LinqToExcel to load Dictionary

Question

I have the following worked out but quite less than elegant. I\'d like to work this out with ToDictionary if possible. Thank you for any help as I\'m pretty new.

Answer 1

You can filter the values using a sigle LINQ query.This will return the name and number columns in the excel:

    var sampleExcel = new ExcelQueryFactory(@"I:\Book1.xlsx");
    var sampleWorksheet = from workSheet in sampleExcel.Worksheet("Sheet1") select workSheet;
    var selectedValues = from excelRow in sampleExcel.Worksheet()
       select new { name = excelRow[0], number =Convert.ToInt32(excelRow[1]) };
        foreach (var item in selectedValues)
        {
            Console.WriteLine(string.Format("Name is {0} ,number is {1}",item.name,item.number));
        }


        Dictionary dict = new Dictionary();

        foreach (var item in selectedValues)
        {
            dict.Add(item.number, item.name);
            Console.WriteLine(string.Format("Name is {0} ,number is {1}", item.name, item.number));
        }

Equivalent lambda expression for the above LINQ query:

var selectedValues1 = sampleExcel.Worksheet().Select(x => new { name = x[0], number = x[1] });
