正则表达式提取string 中的表名

简单版本：

Regex reg = new Regex(@"(?i)\bfrom\b(?![^\[\]]*\])\s+(\[[^\[\]]+\]|\S+)");
MatchCollection mc = reg.Matches(yourStr);
foreach (Match m in mc)
{
    richTextBox2.Text += m.Groups[1].Value + "\n";
}

支持过滤join，left join等复杂联表过滤表名

Regex reg = new Regex(@"(?in)\b(from|(left|right|INNER)\s+join)\b(?![^\[\]]*\])\s+(?<table>\[[^\[\]]+\]|\S+)");
MatchCollection mc = reg.Matches(yourStr);
foreach (Match m in mc)
{
    richTextBox2.Text += m.Groups["table"].Value + "\n";
}
