c# 寻找字符串中指定 字段 替换
string a1={ <td style="TEXT-ALIGN: center; HEIGHT: 40px; BORDER-TOP: red 1px solid; BORDER-RIGHT: red 1px solid"><IMG style="CURSOR: hand" id=0.1869366964525968 onclick=openyz(0.1869366964525968,201211189789) name=0.1869366964525968 alt="" src="/images/123.gif"> </td>
<td style="TEXT-ALIGN: center; HEIGHT: 40px; BORDER-TOP: red 1px solid; BORDER-RIGHT: red 1px solid"><IMG style="CURSOR: hand" id=0.5159706003032625 onclick=openyz(0.5159706003032625,201211187808) name=0.5159706003032625 alt="" src="/images/123.gif"> </td>
<td style="TEXT-ALIGN: center; HEIGHT: 40px; BORDER-TOP: red 1px solid; BORDER-RIGHT: red 1px solid"><IMG style="CURSOR: hand" id=0.1869366964525968 onclick=openyz(0.1869366964525968,201211189791) name=0.1869366964525238 alt="" src="/images/123.gif"> </td> }
string a2= "201211187808";
如上两个字符串 在 a1 中 查找 a2 如果相等 则将 后面的 src="/images/123.gif" 替换为 src="/images/1234.gif"
各位大虾 请赐教
