正则抓取网页input里面的值

[chenlunmy006]

想写调正则匹配下面html里面 input的值

<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKLTE5NDA1MDQ0Ng9kFgICAQ9kFgYCBQ8WAh4HVmlzaWJsZWhkAgcPFgIfAGhkAgkPFgIfAGhkZA==" />
</div>

请问c#正则源码应该怎么写

string text = @"<div class=""aspNetHidden"">
<input type=""hidden"" name=""__VIEWSTATE"" id=""__VIEWSTATE"" value=""/wEPDwUKLTE5NDA1MDQ0Ng9kFgICAQ9kFgYCBQ8WAh4HVmlzaWJsZWhkAgcPFgIfAGhkAgkPFgIfAGhkZA=="" />
</div>";
            string value = Regex.Match(text, @"(?i)<div[^>]*?class=(['""]?)aspNetHidden\1[^>]*?>\s*?<input[^>]*?value=(['""]?)(?<value>[^'""]*?)\2[^>]*?>\s*?</div>").Groups["value"].Value;
            ///wEPDwUKLTE5NDA1MDQ0Ng9kFgICAQ9kFgYCBQ8WAh4HVmlzaWJsZWhkAgcPFgIfAGhkAgkPFgIfAGhkZA==
