c# - 如何遍历通用 List 并按 3 项进行分组

Question

我想遍历 MemberProfiles 的通用列表:

List<MemberProfile> jobseekers    

，并将项目分组在 <div class='group'> 中标签。每个<div class="group">应该包含 3 个这样的求职者:

<div class="group">
    <div class="jobseeker">
        ...data jobseeker
    </div>
</div>

我在通用列表上尝试了不同的方法，例如 .skip() 和 .take() 但我没有成功实现这种情况。

我的代码是这样的:

foreach (MemberProfile jobseekerProfile in Jobseekers)
{
    if (jobseekerProfile != null)
    {
        Label lblJobseeker = new Label();
        StringBuilder sbJobseeker = new StringBuilder();
        sbJobseeker.Append(string.Format("<p><strong>{0}&nbsp;{1}</strong><br />", jobseekerProfile.FirstName, jobseekerProfile.LastName));
        XPathNodeIterator preValues = library.GetPreValues(1362);
        preValues.MoveNext();
        XPathNodeIterator iterator2 = preValues.Current.SelectChildren("preValue", "");
        while (iterator2.MoveNext())
        {
            if (jobseekerProfile.JobType == iterator2.Current.GetAttribute("id", ""))
            {
                sbJobseeker.Append(string.Format("looking for a {0}<br />", iterator2.Current.Value));
            }
        }
        XPathNodeIterator iterator3 = library.GetPreValues(1363);
        iterator3.MoveNext();
        XPathNodeIterator iterator4 = iterator3.Current.SelectChildren("preValue", "");
        StringBuilder sbJobExperience = new StringBuilder();
        string[] strJobExperience = jobseekerProfile.JobExperience.Split(new char[] { ',' });
        int counter = 1;
        while (iterator4.MoveNext())
        {
            if (jobseekerProfile.JobExperience.Contains(iterator4.Current.GetAttribute("id", "")))
            {
                if (counter != strJobExperience.Count<string>())
                {
                    sbJobExperience.Append(string.Format("{0}, ", iterator4.Current.Value));
                    counter++;
                }
                else
                {
                    sbJobExperience.Append(string.Format("{0}", iterator4.Current.Value));
                }
            }
        }
        sbJobseeker.Append(string.Format("Fields of experience: {0}<br />", sbJobExperience.ToString()));
        sbJobseeker.Append(string.Format("Years of experience: {0}<br />", jobseekerProfile.YearsExperience));
        sbJobseeker.Append(string.Format("Country: {0}<br />", jobseekerProfile.Country));
        sbJobseeker.Append(string.Format("<form name='frmSelect' action='/selectjobcandidate.aspx' method='post'><input type='hidden' name='username' value='{0}' /><input type='submit' value='select candidate' /></form>", jobseekerProfile.UserName));
        lblJobseeker.Text = sbJobseeker.ToString();
        phListJobseekers.Controls.Add(lblJobseeker);
    }
}    

有人可以让我走上正确的轨道来实现这个场景吗？

Answer 1

for (var i = 0; i < Jobseekers.Count; i += 3)
{
    foreach (MemberProfile jobseekerProfile in Jobseekers.Skip(i).Take(3))
    {

    }
}

这就是你想要的吗？
