在C＃中将双引号作为字符串传递的问题

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

如果您使用转义符，则不应使用双“ //” ..尝试使用单“ /” ..它将是有效的..或在双引号之前仅使用@。

Answer 2

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.

我希望使用带转义双引号的逐字字符串：

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