c# - StringBuilder.ToString() is adding '' characters in the beginning and ending of the string

Question

StringBuilder.ToString() is adding '' characters in the beginning and ending of the string.

Why is this?

Before calling .ToString() the string doesn't have the '' character.

Answer 1

Are you thinking of these backslashes here?

If so, you are misreading the output: The backslashes are not actually in the string. They are only displayed here to make the representation valid according to C# syntax. If you were to output the string using Console.WriteLine, for example, it would not have backslashes.

To be fair, it is inconsistent. The debug view for the StringBuilder doesn’t have the backslashes, but the one for strings does.
