如何將字符串存儲在cookie中並檢索它

Question

我想將用戶名存儲在cookie中，並在用戶下次打開網站時檢索它。是否可以創建一個在瀏覽器關閉時不會過期的cookie。我正在使用asp.net c＃來創建網站。而如何從提供保存用戶名和密碼

Answer 1

寫一個cookie

HttpCookie myCookie = new HttpCookie("MyTestCookie"); 
DateTime now = DateTime.Now; 

// Set the cookie value. 
myCookie.Value = now.ToString(); 
// Set the cookie expiration date. 
myCookie.Expires = now.AddYears(50); // For a cookie to effectively never expire 

// Add the cookie. 
Response.Cookies.Add(myCookie); 

Response.Write("<p> The cookie has been written."); 

讀一個cookie

HttpCookie myCookie = Request.Cookies["MyTestCookie"]; 

// Read the cookie information and display it. 
if (myCookie != null) 
    Response.Write("<p>"+ myCookie.Name + "<p>"+ myCookie.Value); 
else 
    Response.Write("not found"); 

Answer 2

除了什麼夏嘉曦說，如果你以後要停止瀏覽器更新相同的cookie使用：

HttpCookie myCookie = Request.Cookies["MyTestCookie"]; 
DateTime now = DateTime.Now; 

// Set the cookie value. 
myCookie.Value = now.ToString(); 

// Don't forget to reset the Expires property! 
myCookie.Expires = now.AddYears(50); 
Response.SetCookie(myCookie);
