Is there a way to alphabetically a list of members by name or last name (custom property) in razor?

Here's how I'm getting a list of all members.

<ul class="memberList">
        @foreach (var member in allMembers)
        {

            var currentMember  = new Member(Convert.ToInt32(@member.Id));
            <li class="clearfix">
        <figure class="headshot small">
           @{
                    if (@currentMember.getProperty("memberPhoto").Value != String.Empty) {
                        <img src="@currentMember.getProperty("memberPhoto").Value" alt="@currentMember.Text" width="140" />
                    }
                    
                    else {
                        <img src="@(currentMember.Email.GetGravatarUrl(250, string.Empty))&d=http%3A%2F%2Fccup.blackswaninteractive.com%2Fimages%2Fheadshot-placeholder.jpg" alt="@currentMember.Text" width="140" />
                    }
                }
        </figure>
        <div class="profile small">
           @if (Umbraco.MemberIsLoggedOn()){
            <h2><a href="/profiles/[email protected]">@member.Text @currentMember.getProperty("lastName").Value</a></h2>
            }
            else {
            <h2>@member.Text</h2>
             <p>Please <a href="/register/">sign up</a> or <a href="/login/">login</a> to see full profiles.</p>
        }
           
        </div>
    </li>
        }
    </ul>
