Find # of Occurences & count in string using Collections/Generics

[DexterID]

Hi,

I tried so much working with this to get distinct Words and their count. I'm using ASP.NET 2.0.
And i also googled so much. I need HELP from anyone to get the required output.

1)Ex(String): The DOTNET is Very Cool! The Best.
2) Capture all the sequences like Spaces, Fullstops, Question Marks, Exclamations, Apostrophes, New Lines....(May be with RegEx?)
3)Split Words According to the above sequences
4)Get Distinct Words(Occurrenc es) and their count based on the input string in 1st statement.

Desired O/P:

The - 2
DOTNET - 1
Is - 1
Very - 1
Cool - 1
Best - 1


My Sample Code is as follows

ASPX:

<asp:TextBox ID="txtString" runat="server" TextMode="MultiLine" Height="100px" Width="500px"></asp:TextBox>
<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />
 

CS:

//Is it possible with Dictionary
SortedList<int, string> sl = new SortedList<int, string>();
 
protected void btnSubmit_Click(object sender, EventArgs e)
{
//Here i'ld like to check for Space, Question Mark, New Line, Exclamation, Apostrophe,.....
//Now i'm checking only for spaces. I need the above sequences loop also.
string[] Words = txtString.Text.Split(' ');//Space Split
for (int i = 0; i < Words.Length; i++)
{
sl.Add(i, Words[i]);
}
 
foreach (KeyValuePair<int, string> kvp in sl)
{
//I want to print Distinct Words and their Count
Response.Write(kvp.Value + " " + kvp.Key + "<br />");
}
}

Try this:

 
public static void WordsinString(string str)
        {
            char[] sep = new char[] { ' ' };
            Dictionary<string,int> strCount=new Dictionary<string,int>();
 
            string[] temp = str.Split(sep,StringSplitOptions.RemoveEmptyEntries);//, StringSplitOptions.RemoveEmptyEntries);
 
 
            foreach (string s in temp)
            {
                //Console.WriteLine(s);                
 
                if (strCount.ContainsKey(s))
                {
                    strCount[s] = (int)strCount[s] + 1;
                }
 
                else
                {
                    strCount.Add(s,1);
                }
 
 
            }
 
            foreach (KeyValuePair<string, int> p in strCount)
            {
                Console.WriteLine(p.Key+"  "+ p.Value);
            }
 
 
        }
 

or

public static void WordsInString(string str)
        {
            string[] temp = str.Split(new char[] { ' '}, StringSplitOptions.RemoveEmptyEntries);
 
            Dictionary<string, int> strCount = new Dictionary<string, int>();
 
            Regex rgx; //= new Regex(pat, RegexOptions.IgnoreCase);
            MatchCollection matches ;//= rgx.Matches(str);
 
            foreach (string s in temp)
            {
                rgx=new Regex(s, RegexOptions.IgnoreCase);
 
                matches = rgx.Matches(str);
 
                if (!strCount.ContainsKey(s))
                {
                    strCount.Add(s, matches.Count);
                }               
 
 
            }
 
            foreach (KeyValuePair<string, int> p in strCount)
            {
                Console.WriteLine(p.Key + "  " + p.Value);
            }
 
        }

char[] sep = new char[] { ' ', '.', '?', '!', '\n', '\r',',' };
worked perfectly. Thanks.
