asp.net 用户控件直接取值

如：有用户控件header、affiche，

在affiche中获取header的值（前提这些值必须public）

在affiche.cs中加入

多个属性值：

Page p = this.Parent.Page; UserControl uc = p.FindControl("header1") as UserControl;
Type pageType = uc.GetType();
FieldInfo[] myFields = pageType.GetFields(BindingFlags.Public | BindingFlags.Instance);

for (int i = 0; i < myFields.Length; i++)
{
Response.Write(string.Format("The value of {0} is: {1}", myFields[i].Name, myFields[i].GetValue(uc)));
}

单个属性值：

Page p = this.Parent.Page;
UserControl uc = p.FindControl("header1") as UserControl;
Type pageType = uc.GetType();
FieldInfo field = pageType.GetField("cityId", BindingFlags.Public | BindingFlags.Instance);
if (field != null)
{
CityId = field.GetValue(uc).ToString();
}
