C#正则表达式获取下拉菜单(select)的相关属性值

//取html中全部 select 的 name
Regex reg_name = new Regex(@"(<=<select name=\"").*(=\"")");

//取html中全部<select>项的值
Regex reg_select = new Regex("(is)<select name=*.*>]*.*</select>");

//取html中一个 select name 等于"Status"的值
Regex status = new Regex(@"(is)<select name=\""status\"">]*.*</select>");

string strDoc = （你的html）;

//取html中一个下拉菜单 select name 等于"Status"的中值
Regex status = new Regex(@"(is)<select name=\""status\"">]*.*</select>");
MatchCollection mc_status = status.Matches(strDoc);
getSelectOptions(mc_status, cmbStatus);

/// <summary>
/// 取select对列表复制
