You can use Session.Remove to remove using key from the session collection.

You can loop through you session collection

for (int i = 0; i < Session.Contents.Count; i++)
{
      var key = Session.Keys[i];
      var value = Session[i];

      //remove the key except one
      if(key!="youkey")
           Session.Remove(key);

}

Edit 1

As suggested by @JoachimIsaksson

 for (int i = 0; i < Session.Contents.Count; i++)
 {
      var key = Session.Keys[i];
      var value = Session[i];

      //remove the key except one
      if(key!="youkey")
      {
           Session.Remove(key);
           i++;
       }

 }

Edit 2

As suggested by @JoachimIsaksson I am not sure right one or not

 for (int i = 0; i < Session.Contents.Count; i++)
 {
      var key = Session.Keys[i];
      var value = Session[i];

      //remove the key except one
      if(key!="youkey")
      {
           Session.Remove(key);
           i--;
       }

 }

You could just simply save the variable you want to keep, clear all and put it back;

var value = Session["tokeep"]; 
Session.RemoveAll(); 
Session["tokeep"] = value;
