How to write the content of a dictionary to a text file?

Question

I have a dictionary object of type Dictionary

and trying to use StreamWriter to output the entire content to a text file but failed to find the correct method from the Dictionary class.

using (StreamWriter sw = new StreamWriter("myfile.txt"))         {             sw.WriteLine(dictionary.First());          } 

I can only retrieve the first element and it is bounded by a square bracket plus a comma separator in between as well:

[Peter, Admin]

and would be nice to have [Peter Admin] (without the comma)

Answer 1

File.WriteAllLines("myfile.txt",     dictionary.Select(x => "[" + x.Key + " " + x.Value + "]").ToArray()); 

(And if you're using .NET4 then you can omit the final ToArray call.)

Answer 2

You need to loop over the entries yourself:

using (StreamWriter file = new StreamWriter("myfile.txt"))     foreach (var entry in dictionary)         file.WriteLine("[{0} {1}]", entry.Key, entry.Value);
