Dictionary out of range

Basically I am asking is there a better way to do this below. This works so far when an element does not exist.

if (!sportsDictionary[sports.Team].Any(w => w.Team == sportsObject.Team))
{

if (sportsDictionary[sportsObject.Team].Count < sportsObject.Index)
{
int resize = sportsObject.Index - sportsDictionary[Sports.Team].Count;

for (int i = 0; i <= resize; i++)
{
sportsDictionary[Sports.Team].Add(new SportsObject());
}
}

sportsDictionary[Sports.Team].Insert(waypoint.Index, sportsObject);

}

this is all you really need to know below.

Dictionary sportsDictionary;

if (!sportsDictionary.ContainsKey(sports.Team))    
 {        
      sportsDictionary.Add(sports.Team, new List(10)); 
 }     
 else    
 {         
      sportsDictionary[sports.Team][Team.sportsId] = sports; 
     //Error: index out of range above
 } 

Hi David Smith,

Your question incomplete, because have no idea what type of your parameters and all that.

Please share or explore you coding parts for better understand.
