从 ExcelDataReader 数据集中保存值

Question

I'm using C# to read an Excel file using ExcelDataReader and ExcelDataReader.DataSet . I'm not too familiar with parsing DataSets so I was wondering how to save the values from each row in a particular column in the Excel. I need the code to pull all the values from the first column of the spreadsheet I load.

public void ExcelFileReader(string path)
{
    var stream = File.Open(path, FileMode.Open, FileAccess.Read);
    var reader = ExcelReaderFactory.CreateReader(stream);
    var rowCount = reader.RowCount;

    result = reader.AsDataSet(new ExcelDataSetConfiguration()
    {
        ConfigureDataTable = (DataTableReader) => new ExcelDataTableConfiguration()
        {
            UseHeaderRow = true
        }
    });

    var tables = result.Tables.Cast<DataTable>();
    var dataTable = result.Tables[0].Columns[0].ToString();
    foreach(DataTable table in tables)
    {
        dataGridView1.DataSource = table;
    }
}

The line: var dataTable = result.Tables[0].Columns[0].ToString(); will get me the name of the header for the column I want but how do I parse through the rows of column 1 and save all the values?

Answer 1

You have to iterate throught the rows of the table and then get the column 0 value.

foreach (DataRow row in dataset.Tables[0].Rows)
{
    Console.WriteLine(row[0]);
}

This will write all the values from the first column (index 0).
