为什么c#向Oracle插入数据时提示：Ora-00911无效字符

Answer 1

ORA-00911: invalid character
Cause: identifiers may not start with any ASCII character other than letters and numbers. $#_ are also allowed after the first character. Identifiers enclosed by doublequotes may contain any character other than a doublequote. Alternative quotes (q'#...#') cannot use spaces, tabs, or carriage returns as delimiters. For all other contexts, consult the SQL Language Reference Manual.
Action: none
检查你的数据，字符串数据的双引号、数值型数据的非数字等
