使用 LINQ 获取数据并在网格视图中显示结果

如何在 C# 和 Asp.net 中使用 Linq 从数组中获取所有模块，如下所示，其中学生名字。这可能是很容易做到的事情，但未能掌握窍门。请帮忙。谢谢。

ArrayList arrList = new ArrayList();  //new array list for students
        arrList.Add(
            new Student
            {
                FirstName = "Svetlana",
                LastName = "Omelchenko",
                Password = "hh",
                modules = new string[] { "001", "002", "003", "004" }
            });
        arrList.Add(
            new Student
            {
                FirstName = "Claire",
                LastName = "O’Donnell",
                modules = new string[] { "001", "002", "003", "004" }
            });
        arrList.Add(
            new Student
            {
                FirstName = "Sven",
                LastName = "Mortensen",
                modules = new string[] { "001", "002", "003", "004" }
            });
        arrList.Add(
            new Student
            {
                FirstName = "Cesar",
                LastName = "Garcia",
                modules = new string[] { "HH", "KK", "LL", "OO" }
            });





            var query = from Student student in arrList
                    where student.FirstName == "Cesar"
                    select  query;

           GridView1.DataSource = query;


           GridView1.DataBind();

我想将结果放入 Asp.net 中的网格表中。请帮忙！！

您在查询末尾缺少 ToList。

yourGridView.DataSource = (from Student s in arrList
                    where s.FirstName == "Cesar"
                    select s).ToList();

然后将其绑定到您的网格视图。
