简单的C＃正则表达式示例

Question

I am searching through a database schema text file where all stored procedures, functions, triggers and views are delimited by ";;". I am splitting the contents on the ";;" delimiter and then for each piece, looking for "CREATE PROCEDURE", "CREATE FUNCTION", "CREATE TRIGGER" or "CREATE VIEW". However, this search criteria could not be as perfect as I just listed. For example, "CREATE PROCEDURE" could be: "create PROCEDURE", "create procedure", "CREATE PROCEDURE", etc.

This looks like a pretty simple regex pattern to check for but I am new to regex and struggling a bit. Any help would be appreciated.

Answer 1

var regex = new Regex(@"\bcreate\s+(procedure|function|view|trigger)" + 
                      @"\s+(?<ObjectName>[a-z_][a-z0-9_]+)\b", 
                      RegexOptions.IgnoreCase);
