Issue with passing double-quotes as a string in c#

Question

I need to pass the below path as URI.

 https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d "code=DBvmp1o9"

I used the below solutions to implement escape charecter for the double-quotes which resulted in Internal Server error.

Solution 1: string URI = "https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d \"code=" + accessCode + "\"";

Solution 2 (Verbatim string literal): string URI = @"https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d ""code=" + accessCode + ""; Any help is greatly appreciated.

Answer 1

I would prefer a verbatim string with escaped double-quote:

string URI = @"https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d \""code=accessCode\""";

Answer 2

if you put escape character you should not use double "//" .. try using single "/" .. it will be work .. or use simply @ before the double quotes.

Answer 3

I tried the code you provide, and the result is: https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d "code=DBvmp1o9

Lacking double-quotes at the end. I bet that because the last double-quotes wasnt escaped by verbatim. +"" considered empty string instead of double-quotes. Your solution 2 should be:

string URI = @"https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d ""code=" + accessCode + @"""";

Or

string URI = string.Format(@"https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d ""code={0}""", accessCode);

Given the accessCode hardcoded to "DBvmp1o9", the output of both code as i tested should be: https://api.mytrade.com/oauth/accesstoken?grant_type=auth_code -d "code=DBvmp1o9"

This is my best shot. If you get the same output but still getting the Internal Server Error, then you can go with implementing using uri-escape as you said.
