我们需要在遇到问题时访问.aspx页面中的c#变量

请指导我们？

首先,在aspx标记中保护您想要访问的任何变量.

然后在page_load方法中,调用DataBind();

然后在你的标记中你可以这样做：

<%# VariableName %>

“<％=”序列只能在服务器控件的某些上下文中使用.序列“<％#”用于DataBound控件,可以在ASPX页面标记的任何上下文中使用.调用DataBind();允许您在页面的任何位置使用它(几乎).

这是我的一个古老的宠儿.我可以用我编程的所有语言来实现,但不能用Delphi实现.

…

A popular debugging feature in Delphi 8 and C# Builder is the capability to select a particular frame from the call stack using the Local Variables dialog Box. This feature is Now available for the Borland Win32 Debugger.

With the Borland Win32 Debugger loaded,view the Local Variables dialog Box. (If this dialog Box is not already visible,select View | Debug Windows | Local Variables,or press Ctrl-Alt-L,to display it.) Initially,the values of variables local to the current function that the debugger is in are shown. To view local variables in one of the methods earlier in the call chain,select the method name from the drop-down menu.

在Delphi 7中,局部变量视图始终显示执行中断的函数的局部变量.

到目前为止尝试了这个,检查这个示例类

type
  TFoo=class
   strict private class var Foo: Integer;
   public
   constructor Create;
  end;

constructor TFoo.Create;
begin
  inherited;
  Foo:=666;
end;

//this function works only if I declare the foo var as 
//strict private var Foo: Integer;
function GetFoovalue(const AClass: TFoo): Integer;
begin
  Result := PInteger(PByte(AClass) + 4)^
end;

如您所见,函数GetFoovalue仅在foo变量未声明为类var时才起作用.

问题是我必须如何修改GetFoovalue以获得Foo的值,当声明为严格私有类var Foo：Integer时;

示例：

type
  TFoo = class
  strict private class var
    Foo : Integer;
  end;

  TFooHelper = class helper for TFoo
  private
    function GetFoovalue : Integer;
  public
    property Foovalue : Integer read GetFoovalue;
  end;

function TFooHelper.GetFoovalue : Integer;
begin
  Result:= Self.Foo;  // Access the org class with Self
end;

function GetFoovalue( F : TFoo) : Integer;
begin
  Result:= F.GetFoovalue;
end;

Var f : TFoo;//don't need to instantiate since we only access class methods

begin
  WriteLn(GetFoovalue(f));
  ReadLn;
end.
