Answer 4

我是这样用的

        foreach (Object m in System.Text.RegularExpressions.Regex.Matches(@"fafafafdsf\<\%=xyz\%\>attrwttewt\<\%=zy\%\>fa34rtt\<\%=tt\%\>",@"(?<=<%=).+?(?=\%\>)"))
        {
            Response.Write(m.ToString());
        }

Answer 5

我是这样用的

        foreach (Object m in System.Text.RegularExpressions.Regex.Matches(@"fafafafdsf\<\%=xyz\%\>attrwttewt\<\%=zy\%\>fa34rtt\<\%=tt\%\>",@"(?<=<%=).+?(?=\%\>)"))
        {
            Response.Write(m.ToString());
        }

//饺子给出的正则是没有问题的 你自己使用的问题

foreach (Match m in System.Text.RegularExpressions.Regex.Matches(@"fafafafdsf<%=xyz%>attrwttewt<%=zy%>fa34rtt<%=tt%>",@"(?<=<%=).+?(?=%>)"))
		{
			<span style="font-size:11px; white-space:normal"> Response.Write</span>(m.Value);
		}
