Question

我想遍历每一行，每一列和所有单元格。然后用列表填充每一列。我有一个受雇对象列表，每个受雇者都有一个ID名称和一个城市。我想用受雇者列表填充gridview。第一列应该是所有雇员的身份证，第二列应该是每个雇员的名字，第三列应该是每个雇员的城市。我无法使之工作，将不胜感激。

这是我前端的样子。

       <asp:GridView ID="GridView1" AllowPaging="true"  ShowFooter="true" PageSize="5" OnPageIndexChanging="GridView1_PageIndexChanging" OnRowEditing="GridView1_RowEditing"
            runat="server"  CellPadding="3"  GridLines="None" CssClass="mGrid" PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt"

         </asp:TemplateField>
                </Columns>
       </asp:GridView>

这是我后端的样子。

  protected List<Emp> GetEmpList()
        {
            List<Emp> lEmp = new List<Emp>();
            Emp oemp = new Emp(1234, "Upendra", "Noida");
            lEmp.Add(oemp);
            oemp = new Emp(1234, "Upendra", "Noida");
            lEmp.Add(oemp);
            oemp = new Emp(1374, "Vishal", "Noida");
            lEmp.Add(oemp);
            oemp = new Emp(1934, "Rahul", "Noida");
            lEmp.Add(oemp);

            return lEmp;
        }

        protected void BindGridList()
        {    
            for (int i = 0; i < GridView1.Columns.Count - 1; i++)
            {
                foreach (GridViewRow row in GridView1.Rows)
                {
                    row.Cells[i].Text = GetEmpList()[i].ID.ToString();
                }    
            }
        }


    }
    public class Emp
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public string City { get; set; }
        public Emp(int id, string name, string city)
        {
            this.ID = id;
            this.Name = name;
            this.City = city;
        }
  }

我找到了一个解决方案，但是在下一页上不起作用。

    protected void BindGridList()
    {
        for (int i = 0; i < GridView1.Columns.Count - 1; i++)
        {
               foreach (GridViewRow row in GridView1.Rows)
                {
                if (i == 0)
                {
                    row.Cells[i].Text = GetEmpList()[row.RowIndex].ID.ToString();
                }
                else if (i == 1)
                {
                    row.Cells[i].Text = GetEmpList()[row.RowIndex].Name.ToString();
                }
                //....
             }
        }
}
