如何在事件处理程序中获取HttpContext [英] How to obtain the HttpContext in Event Handler

问题描述

我正在尝试在MOSS的文档库中的事件处理程序中获取HTTPContext，但是我所拥有的只是HTTPContext的空值.当前，我在List上执行相同的操作并返回HTTPContext.有没有一种方法可以在文档库中获取HTTPContext来访问HTTPContext.Request方法?

I’m trying to obtain the HTTPContext within an Event Handler in a Document Library in MOSS, but all I have is a null value of the HTTPContext.Current, I do the same thing on a List and the HTTPContext is returned. There is a way to obtain the HTTPContext in Document Libraries to access the HTTPContext.Request method?

感谢您的帮助

这是代码:

public class TestContextListItemEventReceiver : SPItemEventReceiver
{
    HttpContext current;
    static object obj;

    /// <summary>
    /// Initializes a new instance of the Microsoft.SharePoint.SPItemEventReceiver class.
    /// </summary>
    public TestContextListItemEventReceiver()
    {
        current = HttpContext.Current;
    }

    public override void ItemAdding(SPItemEventProperties properties)
    {
        obj = current;  
    }
}

推荐答案

步骤1 声明:

    private HttpContext currentContext;
    static HttpContext _stCurrentContext;

第2步

currentContext = HttpContext.Current;      // in constructor

Step3

public override void ItemAdding(SPItemEventProperties properties)
                 _stCurrentContext = currentContext;

第4步

 public override void ItemAdded(SPItemEventProperties properties)
 if (_stCurrentContext.Request.Files[0].ContentLength > 0)
 HttpPostedFile uploadfile = _stCurrentContext.Request.Files[0];
