How to get the TResult of Func in C#?

I am new to func, I have define the Func like below,

 private Func<int, Type, GridCell> getGridCell;
 public Func<int, Type, GridCell> GetGridCell
  {
    get
     {
       return getGridCell;
     }
   set
    {
      getGridCell = value;
    }
  }

And I don't know how to get the TResult that is GridCell. Could you please suggest on this?

A Func doesn't have a result until you call it. So GetGridCell doesn't have a value of type GridCell - it's a function which can be called to get a GridCell. For example:

Func<int, Type, GridCell> function = GetGridCell;
GridCell cell1 = function(1, typeof(string));
GridCell cell2 = function(10, typeof(DateTime));

How exactly that is computed depends on the value of GetGridCell - it could do anything, basically, because it's just a function.

Note that this isn't specific to Func types - it's the general idea of delegates.
