使用正则表达式C＃从字符串中查找和替换/删除两个单词

Question

I'm trying to read scripts from various .sql files into a string and execute them in SQL server using c#. I want to remove the terms USE, GO etc. I succeeded removing one word at a time but cannot find the pattern to search for two or more words at the same time.

so far,

string pattern =  @"\bUSE*\b";
string script = Regex.Replace(script, pattern, "");

How to add other search terms to the pattern? i tried msdn docs and previous questions but cannot find what i need. Any help is greatly appreciated.

Answer 1

您可以在关键字中使用管道。

string pattern =  @"\b(USE|GO|MORE|FEW_MORE|AND_SO_ON)\b";

Answer 2

I'm a little rusty, but have you tried

string pattern = @"\bUSE*\b|\bGO*\b"

??
