foreach with a string and Hashtable

[Dayton2]

Is it possible to search through a Hashtable by a string using foreach? I am new to C# and seem to be struggling with correctly implementing the foreach statement. I am attempting to grab each word from a readline and put them individually in a hashtable. This is code that I am working with...

Hashtable table = new Hashtable();
StreamReader sr = File.OpenText(FILE_NAME);
String linetext = sr.ReadLine();
int i = 0;

foreach (string s in linetext)
{
     table.Add(i, s);
     i++;
}
[\code]
The error that I am getting is "cannot convert 'char' to 'string'", but I am never declaring a char???
Any suggestions???
Thanks!!

I'm pretty sure the error is with this line:

foreach (string s in linetext)

What is essentially happening is you are moving through a collection of chars not strings (strings are just an array of characters). The following code would be correct, but not what you are looking for:

foreach (char c in linetext)

You are attempting to add each "word" in the linetext string to the hashtable? If this is correct try this:

string[] words = linetext.Split(new char[] {' '});
foreach(string s in words)
...

The Split method breaks the string into an array of words.

I hope this helped!
