.net – HttpContext.Request和Request之间的区别

> HttpContext.Current.Request
> HttpContext.Request
>请求

这些是完全一样的吗？

在global.asax / global.asax.vb和default.aspx / default.aspx.vb中,这些对象的行为不同.

好的,我会尝试这个具体的这个时间.我应该使用以下哪项？

' File: global.asax
Protected Sub Application_BeginRequest(ByVal sender As Object,ByVal e As System.EventArgs)
    If Request.Url.Port = 80 Then
    'If HttpContext.Current.Request.Url.Port = 80 Then
    'If HttpContext.Request.Url.Port = 80 Then
        'do something
    End If
End Sub

' File: default.aspx
Public Sub Page_Load(ByVal sender As Object,ByVal e As System.EventArgs)
    If Request.Url.Port = 80 Then
    'If HttpContext.Current.Request.Url.Port = 80 Then
    'If HttpContext.Request.Url.Port = 80 Then
        'do something
    End If
End Sub
