Want to read data from different Excel worksheets in the same Excel file using selenium c#

Question

Have used ExcelDataReader NuGET Package.

This is the class setting it up -

    private static DataTable ExcelToDataTable(string fileName)
    {
        //open file and returns as Stream
        FileStream stream = File.Open(fileName, FileMode.Open, FileAccess.Read);
        //Createopenxmlreader via ExcelReaderFactory
        IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream); //.xlsx
                                                                                       //Set the First Row as Column Name
        excelReader.IsFirstRowAsColumnNames = true;
        //Return as DataSet
        DataSet result = excelReader.AsDataSet();
        //Get all the Tables
        DataTableCollection table = result.Tables;
        //Store it in DataTable
        DataTable resultTable = table["Sheet1"];
        //return
        return resultTable;
    }
   static List<Datacollection> dataCol = new List<Datacollection>();

public static void PopulateInCollection(string fileName)
    {
        DataTable table = ExcelToDataTable(fileName);

        //Iterate through the rows and columns of the Table
        for (int row = 1; row <= table.Rows.Count; row++)
        {
            for (int col = 0; col < table.Columns.Count; col++)
            {
                Datacollection dtTable = new Datacollection()
                {
                    rowNumber = row,
                    colName = table.Columns[col].ColumnName,
                    colValue = table.Rows[row - 1][col].ToString()
                };
                //Add all the details for each row
                dataCol.Add(dtTable);
            }
        }
    }
    public static string ReadData(int rowNumber, string columnName)
    {
        try
        {
            //Retriving Data using LINQ to reduce much of iterations
            string data = (from colData in dataCol
                           where colData.colName == columnName && colData.rowNumber == rowNumber
                           select colData.colValue).SingleOrDefault();

            //var datas = dataCol.Where(x => x.colName == columnName && x.rowNumber == rowNumber).SingleOrDefault().colValue;
            return data.ToString();
        }
        catch (Exception)
        {
            return null;
        }
    }


}

public class Datacollection
{
    public int rowNumber { get; set; }
    public string colName { get; set; }
    public string colValue { get; set; }
}

}

---

It called in the code like -

   //setting the excel file location
ExcelLib.PopulateInCollection(@"C:\Users\User1\Documents\data.xlsx");
//reading data from row 1 & column named middlename
xrmApp.Entity.SetValue("middlename", ExcelLib.ReadData(1, "middlename"));

I want to be able to use this code in different method and for each method I need different data. So is their anyway I can add a worksheet number parameter to the code so I can specify which worksheet to look into when reading the row number and column number.

Thanks!

Based on your description, you want to read the data from different worksheet in the same

excel file.

I suggest that you can convert the excel file to dataset and choose the datatable from the

dataset.

Like the following code:

Before that, please install nuget package ExcelDataReader and ExcelDataReader.DataSet both.

 class Program
 {
    static void Main(string[] args)
    {
        DataSet set = ExcelToDataSet("D:\\test.xlsx");
        DataTable table = set.Tables[0];   // first sheet
        string data = ReadData(table, 0, "TeacherName");// the first row and colunname is teachername
        Console.WriteLine(data);
        table = set.Tables[1];             //second sheet
        data = ReadData(table, 0, "StuName");// the first row and colunname is stuname
        Console.WriteLine(data);
        Console.ReadKey();

    }

    private static DataSet ExcelToDataSet(string fileName)
    {
        //open file and returns as Stream
        FileStream stream = File.Open(fileName, FileMode.Open, FileAccess.Read);
        //Createopenxmlreader via ExcelReaderFactory
        IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream); //.xlsx
                                                                                       //Set the First Row as Column Name
        DataSet result = excelReader.AsDataSet(new ExcelDataSetConfiguration()
        {
            ConfigureDataTable = (_) => new ExcelDataTableConfiguration()
            {
                UseHeaderRow = true
            }
        });
        //Get all the Tables
        //return
        return result;
    }

    static string ReadData(DataTable table,int row,string columnname)
    {
        return table.Rows[row].Field<string>(columnname).ToString();
    }


}

I created the following excel:

First sheet:

Second sheet:

If I run the above code, you will get the value of first row and first column of two sheet.
