worked. I wonder, why Russian colon calls an exception and Japanese not. Very interesting.
Okay, I have a string
string textToShow = "this\nrocks"
which when put in label in winforms window will then show
this
rocks
Which is the result I'd like to get. Now, instead of setting the textToShow in the code, I set it in the resource file. When I tried to get the value from resource file using
Properties.Resources.ResourceManager.GetString("textToShow");
the whole string instead will be treated as verbatim, showing
this\nrocks
when put in a label in a winforms window. This is not the result i'm looking for. What's the best way to store strings with special characters in resource file then? I can do string replace for every special characters, like
string.Replace(#"\n", "\n");
but then I need to replace every special characters whenever I call method ResourceManager.GetString, which I think is not the most elegant solution. If there is some ways to make string returned from method ResourceManager.GetString not verbatim, please do tell me.
Thanks
This was already answered here: StackOverflow: How to deal with newline
Basically you have two useful options:
Use shift + enter in the resource manager text editer to add a new line.
Or use String.Format() to replace {0} with \n on read.
The .Net 4.5 framework has the unescape functionality as shown here:
using System.Text.RegularExpressions;
Regex.Unescape(Properties.Resources.ResourceManager.GetString("textToShow"));
solves your issue. Now you can use \n and \u in the resource files.
On the resource editor type "this<shift+enter>rocks" as the resource value.
I want to add double quotes for a sting . I know by using /" we can add double quotes . My string is
string scrip = "$(function () {$(\"[src='" + names[i, 0] + "']\"" + ").pinit();});";
When i do this on the browser i am getting " instead of " quotes . How can i overcome with the problem ?
If your browser has displayed a """ instead of a " character, than there are only a few causes possible. The character should have been emitted to the browser as either itself, or as a HTML entity of ". Please note the semicolor at the end. If a browser sees such 'code', it presents a quote. This is to allow writing the HTML easier, when its attribtues need to contain special characters, compare:
<div attribute="blahblahblah" />
if you want to put a " into the blahs, it'd terminate the attribute's notation, and the HTML code would break. So, adding a single " character should look like:
<div attribute="blah"e;blahblah" />
Now, if you miss the semicolon, the browser will display blah"blahblah instead of blah"blahblah.
I've just noted that your code is actually glueing up the JavaScript code. In JavaScript, the semicolon is an expression delimiter, so probably there is actually a " in the emitted HTML and it is just improperly presented in the error message... Or maybe you have forgotten to open/close some quotes in the javascript, and the semicolon is actually treated as expression terminator?
Be also sure to check why the JavaScript code undergoes html-entity translation. Usually, blocks are not reparsed. Are you setting that JavaScript code as a HTML element attribute? like OnClick or OnSend? Then stop doing it now. Create a javascript-function with this code and call that function from the click/send instead.. It is not worth to encode long expressions in the JS into an attribute! Just a waste of time and nerves.
If all else fails and if the JavaScript is emitted correctly, then look for any text-correcting or text-highlighting or text-formatting modules you have on your site. Quite probable that one of them is mis-reading the html entities and removed the semicolon, or the opposite - that they add them were they are not needed. The ASP.Net itself in general does its job right, and it translates the entites correctly wherever they are needed, so I'd look at the other libraries first.
You can use something like this:
String str=#"hello,,?!"
This should escape all characters
Or
String TestString = "This is a <Test String>.";
String EncodedString = Server.HtmlEncode(TestString);
Here's the manual: http://msdn.microsoft.com/en-us/library/w3te6wfz.aspx
What else are you doing with the string?
Seems that somewhere after that the string gets encoded. You can could use HttpUtility.HtmlDecode(str); but first you'll have to figure out where your string gets encoded in the first place.
Keep in mind that if you use <%: %> in aspx or #yourvarin Razor it will get encoded automatically. You'll have to use #Html.Raw(yourvar) to suppress that.
I have some query text that is being encoded with JavaScript, but I've encountered a use case where I might have to encode the same text on the server side, and the encoding that's happening is not the same. I need it to be the same. Here's an example.
I enter "I like food" into the search box and hit the search button. JavaScript encodes this as %22I%20like%20food%22
Let's say I get the same value as a string on a request object on the server side. It will look like this: "\"I like food\""
When I use HttpUtility.UrlEncode(value), the result is "%22I+like+food%22". If I use HttpUtility.UrlPathEncode(value), the result is "\"I%20like%20food\""
So UrlEncode is encoding my quotes but is using the + character for spaces. UrlPathEncode is encoding my spaces but is not encoding my escaped quotes.
I really need it to do both, otherwise the Search code completely borks on me (and I have no control over the search code).
Tips?
UrlPathEncode doesn't escape " because they don't need to be escaped in path components.
Uri.EscapeDataString should do what you want.
There are a few options available to you, the fastest might be to use UrlEncode then do a string.replace to swap the + characters with %20.
Something like
HttpUtility.UrlEncode(input).Replace("+", "%20");
WebUtility.UrlEncode(str)
Will encode all characters that need encoded using the %XX format, including space.
