How to have a verbatim string literal inside a verbatim string literal?

Question

如何在C＃中存储类似以下字符串的内容：

string mystring = @"CMD.AddParameters("@Pkey", SqlDbType.Int, Pkey.ToString());";

Answer 1

string mystring = "CMD.AddParameters(\"@Pkey\", SqlDbType.Int, Pkey.ToString());";

要么

string mystring = @"CMD.AddParameters(""@Pkey"", SqlDbType.Int, Pkey.ToString());";

Answer 2

• escape using the backslash:
  "CMD.AddParameters(\\"@Pkey\\", SqlDbType.Int, Pkey.ToString());"
• use unicode literals:
  "CMD.AddParameters("@Pkey", SqlDbType.Int, Pkey.ToString());"

fwiw, here is a link to msdn on C# verbatim strings .
