Usage of Dictionary along with KeyPairValue

HI,

I have a dictionary declared as follows:

public:
static Dictionary^> ^ language_string_table;

so by using for each loop key and values are loaded into that (which is written by someone else). Now i need by using the same for each loop i am able to access "key" of the Dictionary alone, please help me out how to access "value" of the Dictionary.

Thanks & Regards,
P.Karthik

As it's not usually obvious how to translate C# code to C++/CLI, try this:

#include "stdafx.h"

using namespace System;
using namespace System::Collections::Generic;

ref class MyClass
{
public:
static Dictionary^> ^ language_string_table;

static void MyMethod()
{
language_string_table = gcnew Dictionary^>();
List^ list1 = gcnew List();
list1->Add("oui");
list1->Add("non");
language_string_table->Add("French", list1);
List^ list2 = gcnew List();
list2->Add("yes");
list2->Add("no");
language_string_table->Add("English", list2);
for each(String ^ key in language_string_table->Keys)
{
List^ values = language_string_table[key];
for each(String ^ value in values)
{
Console::Write("{0} ", value);
}
Console::WriteLine();
}
}
};

int main(array ^args)
{
MyClass::MyMethod();
Console::ReadKey();
return 0;
}

I didn't really follow that but, if you want to do it using KeyValuePairs rather than the Keys collection, then use:

for each(KeyValuePair^> kvp in language_string_table)
{
List ^ values = kvp.Value;
for each(String ^ value in values)
{
Console::Write("{0} ", value);
}
Console::WriteLine();
}

Hi,

No this doesn't give the exact values of the key. This might work for the Dictionary which contains two Strings but my Dictionary contains one string and one list so if i use kvp.Value[0] and[1] it is giving the values of the 1st key by default based on the index provided.

If you can tell me a way where i can get whole list of a key. That is also fine. I can fetch data from that.

Thanks & Regards,
