List<object> with indexed String

Question

0.00/5 (No votes)

See more:

usually WE try to return the object of the List<object> along with the integer index like example below:

C#

public List<object> data = new List<object>();
public object Test(int index)
{
   return data[index];
}

But I would like to do is, I wanting to replace the indexed integer to indexed string like below:

C#

public List<object> data = new List<object>();
public object Test(string indexName)
{
   return data[indexName];
}
void main()
{
....
((ClassA)Test["AttributeNo1"]).Hello1();
((ClassA)Test["AttributeNo1"]).Hello2("blabla");
((ClassA)Test["AttributeNo1"]) = new ClassA();
...
((ClassA)data["AttributeNo1"]).Hello1();
((ClassA)data["AttributeNo1"]).Hello2("blabla");
((ClassA)data["AttributeNo1"]) = new ClassA();
...
}

Is there anyway possible to make so? Or something similiar with it, just like MySQL DataReader way, that appears just like:

C#

DataReader reader ....
return reader["AttributeNo1"];

Use Dictionary[^]:

C#

public Dictionary<string,object> data = new Dictionary<string,object>
public object Test(string indexName)
{
   return data[indexName];
}
