No overload for method 'this' takes 2 arguments error

I'm trying to parse an element of a string array to an int.

Code:

---


  public static void child_calc()
        {
         


            if (jw.totalcount == hk1Class.rows)
            { jw.linked = true; }


            if (jw.linked == true)
            {
                linkedClass.linked_parent_setup();


                  // clone dictionary to enable converting to array
                    Dictionary<string, int> childcolor1 = new Dictionary<string, int>();
                    Dictionary<string, int> colorscopy = new Dictionary<string, int>(childcolor1);


                // convert dictionary to array
                    int[] values = childcolor1.Values.ToArray();
                    string[] keys = childcolor1.Keys.ToArray();


                // clone dictionary to enable converting to array
                    Dictionary<string, string> childgeneo1 = new Dictionary<string, string>();
                    Dictionary<string, string> geneocopy = new Dictionary<string, string>(childgeneo1);
                // convert dicitionary to arry
                    string[] keys1 = childgeneo1.Keys.ToArray();
                    string[] values1 = childgeneo1.Values.ToArray();




              // setting up the print parameters
                int z = 0; //local var
                while (z < (jw.totalcount + 1))
                {
                    // calculate color type %
                    string dz = childcolor1[z, 1]; // copy array value to local string
                    int colorpct1 = Int32.Parse(dz); // copys  array value to local int
                    colorpct1 = ((colorpct1 / jw.totalcount) * 100); // converts to a percentage
                    jw.colorpct = colorpct1; // converts the int to a string so % sign can be appended


                    // append % to end of string
                    string pct2 = "%";
                    jw.colorpct += pct2;
                   
                 
                    // print to screen
                    Console.WriteLine("{0}, {1}, {2},",
                      childcolor1[z, 0],
                      childgeneo1[z, 0],
                      jw.colorpct);
                } // end while


            } // end if
       
            return;
        } // end child_calc

---

this line is throwing the no overload error:

Code:

---

string dz = childcolor1[z, 1]; // copy array value to local string

---

My end result is to have converted 'string dz' to an int.
What am I missing?

Dictionary<string, int> should be indexed with one string, you're trying to index it with two integers.

Furthermore you're trying to assign the resulting integer to the String dz.

I'm just not seeing :(
Can you please show what in my code is wrong and the proper way to do it.

My train of thought was that since I converted to an array; I could treat it like a normal 2d array.

woah. foreach a keyvaluepair instead of all that.

You're converting the keys and values separately from the dictionary, which creates 2 1-dimensional arrays, not 1 2-dimensional array.

Also:

Code:

---

jw.colorpct = colorpct1; // converts the int to a string so % sign can be appended

---

This isn't right either. You can't just assign an int to a string to make it convert it.

I'm not sure what the heck your dictionaries are supposed to contain, but it definitely looks like you're doing things the hard way.

Dictionary childcolor1 the key is color name and the value is how many.
Dictionary chidgeneo1 the key is geneotype and value is color name.

I need to output to screen color name, corresponding geneotype, (chlidcolor1 value as a %) on 1 line.

I google and see how to foreach keyvaluepair into a list. I'm just not seeing/grasping how to do that into a 2d array.

As for assigning the int to a string; I'm scrapping that and will instead print % behind the value.

I don't see why you're so stuck on 2d arrays. The dictionary lets you do all the lookups.

Code:

---

        static void Main(string[] args)
        {
            Dictionary<string, int> colorAmounts = new Dictionary<string, int>();
            colorAmounts.Add("green", 4);
            colorAmounts.Add("red", 12);
            colorAmounts.Add("blue", 7);

            Dictionary<string, string> geneotypes = new Dictionary<string, string>();
            geneotypes.Add("fluffy", "green");
            geneotypes.Add("bunny", "red");
            geneotypes.Add("feet", "blue");

            int totalChildren = colorAmounts.Sum(c => c.Value);  // 4 + 12 + 7 in this example

            foreach (string type in geneotypes.Keys)
            {
                string color = geneotypes[type];
                Console.WriteLine("Geneotype: {0}, Color: {1}, Percent: {2}%", type, color, (double)colorAmounts[color] / totalChildren * 100);
            }
        }

Code:

---

Geneotype: fluffy, Color: green, Percent: 17.3913043478261%
Geneotype: bunny, Color: red, Percent: 52.1739130434783%
Geneotype: feet, Color: blue, Percent: 30.4347826086957%
Press any key to continue . . .

Doing this on an iPhone is not easy as I thought... Excuse the case and any rough typos...

Code:

---

Dictionary<string, string> listA = new dictionary<string, string>();
Dictionary<string, int> listB = new dictionary<string, int>();

Foreach(keyvaluepair kvp in listA)
{
console.writeline(kvp.key + kvp.value + " " + listB[kvp.value].tostring());
}

Pretty easy to pull the data this way, once you have two dictionaries that share a common value I'm sure you would be better off building a custom class and make it into a list of your own using generics.
