I have an object
Dictionary<int,> temp = new Dictionary<int,>();
The values in temp are:

1 s1
  s2
  s3
2 s1
  s2

I want to transform it into object
Dictionary<string,int[]> temp = new Dictionary< String,int[]>();
So i want final o/p as

[Update]
(On behalf of the OP)
@CPillani.. ur code working cool thanks
If the input,o/p type changed as follows.. please update ur code ..

i/p = Dictionary<uri,> d1 = new Dictionary<uri,>();
o/p = Dictionary<string[],> socialTermUriNew = new Dictionary<string[],>();

Sample Input data

http:\\localhost\a1.aspx a1
a4
a5
http:\\localhost\a2.aspx a1
a5
http:\\localhost\a3.aspx a4

Would be transform to Final o/p

a1 http:\\localhost\a1.aspx
http:\\localhost\a2.aspx

a4 http:\\localhost\a1.aspx
http:\\localhost\a3.aspx

a5 http:\\localhost\a2.aspx

Input object

Dictionary<uri, string[]=""> d1 = new Dictionary<uri, string[]="">();

Output Object

Dictionary<string, uri[]=""> d2 = new Dictionary<string, uri[]="">();

I think you should use property classes

C#

public class UserDefinedDictionary{
public string strText =new string();
public int[5] intArr=new int[5];
}

Dictionary<userdefineddictionary> udDictionary=new Dictionary<userdefineddictionary>();

udDictionary.strText="s1";
udDictionary.intArr[0]=1;
udDictionary.intArr[1]=2;

udDictionary.strText="s2"
udDictionary.intArr[0]=1;
udDictionary.intArr[1]=2;

udDictionary.strText="s3";
udDictionary.intArr[0]=1;

hope this might help you.

Do let me know if there is some syntax issue.

If you really need an array of integers the you have to iterate two times on the Dictionary.
e.g. (rd is the output Dictionary)

static void Main(string[] args)
    {
      string s1 = "s1";
      string s2 = "s2";
      string s3 = "s3";
      string[] a1 = { s1, s2, s3 };
      string[] a2 = { s1, s2 };
      

      Dictionary <int, string[]> d = new Dictionary<int, string[]>();
      d.Add(1, a1);
      d.Add(2, a2);
      

      Dictionary <string,int > cd = new Dictionary<string, int>();
      Dictionary <string, int> cdi = new Dictionary<string, int>();
      
      foreach (int k in d.Keys)
      {
        foreach (string s in d[k]) 
        {
          if (cd.ContainsKey(s))
            cd[s]++;
          else
            cd.Add(s, 1);
        }  
      }
      Dictionary<string, int[]> rd = new Dictionary<string, int[]>();


      foreach (string s in cd.Keys)
      {
        rd.Add(s, new int[cd[s]]);
        cdi.Add(s, 0);
      }

      

      foreach (int k in d.Keys)
      {
        foreach (string s in d[k])
        {
          rd[s][cdi[s]++] = k;
        }
      }
    }

[Update]
I don't get your new requirements completely (I cannot see proper declaration of your generic types), but I suppose you may modify the code I provided to fit your needs (it shouldn't be hard).
