使用DataSource绑定一维数组时，DataTextField只需绑定空字符串

方法定义：

public static void InitDropDownList(DropDownList ddl, bool isAddTopItem, DropDownList ddlSub, object ddlDataSource, string ddlTextField, string ddlValueField)
{
    ddl.DataSource = ddlDataSource;
    ddl.DataTextField = ddlTextField;
    ddl.DataValueField = ddlValueField;
    ddl.DataBind();
    if (isAddTopItem)
        ddl.Items.Insert(0, new ListItem("--All--", "0"));
    if (ddlSub != null)
        ddlSub.Items.Insert(0, new ListItem("--All--", "0"));
}

 

使用方式：

XXClass.InitDropDownList(ddlAvailableFieldEnter, false, null, new string[]{"field1","field2","field3"}, "", "");
