To a one-dimensional array, two-dimensional arrays and jagged arrays as elements in a Dictionary, you would like to use a custom FromKeyToValue function according to the key to obtain the value, wrote a piece of code, but many problems the following code,
using System;
Using System. Collections. Generic;
Using System. Linq;
Using System. The Text;
Using System. The Threading. The Tasks;

The namespace ConsoleApp1
{
The class MyArray on
{
Public int no;
Public string [] Numbers;
Public string [and] names;
Public string [] [] scores;

Public MyArray on ()
{
This. No=0;
}


Public MyArray on (string [] Numbers)
{
This. No=1;
This. Numbers=Numbers;
}
Public MyArray on (string [and] names)
{
This. No=2;
This. Names=names;
}
Public MyArray on (string [] [] scores)
{
This. No=3;
This. Scores=scores;
}


Void FromKeyToValue (string key)
{
Dictionary Dic=new Dictionary (a);

String [] mf3.

String [and] siblings;

String [] [] renyudi;

MyArray on v1=Dic [key];
Int No=v1. No;

The switch (No)
{
Case 1:

{foreach (string I mf3 in) System. The Console. WriteLine (I); }
break;
Case 2:

The foreach (string I in siblings) {Console. Write (" {0} ", I); }
break;
Case 3:

The foreach (string [] I in renyudi)
{
The foreach (string j in I)
{
Console. WriteLine (j);
}
}
break;
Default:
Console. WriteLine (" error!" );
break;
}
}







Class Program
{
The static void Main (string [] args)
{
Dictionary Dic=new Dictionary (a);

String [] mf3={" c ", "c + +", "c #"};
MyArray on myArray1=new MyArray on (mf3);
Dic. The Add (" zhao ", myArray1);

Siblings, string []=new string [and] {{" Mike ", "Amy"}, {" Mary ", "Albert"}};
MyArray on myArray2=new MyArray on (siblings);
Dic. The Add (" money ", myArray2);

String [] [] renyudi=new string [2] [] {new string [] {" Mike ", "Amy", "Albert}", new string [] {" Beijing ", "Shanghai", "Tianjin", "through", "Xiamen"}};
MyArray on myArray3=new MyArray on (renyudi);
Dic. The Add (" sun ", myArray3);

MyArray on. FromKeyToValue (" money ");

}
}
}
}
