Global的非静态方法 [英] Global's non static methods
问题描述
Global对象可以使用非静态方法吗？
如果答案是肯定的，那么如何在页面中访问它们？
我在Global.asax.cs中有以下属性，但是当我尝试在
页面中使用它时，我收到错误需要对象引用nonstatic
字段，方法或属性CurrentDisplayName"：
谢谢，
Alan
公共字符串CurrentDisplayName
{
get
{
string s;
try
{
s =会话[LLCConstants.SESSION_INDEX_DISPLAYNAME] .ToString（）;
}
catch（例外e）
{
s ="？" ;;
}
返回s;
}
设定
{
会话[LLCConstants.SESSION_INDEX_DISPLAYNAME] =价值;
}
}
这是有道理的。
你必须实例化一个您可以参考之前的类型为Global的实例
a非静态方法。
全球g = new Global（）;
回复.Write（g.CurrentDisplayName）;
或者你可以将CurrentDisplayName声明为静态，你不需要
实例化一个Global类型的对象来引用它。 br />
公共静态字符串CurrentDisplayName
{
//你的实现。
}
Response.Write（Global.CurrentDisplayName）;
HTH，

我认为我们不能创建自己的Globa实例l对象。
我确信ASP.NET框架为我们创建了实例。
基于微软在kb＃312607中提到的内容，我应该是能够通过使用Page.ApplicationInstance属性获得对该实例的访问权限，但它不会对我有用。
对我来说不起作用。这意味着我无法访问非静态成员！
并且他们不会出现在IDE inlisense中

我认为这是一个文档中的错误。它应该读取
每个页面都包含类型为
" HttpContext的强类型Context属性。要获得与您的请求关联的全局类的实例
，您可以：
全球g = Context.ApplicationInstance为全局;
if（g！= null）
{
//聚会g
}
希望有所帮助。

Hi,
Can Global object have non-static methods?
If answer is yes, then How can I access them in pages?
I have following property in Global.asax.cs, but when I try to use it in
pages, I receive error "An object reference is required for the nonstatic
field, method, or property CurrentDisplayName":
Thanks,
Alan
public string CurrentDisplayName
{
get
{
string s;
try
{
s = Session[LLCConstants.SESSION_INDEX_DISPLAYNAME].ToString();
}
catch (Exception e)
{
s = "?";
}
return s;
}
set
{
Session[LLCConstants.SESSION_INDEX_DISPLAYNAME] = value;
}
}
That makes sense.
You have to instantiate an instance of type Global before you can reference
a non-static method.
Global g = new Global();
Response.Write( g.CurrentDisplayName );
or you can declare CurrentDisplayName as static and you won''t need to
instantiate an object of type Global to reference it.
public static string CurrentDisplayName
{
//your implementation.
}
Response.Write( Global.CurrentDisplayName );

I don''t think we can create our own instance of Global object.
I am sure that ASP.NET framework creates the instance for us.
Based on what microsoft mentioned in kb#312607, I should be able to have
access to that instance by using Page.ApplicationInstance property, But it
doesn''t work for me. That means I don''t have access to non-static members!
and they don''t appear in IDE inlisense

I think that is a bug in the documentation. It should probably read
"every page includes a strongly-typed Context property of type
"HttpContext". To get to the instance of the Global class associated
with your request, you can do:
Global g = Context.ApplicationInstance as Global;
if(g != null)
{
// party on g
}
Hope that helps.
