页面中的传参介质(ViewState,Session,Items),Dictionary的用法.
private List<int> QuotationIds //List<int>可以是List<string>,bool,class(类),int,string...
{
get
{
object o = ViewState["QuotationIds"]; //ViewState可以是Session,Items.
if (o == null)
{
o = new List<int>();
ViewState.Add("QuotationIds", o);
}
return (List<int>)o;
}
set
{
ViewState["QuotationIds"] = value;
}
}
2例.
private string PartWhere
{
get
{
object o = ViewState["PartWhere"];
if (o == null)
o = string.Empty;
return (string)o;
}
set
{
ViewState["PartWhere"] = value;
}
}
3例.
private int[] QuotationIDs
{
get
{
return (int[])Items["QuotationIDs"];
}
set
{
Items["QuotationIDs"] = value;
}
}
4.protected Bid CurrentBid //Bid是一个类
{
get
{
return (Bid)Session["CurrentBid"];
}
set
{
Session["CurrentBid"] = value;
}
}
5.protected Dictionary<string, string> ToolNames //<string,string>这里的类型可以自己设定,可以为<int,int>,也可以为<int,string>
{
get
{
object o = ViewState["ToolNames"];
if (o == null)
{
o = new Dictionary<string, string>();
ViewState.Add("ToolNames", o);
}
return (Dictionary<string, string>)o;
}
}
