How to read values from dictionary value collection and make it comma seperated string? - c#-4.0

Question

I have a dictionary object as under
Dictionary<string, List<string>> dictStr = new Dictionary<string, List<string>>();
dictStr.Add("Culture", new List<string>() { "en-US", "fr-FR" });
dictStr.Add("Affiliate", new List<string>() { "0", "1" });
dictStr.Add("EmailAddress", new List<string>() { "sreetest#test.com", "somemail#test.com" });
And I have an entity as under
public class NewContextElements
{
public string Value { get; set; }
}
What I need to do is that for every value in a particular index of the dictionary value collection, I have to make a comma separated string and place it into List collection.
e.g. the NewContextElements collection will have (obviously at run time)
var res = new List<NewContextElements>();
res.Add(new NewContextElements { Value = "en-US" + "," + "0" + "," + "sreetest#test.com" });
res.Add(new NewContextElements { Value = "fr-FR" + "," + "1" + "," + "somemail#test.com" });
I was trying as
var len = dictStr.Values.Count;
for (int i = 0; i < len; i++)
{
var x =dictStr.Values[i];
}
no it is of-course not correct.
Help needed

Answer 1

Try this:
Enumerable.Range(0, len).Select( i =>
new NewContextElements {
Value = string.Join(",", dictStr.Values.Select(list => list[i]))
}
);
len is the number of items inside the individual lists (in your example, it's two).

Answer 2

This isn't a slick as #dasblinkenlight's solution, but it should work:
Dictionary<string, List<string>> dictStr = new Dictionary<string, List<string>>( );
dictStr.Add( "Culture", new List<string>( ) {"en-US", "fr-FR"} );
dictStr.Add( "Affiliate", new List<string>( ) {"0", "1"} );
dictStr.Add( "EmailAddress", new List<string>( ) {"sreetest#test.com", "somemail#test.com"} );
int maxValues = dictStr.Values.Select(l => l.Count).Max();
List<NewContextElements> resultValues = new List<NewContextElements>(dictStr.Keys.Count);
for (int i = 0; i < maxValues; i++) {
StringBuilder sb = new StringBuilder();
string spacer = string.Empty;
dictStr.Keys.ForEach( k => {
sb.AppendFormat( "{0}{1}", spacer, dictStr[k][i] );
spacer = ", ";
} );
resultValues.Add( new NewContextElements( ){ Value = sb.ToString() });
}

Answer 3

do you mean transform your data like
1 2
3 4
5 6
to
1 3 5
2 4 6
try this block of code? it can be optimized in a few ways.
var res = new List<NewContextElements>();
int i = dictStr.values.count()
for (int i=0; i < len; i++) {
NewContextElements newContextElements = new NewContextElements();
foreach (List<string> list in dictStr) {
if (newContextElements.value() == null ) {
newContextElements.value = list[i];
} else {
newContextElements.value += ", " + list[i] );
}
}
res.add(newContextElements);
}
let me know if there are problems in the code, most like there is when you write it without a real ide.
