嗨Techies，

我的应用程序中有一个要求，我需要从其他应用程序创建的浏览器中读取Cookie.我无法读取Cookie值. Cookie是会话cookie，当浏览器丢失会话时，该cookie将会过期.我使用以下代码在浏览器中读取了所有cookie.但是，我找不到想要的Cookie.

Hi Techies,

I have a requirement in my application that i need to read a cookie from the browser which is created by the other application. I am not able to read the cookie value. The cookie is a session cookie which will expires when browser lost the session. I used the below code to read all the cookies in browser. But, i couldn''t get the cookie that i am looking for.

推荐答案

您可以使用以下函数获取Cookie值.

You can get the cookie value using following function.

getCookieValue("Cookie_key");

public static string getCookieValue(string strKey)
    {
        if (HttpContext.Current.Response.Cookies[strKey] != null && HttpContext.Current.Response.Cookies[strKey].Value + "" != "")
        {
            return HttpContext.Current.Response.Cookies[strKey].Value;
        }
        else if (HttpContext.Current.Request.Cookies[strKey] != null)
        {
            HttpContext.Current.Response.Cookies[strKey].Value = HttpContext.Current.Request.Cookies[strKey].Value;
            return HttpContext.Current.Request.Cookies[strKey].Value;
        }
        else
        {
            return "";
        }
    }
