I'm struggling with escape characters in C#.
I'm saving a varchar field in a SQL Server database with a quote that needs to be escaped. So, an example could be something like that: (\"value\")
When my frontend application consume this value from API I get the value with a single escape character as i have in the DB.
The problem come up when consuming this API from C# code. For some reason this single character (\) is replaced for three of them (\\\).
After debugging the code I found that when I retrieve the data I get this:
debugging the value
When I click to check the value it seems OK:
Value into Text Visualizer
My question is why theese two extra backslashes are added and how can I get rid of them in order to get only one => (\").
Hope anyone can help me :)
Thanks!
You value should be correct. The debugger window escape the “/“, therefore it appears like escape(backslash)escape(quote).
(//)(/“)

I want to write something with Console.WriteLine, but the text contains "".
Example:
Console.WriteLine("example: "this is an example" example");
How to avoid this problem?
I tried '' and other symbols, but it didn't work
Use the backslash character to mark the quotations, as shown:
Console.WriteLine("example: \"this is an example\" example");
This is used in languages to mark special characters, in this case marking the quotation so that it doesn't end the string prematurely.

I need to pass the folder path to the Python interface but spaces in the path make it complicated.
Example :
Defect.py C:\TestImage\Images works fine.
However, if there is a space in the path as below,
`Defect.py C:\**Test Image**\Images`
causes an error due to two separate parameters.
If I could pass it as :
Defect.py "C:\**Test Image**\Images" should work
So I am currently trying to use string.Format("{0}") to format this string with double quotations but does not work.
Please let me know how I could format the statement using string.Format. I need to use string.Format since there are multiple other parameters.
Try this:
string.Format("Defect.py \"C:\\{0}\\Images\"", "Test Image");
Bear in mind that the whole trick is to escape the character using the \" backslash escape character. The rest of it was just to show how to use the string.Format

What's the difference between double quotes and single quote in C#?

Hi does somebody know what is the difference between "" and '' in c#.
I've tried searching the web but I've found nothing.
Thx for the answers.
"Y" is a string, and 'Y' is a char.
Single quotes encode a single character (data type char), while double quotes encode a string of multiple characters. The difference is similar to the difference between a single integer and an array of integers.

Backslash Escape Sequence displaying both backslashes
(1 answer)
Closed 7 years ago.
I have a string like,
var log = "C:\\folder\\folder2\\this.txt";
For some reason this does not escaped the backslash, it still shows the backslashes in the string as below:
C:\\folder\\folder2\\this.txt
How do I properly escaped the \ character to allow writing to a file at such a location?
You are looking at it in the debugger, There is no double back slash in actual string. The debugger shows it like that.
Do:
Console.WriteLine(log);
and it will display the string without double back slashes in the console.
You are bound to see double backslashes if you're in the IDE, but they won't be there when you actually use the string.
As a bonus, you can rewrite your string as var log = #"C:\folder\folder2\this.txt";

i have a semicolon separates string, that contains values of every type. string and date values are in quotations.
Now i have an evil string, where an inner string contains s semicolon, that i need to remove (replace by nothing).
eg:
"Value1";0;"Value2";4711;"Evil; Value";"2015-09-03"
in C#:
string value = "\"Value1\";0;\"Value2\";4711;\"Evil; Value\";\"2015-09-03\""
So how to replace all semicolons, that are in quotations? can anybody help?
Regex is awful at handling delimited strings. It can do it, but it's not often as good of a choice as it first appears. This is one of several reasons why.
Instead, you should use a dedicated delimited string parser. There are (at least) three built into the .Net framework. The TextFieldParser type is one of those, and it will handle this correctly.
You should try this i.e to match only those semicolons which is not preceded by : :
(?<=[^"]);
