关于自定义控件属性？？急！！！

[alan817]

public class UserFieldControl : Control, INamingContainer
{
。。。。。。。。。。。。。。。。。。。。。。

public string FieldName
        {
            get
            {
                object obj = this.ViewState["FieldName"]; 
HttpContext.Current.Response.Write(obj == null); 
HttpContext.Current.Response.Write("<br />");              
                if (obj != null)
                {
                    return (string)obj;
                }
                return string.Empty;
            }
            set
            {
                this.ViewState["FieldName"] = value;     
HttpContext.Current.Response.Write(this.ViewState["FieldName"] );   
HttpContext.Current.Response.Write("<br />");        
            }
        }

public ArrayList FieldPropertys
        {
            get
            {
                object obj = this.ViewState["FieldPropertys"];
HttpContext.Current.Response.Write(obj == null);   
HttpContext.Current.Response.Write("<br />");
                if (obj != null)
                {
                    return (ArrayList)obj;
                }
                else
                {
                    ArrayList property = new ArrayList();
                    for (int i = 0; i < 10; i++)
                    {
                        property.Add(string.Empty);
                    }
                    return property;
                }
            }
            set
            {
                this.ViewState["FieldPropertys"] = value;
HttpContext.Current.Response.Write(this.ViewState["FieldPropertys"] ); 
HttpContext.Current.Response.Write("<br />");  
            }
        }

}

。。。。。。。。。。。。。。

在页面中设置好控件属性后输出：

test //fieldName的值
True // fieldname中判断 obj == null
False // FieldPropertys 中判断 obj == null
System.Collections.ArrayList //FieldPropertys 的值

为什么FieldPropertys 会先get再set？？其他类型的属性都是先 set 再 get
老取不到FieldPropertys 的值

放了这么久没人知道，自己搞定了，Value属性放到最后
