makes v something called a verbatim string. What is this and what is a common scenario to use it?

推荐答案

这意味着不需要转义特殊字符，因为您已告知编译器期望特殊字符并忽略它们。常见的用例是指定连接字符串：

It means that special chars don't need to be escaped, since you informed the compiler to expect special characters, and to ignore them. A common use case might be to specify a connection string:

string sqlServer = @"SERVER01\SQL"; 

这是完全有效的，与通常使用反斜杠被认为是转义字符的情况相反。

This is perfectly valid, as opposed to in normal use where the backslash would be considered an escape character.
