c# - Escape double quotes in string

Double quotes can be escaped like this:

string test = @"He said to me, ""Hello World"". How are you?";

But this involves adding character " to the string. Is there a C# function or other method to escape double quotes so that no changing in string is required?

Answer

No.

Either use verbatim string literals as you have, or escape the " using backslash.

string test = "He said to me, \"Hello World\" . How are you?";

The string has not changed in either case - there is a single escaped " in it. This is just a way to tell C# that the character is part of the string and not a string terminator.
