做了一个项目，其中用了很多枚举。在页面上单独写下拉列表，这样觉得很不统一。所以google了一下枚举绑定下拉列表的方法，发现都不是通用的方法。于是修改了网上的代码写成了一个通用的枚举绑定列表方法。下面贴代码。

 1    /**//// <summary>
 2    /// 用枚举绑定列表
 3    /// 作者：阿松
 4    /// </summary>
 5   /// <param name="col">控件名</param>
 6   /// <param name="eumeName">枚举名</param>
 7    public static void BindData(Control col, string enumName)
 8    {
 9        System.Reflection.Assembly asm = Assembly.Load("App_Code"); //枚举是在App_Code里      
        Type type = asm.GetType(enumName);
11        FieldInfo[] fields = type.GetFields();
12        int count = fields.Length;
13
14        if (col is DropDownList)
15        {
16            DropDownList ddl = (DropDownList)col;
17            ddl.Items.Clear();
18            for (int i = 1; i < count; i++)
19            {
20                FieldInfo field = fields[i];
21                ListItem item = new ListItem(field.Name);
22                ddl.Items.Add(item);
23            }
        }
        else if (col is HtmlSelect)
26        {
27            HtmlSelect ddl = (HtmlSelect)col;
28            ddl.Items.Clear();
29            for (int i = 1; i < count; i++)
30            {
31                FieldInfo field = fields[i];
32                ListItem item = new ListItem(field.Name);
33                ddl.Items.Add(item);
34            }
        }
        else if (col is CheckBoxList)
37        {
38            CheckBoxList ddl = (CheckBoxList)col;
39            ddl.Items.Clear();
40            for (int i = 1; i < count; i++)
41            {
42                FieldInfo field = fields[i];
43                ListItem item = new ListItem(field.Name);
44                ddl.Items.Add(item);
45            }
        }
        else if (col is RadioButtonList)
48        {
49            RadioButtonList ddl = (RadioButtonList)col;
50            ddl.Items.Clear();
51            for (int i = 1; i < count; i++)
52            {
53                FieldInfo field = fields[i];
54                ListItem item = new ListItem(field.Name);
55                ddl.Items.Add(item);
56            }
        }
        else if (col is ListBox)
59        {
60            ListBox ddl = (ListBox)col;
61            ddl.Items.Clear();
62            for (int i = 1; i < count; i++)
63            {
64                FieldInfo field = fields[i];
65                ListItem item = new ListItem(field.Name);
66                ddl.Items.Add(item);
67            }
        }
    }

 

如里枚举是写在项目里面的话 上面 System.Reflection.Assembly asm = Assembly.Load("App_Code");改写成 System.Reflection.Assembly asm = Assembly.Load("成程集");

调用时 为  PublicFun.BindData("控件ID"，"命名空间.枚举");

顺便贴一下其它的类型的数据的绑定方法  如下....
