如何通过用户displayname开头的CSOM从sharepoint组中检索用户列表？

using Microsoft.SharePoint.Client;

string siteUrl = "https://your-sharepoint-site-url";
string groupName = "Your Group Name";
string displayNamePrefix = "Your Display Name Prefix";

using (ClientContext context = new ClientContext(siteUrl))
{
    GroupCollection groups = context.Web.SiteGroups;
    context.Load(groups);
    context.ExecuteQuery();

    Group targetGroup = groups.GetByName(groupName);
    context.Load(targetGroup.Users);
    context.ExecuteQuery();

    List<User> users = new List<User>();

    foreach (User user in targetGroup.Users)
    {
        if (user.LoginName.StartsWith(displayNamePrefix))
        {
            users.Add(user);
        }
    }

    // 处理符合条件的用户列表
    foreach (User user in users)
    {
        // 进行相关操作，如输出用户信息等
        Console.WriteLine("User: " + user.Title);
    }
}
