获取当前请求的 ASP.NET HttpContext，它封装了由 HTTP 服务器用来处理 Web 请求的所有 HTTP 特定的上下文。

public:
 property System::Web::HttpContext ^ Context { System::Web::HttpContext ^ get(); };

[System.ComponentModel.Browsable(false)]
public System.Web.HttpContext Context { get; }

[<System.ComponentModel.Browsable(false)>]
member this.Context : System.Web.HttpContext

Public ReadOnly Property Context As HttpContext

属性值

HttpContext

当前请求的 ASP.NET HttpContext。

BrowsableAttribute

例外

Context 为 null。

示例

以下示例使用 Context 属性获取服务器上的请求时间。

<%@ WebService Language="C#" Class="Util" %>
 
 using System;
 using System.Web.Services;
 
 public class Util: WebService {
   [ WebMethod(Description="Returns the time as stored on the Server",
   EnableSession=false)]
   public string Time() {
      return Context.Timestamp.TimeOfDay.ToString();
   }
 }

<%@ WebService Language="VB" Class="Util" %>
 
Imports System
Imports System.Web.Services

Public Class Util
    Inherits WebService
    
    <WebMethod(Description := "Returns the time as stored on the Server", _
        EnableSession := False)> _
    Public Function Time() As String
        
        Return Context.Timestamp.TimeOfDay.ToString()
    End Function
End Class

注解

XML Web service methods that have either the SoapRpcMethodAttribute or SoapDocumentMethodAttribute attribute applied to them with the OneWay property of set to true, do not have access to their HttpContext using the static Current property. 若要访问 ， HttpContext请派生实现 XML Web 服务方法 WebService 的类并访问 Context 该属性。
