How to get each StateName TotalPopulation #2009

Answer 1

without using the Linq, here a solution
Dictionary<string,int> data=new Dictionary<string,int>(); // to store the words and count
string inputString = "I love red color. He loves red color. She love red kit.";
var details=inputString.Split(' '); // split the string you have on space, u can exclude the non alphabet characters
foreach(var detail in details)
{
// based on Ron comment you should trim the empty detail in case you have multi space in the string
if(!string.IsNullOfEmpty(detail) && data.ContainsKey(detail))
data[detail].Value++;
else
data.Add(detail,1);
}

Answer 2

What I did was, i broke the string into an array using the split function. Then looped through each of the element and checked whether that element has been parsed or not. If yes, the add the count by 1 else add the element to the dictionary.
class Program
{
static void Main(string[] args)
{
string inputString = "I love red color. He loves red color. She love red kit.";
Dictionary<string, int> dict = new Dictionary<string, int>();
var arr = inputString.Split(' ','.',',');
foreach (string s in arr)
{
if (dict.ContainsKey(s))
dict[s] += 1;
else
dict.Add(s, 1);
}
foreach (var item in dict)
{
Console.WriteLine(item.Key + "- " + item.Value);
}
Console.ReadKey();
}
}

Answer 3

Try this way
string inputString = "I love red color. He loves red color. She love red kit."; Dictionary<string, int> wordcount = new Dictionary<string, int>();
var words = inputString.Split(' ');
foreach (var word in words)
{
if (!wordcount.ContainsKey(word))
wordcount.Add(word, words.Count(p => p == word));
}
wordcount will have the output you are looking for. Note that it will have all entries for all words, so if you want for only a subset, then alter it to lookup against a master list.

Check the link given bellow.
Count Word
This example shows how to use a LINQ query to count the occurrences of a specified word in a string. Note that to perform the count, first the Split method is called to create an array of words. There is a performance cost to the Split method. If the only operation on the string is to count the words, you should consider using the Matches or IndexOf methods instead. However, if performance is not a critical issue, or you have already split the sentence in order to perform other types of queries over it, then it makes sense to use LINQ to count the words or phrases as well.
class CountWords
{
static void Main()
{
string text = #"Historically, the world of data and the world of objects" +
#" have not been well integrated. Programmers work in C# or Visual Basic" +
#" and also in SQL or XQuery. On the one side are concepts such as classes," +
#" objects, fields, inheritance, and .NET Framework APIs. On the other side" +
#" are tables, columns, rows, nodes, and separate languages for dealing with" +
#" them. Data types often require translation between the two worlds; there are" +
#" different standard functions. Because the object world has no notion of query, a" +
#" query can only be represented as a string without compile-time type checking or" +
#" IntelliSense support in the IDE. Transferring data from SQL tables or XML trees to" +
#" objects in memory is often tedious and error-prone.";
string searchTerm = "data";
//Convert the string into an array of words
string[] source = text.Split(new char[] { '.', '?', '!', ' ', ';', ':', ',' }, StringSplitOptions.RemoveEmptyEntries);
// Create and execute the query. It executes immediately
// because a singleton value is produced.
// Use ToLowerInvariant to match "data" and "Data"
var matchQuery = from word in source
where word.ToLowerInvariant() == searchTerm.ToLowerInvariant()
select word;
// Count the matches.
int wordCount = matchQuery.Count();
Console.WriteLine("{0} occurrences(s) of the search term \"{1}\" were found.", wordCount, searchTerm);
// Keep console window open in debug mode
Console.WriteLine("Press any key to exit");
Console.ReadKey();
}
}
/* Output:
3 occurrences(s) of the search term "data" were found.
