C#正则表达式获取下拉菜单(select)的相关属性值

给几个在C#中，使用正则表达式取页面下拉菜单(select)中的值示例:

//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>");

一下是一段完整的代码和方法，取html中一个下拉菜单 select name 等于”Status”的中值，添加到DropDownList中:

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

/// </summary>

/// <param name="selected"></param>

/// <param name="cmb"></param>

void getSelectOptions(MatchCollection selected, ComboBox cmb)

{

    if (selected.Count < 1)

        return;

    txtValues.Text = "";

    txtValues.Text = selected[0].Value.Replace("</option>", Environment.NewLine);

    string tmpTxt = "";

    foreach (string s in txtValues.Lines)

    {

        if (s == "")

            continue;

        string a = "";

        a = s.Replace("\"", "").Replace("<option value=\"", "");

        int x = a.LastIndexOf(">");

        tmpTxt += a.Substring(x + 1) + Environment.NewLine;

    }

    txtValues.Text = tmpTxt.Trim();

    cmb.Items.Clear();

    cmb.Items.AddRange(txtValues.Lines);

    cmb.SelectedIndex = 0;

    cmb.Size = cmb.PreferredSize;

}
