My goal is to pass a JSON string from Javascript to a C# .exe as a command line argument using node.js child-process. The JSON I am working with looks like this:
string jsonString = '{"name":"Tim"}'
The challenge lies in preserving the double quotation marks when passing it as a C# argument for proper parsing. To achieve this, I need to escape the double quotes in the JSON before passing it to C#, resulting in a format like this:
string jsonStringEscaped = '{\"name\":\"Tim\"}'
This approach ensures consistency in the object structure between the two languages, which is crucial for my project.
To handle this conversion, I tried using the JavaScript .replace() method along with a simple RegEx pattern:
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\"")
However, the output '{\\"name\\":\\"Tim\\"}' was not ideal and did not serve my purpose effectively.
I experimented with different variations of the RegEx pattern, such as:
string jsonStringEscaped = jsonString.replace(/\"/g,"\\ \"")
\\ returns '{\\ "name\\ ":\\ "Tim\\ "}'
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\\")
\\ returns '{\\\\name\\\\:\\\\Tim\\\\}'
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\")
\\ is invalid
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\ ")
\\ returns '{\\ name\\ :\\ Tim\\ }'
Even after trying different single or double quotation mark combinations, I couldn't find a satisfactory solution.
If anyone can provide guidance on where I might be going wrong or suggest a more efficient method to achieve my desired outcome, I would greatly appreciate it.
