DropDownList控件数据绑定

DropDownList控件的绑定Dictionary<int, string>

DropDownList控件的绑定DataTable

1、绑定Dictionary<int, string>

1Dictionary<int, string> temp = DBConfig.GetDataAdmin(fileName);

2this.ddlDicItem.DataSource = temp;

3this.ddlDicItem.DataTextField = "Value";

4this.ddlDicItem.DataValueField = "Key";

5this.ddlDicItem.DataBind();
2、绑定DataTable

1this.ddlAllDics.DataSource = DBConfig.Dictionary;

2this.ddlAllDics.DataTextField = DBConfig.Dictionary.Columns[1].ToString();

3this.ddlAllDics.DataValueField = DBConfig.Dictionary.Columns[0].ToString();

4this.ddlAllDics.DataBind();
特别是绑定Dictionary<int, string> ，开发中写成了

this.ddlDicItem.DataTextField = temp.Values.ToString();
这个怎么会不出错呢？失败...
