Question:You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5.
The application allows users to post comments to a page that can be viewed by other users.
You add a SqlDataSource control named SqlDS.
You write the following code segment:
01 private void SaveComment()
02 {
03 string ipaddr;
04 â–º
05 SqlDS1.InsertParameters["IPAddress"].DefaultValue = ipaddr;
06 ...
07 SqlDS1.Insert();
08 }
You need to ensure that the IP Address of each user who posts a comment is captured along with the user's comment.
Which code segment should you insert at line 04?
A ipaddr = Server["REMOTE_ADDR"].ToString();
B ipaddr = Session["REMOTE_ADDR"].ToString();
C ipaddr = Application["REMOTE_ADDR"].ToString();
D ipaddr = Request.ServerVariables["REMOTE_ADDR"].ToString();
