Description:
For example if you insert into a table using ExecuteNonQuery:

INSERT INTO `table_name` (`varchar_column_name`) VALUES ( '\\') -- escaped \

There is an exception:
System.ArgumentOutOfRangeException: Index and length must refer to a location within the
string. Parameter name: length

I found a bug in the code ReadQuotedToken, there does not need a variable "escaped"
(which also was not necessary and in the old code tokenizer)

Sorry for English, this electronic translator.

How to repeat:
Try to insert \ (backslash) in varchar column

Suggested fix:
Remove variable "escaped" in the method "MySqlTokenizer.ReadQuotedToken"

is likely
to be the same. Because of this, we hope you add your comments to the original bug

Thank you for your interest in MySQL.
