私は外部テキストファイルから配列を読み込み、その月を等価の値を保持する配列に変換する必要があります。 1月= 1月、2月= 2など。そのため、クイックソートを通過させることができます。Quicksortで使用される数に数を変換する

//Read external files into arrays.
string[] Month = File.ReadLines(@"Month.txt").ToArray();
string[] Year = File.ReadLines(@"Year.txt").ToArray();
//Convert arrays from string to double to be used in sort.
double[] YearSort = Array.ConvertAll(Year, double.Parse);
int UserInput1;
//Create new array that will hold selected array to be used in sort.
double[] data = new double[1022];
//Prompt user to select action.
Console.WriteLine("Press 1 to Sort by month or 2 to sort by year.");
UserInput1 = Convert.ToInt32(Console.ReadLine());
if(UserInput1 == 1)
{
Array.Copy(Month,data,1022);
QuickSort(data);
for (int i = 0; i < 1022; i++)
Console.WriteLine(data[i]);
Console.WriteLine();

私は私の月の文字列で月を置き換えるだろうか?彼らは配列の中にあり、手作業で多くを書く方法があります。 – ConfusedProgrammer
@ConfusedProgrammerは私の編集を参照してください。なぜあなたは 'MonthToDouble()'メソッドを作り、それを使わなかったのですか? – Quantic
