How to include quotes in a string
(8 answers)
Closed 3 months ago.
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'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 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

I'm trying to print \"Hey\" in the Console But when I run it It just print the "Hey" without \ and when i put another \ in the beginning and \ in end it says theres an Error
You have to escape the " as well as the \. Both should be escaped with a backslash itself. Your final result should look something like:
Console.WriteLine("\\\"Hey\\\"");

Unicode character range not being consumed by Regex
(3 answers)
Closed 3 years ago.
I'm using this statement to remove emoticons from a string:
text = Regex.Replace(text, #"[^\u1F600-\u1F64F]+", ""); //Emoticons
Based on the official Unicode page chart, https://www.unicode.org/charts/PDF/U1F600.pdf.
But this replace statement not only remove emoticons also removes another characters like "." or "-".
Why is that?

How do I restrict special characters and character in a Textbox?
I'm using this code but I am not restricting special characters and character
code :-
if (!Regex.IsMatch(((Windows.UI.Xaml.Controls.TextBox)sender).Text, #"^\\d*\\.?\\d*$"))
{
// Write Code
}
if you're using # in front of string, you don't have to escape characters. So, remove all those extra backslash chars and your regex should work. Like this:
if (!Regex.IsMatch(((Windows.UI.Xaml.Controls.TextBox)sender).Text, #"^\d*\.?\d*$"))
EDIT:
use sites like this to test your regex.
