Check how many same items a list contains

I have a list that contains names of Unity gameobjects.

I would like to have a method that I can call with the one of the names in the list, and it to return how many of that name is in the list.

How could I make this?

Let's say you have a List called namesList, you can make a for-loop and check for each item if it exists inside this list and count how many time you found it.

  public int countNameOccurance(string name, List<string> namesList) {
           int count = 0;

           for(int i=0; i < namesList.Count(); i++){
               if( namesList[i] == name){//check if the item exists in the list
               count++; 
               }
            }
          return count;
}

With Linq its ultra easy:

suppose you have a List of string named list and search for Name, so you could write:

using System.Linq;
:

private int Count(List<string> list, string NameSearch)
{
    return list.Count(n => n == NameSearch);
}
