可以正常执行
新建一个InfoHelper.cs类

public string GetHeroInfo()
{
item = new HttpItem
{
Cookie = cookie,
URL = (ServerURL + "/user/personal.ql"),
Accept = "text/html, application/xhtml+xml, */*",
UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)",
};
HttpResult result = http.GetHtml(item);
string html = result.Html;
//richTextBox1.AppendText(html + "\r\n\r\n");
html = Compress(html);
//richTextBox1.AppendText(html + "\r\n\r\n");
Match HeroShuLiang = Regex.Match(html, "(?<=英雄数量：</td><td class="n">).*?(?=<)", RegexOptions.IgnoreCase | RegexOptions.Singleline);
//richTextBox1.AppendText(HeroShuLiang + "\r\n\r\n");
item.URL = (ServerURL + HerolistURL);
result = http.GetHtml(item);
html = result.Html;
//html = Compress(html);
//截取英雄列表html
Match txtHerolist = Regex.Match(html, "(?<=英雄列表 -->).*?(?=英雄信息)", RegexOptions.IgnoreCase | RegexOptions.Singleline);
//richTextBox1.AppendText(txtHerolist + "\r\n\r\n");
string _txtHerolist = txtHerolist.Value.ToString();
//richTextBox1.AppendText(_txtHerolist + "\r\n\r\n");
Regex re = new Regex("<a.*?heroId=(.+?)"><img.*?>LV.(.+?)</span.*?h_name.oit_.">(.+?)<", RegexOptions.IgnoreCase | RegexOptions.Singleline);
MatchCollection mc = re.Matches(_txtHerolist);
//richTextBox1.AppendText(mc + "\r\n\r\n");
List<string> idlist = new List<string>();//创建list
List<string> lvlist = new List<string>();
List<string> namelist = new List<string>();
foreach (Match ma in mc)
{
idlist.Add(ma.Groups[1].Value.ToString());//捕获数据加入list
lvlist.Add(ma.Groups[2].Value.ToString());
namelist.Add(ma.Groups[3].Value.ToString());
}
HeroInfoTable = new DataTable("HeroInfo");//加入英雄信息datatable
string str = "";
HeroInfoTable.Columns.Add("ID", str.GetType());
HeroInfoTable.Columns.Add("等级", str.GetType());
HeroInfoTable.Columns.Add("名字", str.GetType());
string[] Chtml = new string[idlist.Count];
List<string> tmplist = new List<string>();
for (int i = 0; i < idlist.Count; i++)
{
tmplist.Clear();
tmplist.Add(idlist[i]);
tmplist.Add(lvlist[i]);
tmplist.Add(namelist[i]);
HeroInfoTable.Rows.Add(tmplist.ToArray());
}
return "获取英雄信息成功！";
}

复制代码

Form1改成

private void button2_Click(object sender, EventArgs e)
{
InfoHelper _InfoHelper = new InfoHelper();
comboBox1.Items.Clear();
for (int i = 0; i < _InfoHelper.HeroInfoTable.Rows.Count; i++)
{
string its = _InfoHelper.HeroInfoTable.Rows[i][2].ToString() + "-" + _InfoHelper.HeroInfoTable.Rows[i][1].ToString();
comboBox1.Items.Add(its);
}
}

复制代码

报发生了未经处理的异常
未将对象引用设置到对象实例。
这是哪里出错了？

不能执行是什么问题，比如运行不正确，还是报什么错，这不能执行叫人难以理解

刚才发的有问题重新编辑了一下！麻烦指导一下

调试一看就知道了，
HeroInfoTable应该是这样没有数据
调试的方法参考http://www.sufeinet.com/forum.ph ... hlight=%B5%F7%CA%D4

问题已解决
原来少了一行_InfoHelper.GetHeroInfo();

private void button2_Click(object sender, EventArgs e)
{
_InfoHelper.GetHeroInfo();
comboBox1.Items.Clear();
for (int i = 0; i < _InfoHelper.HeroInfoTable.Rows.Count; i++)
{
string its = _InfoHelper.HeroInfoTable.Rows[i][2].ToString() + "-" + _InfoHelper.HeroInfoTable.Rows[i][1].ToString();
comboBox1.Items.Add(its);
}
}

复制代码

这样就行了！
