Question

i have a dictionary

var dictionary = new Dictionary<string,string>{{"name","Smith"},{"age","20"}};

and i want to map it’s values to a class

class Person{ 
public string Name {get;set;} 
public string Age {get;set;}
}

i tried to do it in this way

public T Map<T>(Dictionary<string, object> row) 
{
      var p= new Person();
      if (row.ContainsKey("name")) Person.Name= row["name"];
      if (row.ContainsKey("age")) Person.Age= row["age"];
      return (T) p;
}

and the problem is that i fail at return type, i dont know how to cast T to class Person.
any ideas ?
Thanks.

Either:

public Person Map(Dictionary<string, object> row) 
{
      var p= new Person();
      if (row.ContainsKey("name")) Person.Name= row["name"];
      if (row.ContainsKey("age")) Person.Age= row["age"];
      return p;
}

Or:

public T Map<T>(Dictionary<string, object> row) 
 where T : Person
{
      var p= new Person();
      if (row.ContainsKey("name")) Person.Name= row["name"];
      if (row.ContainsKey("age")) Person.Age= row["age"];
      return (T) p;
}

Or:

public T Map<T>(Dictionary<string, object> row) 
 where T : Person, new ()
{
      var p= new T();
      if (row.ContainsKey("name")) Person.Name= row["name"];
      if (row.ContainsKey("age")) Person.Age= row["age"];
      return p;
}
