Write and read an introduction to two different syntaxes of Cookie on the Asp.net page

When doing asp.net development, this site is often used with Session and Cookie in order to store some information. The materials of Session will find a lot of relevant information on this site, while the materials related to Cookie are relatively few, so I would like to add 1. Here's the syntax for Cookie:

 
Response.Cookies[" The name of the cookie "].Value = " The home of the script "; 

Read Cookie grammar:

 
if (Request.Cookies[" The name of the cookie "] != null) 
{ 
string cookieValue = Request.Cookies[" The name of the cookie "].Value.ToString(); 
} 

If you're writing in a category, you need to write the full name,
Write Cookie grammar:

 
System.Web.HttpContext.Current.Response.Cookies[" The name of the cookie "].Value = " The home of the script "; 

Read Cookie grammar:

 
if (System.Web.HttpContext.Current.Request.Cookies[" The name of the cookie "] != null) 
{ 
string cookieValue = HttpContext.Current.Request.Cookies[" The name of the cookie "].Value.ToString(); 
}
