如何从 PropertyInfo 集合中, 得到集合属性的值...

btbtd 2007-05-06 07:39:51

比如我想遍历 Request 的属性,,,

下面代码是做到了...
---/-------------------------------------------------
<%@ Page Language="C#" AutoEventWireup="True" %>
<%@ import namespace="System.Reflection" %>
<script runat="server">
void Page_Load(Object s, EventArgs e)
{
EnumProperties(Request);
} // end Page_Load

void EnumProperties(Object Obj)
{
PropertyInfo[] Props = Obj.GetType().GetProperties();
for(int i=0, j=Props.Length; i<j; i++)
{
Response.Write("<li/>Props["+i+"].Name: "+Props[i].Name);
}
}
</script>

但是我想得到每个属性的对应值, 我发傻了...该怎么弄...
比如我想得到 Request.Url 的值...

是从PropertyInfo 集合中去获取, 如果是单一遍历, 这地球人都会...

:() 楼上...
上面的代码不是已经弄出来了吗, 俺还看那干吗...

public static void EnumProperties(Object Obj)
{ // shawl.qiu code
string ObjectName = Obj.ToString();
HttpContext.Current.Response.Write
(
"<h2 style='text-align:center; color:red;'>"+ObjectName+"</h2>"
);
PropertyInfo[] Props = Obj.GetType().GetProperties();
for(int i=0, j=Props.Length; i<j; i++)
{
HttpContext.Current.Response.Write
(
"<li/><span style='color:blue;font-weight:bold'>"+ObjectName+"."+Props[i].Name+"</span>: "
);
if(Props[i].CanRead)
{
try
{
object o = Props[i].GetValue(Obj, null);
if (o!= null)
{
HttpContext.Current.Response.Write(o);
}
}
catch(Exception ex)
{
HttpContext.Current.Response.Write
(
"<span style='color:red;font-weight:bold;'>"+ObjectName+"."+Props[i].ToString()+"</span>"
);
HttpContext.Current.Response.Write("<li/> Error Message: ");
HttpContext.Current.Response.Write(ex.Message);
HttpContext.Current.Response.Write("<hr/>");
} // end try
} // end if
} // end for
} // void EnumProperties

public static void EnumProperties()
{
EnumProperties("ServerVariables");
}

public static void EnumProperties(string cdti)
{
switch(cdti)
{
default:
int loop1, loop2;
NameValueCollection coll;
coll=HttpContext.Current.Request.ServerVariables;
String[] arr1 = coll.AllKeys;
string ObjectName = HttpContext.Current.Request.ServerVariables.GetType().ToString();
HttpContext.Current.Response.Write
(
"<h2 style='color:red;text-align:center'>"+
ObjectName+
"</h2>"
);
for (loop1 = 0; loop1 < arr1.Length; loop1++)
{
HttpContext.Current.Response.Write
(
"<li/><span style='color:blue;font-weight:bold;'>"+
"HttpContext.Current.Request.ServerVariables[\""+arr1[loop1] + "\"]</span>: "
);
String[] arr2=coll.GetValues(arr1[loop1]);
for (loop2 = 0; loop2 < arr2.Length; loop2++)
{
HttpContext.Current.Response.Write(arr2[loop2] );
} // end for 1
} // end for
break;
} // end switch
} // end EnumProperties
