Question

i have an excel with multi-sheets that i want to import

Excel creates a hidden sheet each time you filter on a sheet and all though this sheet should not be available when retrieving the sheet names. Here is a piece of code that will help you get the sheet names using System.Data.OleDb:

class Retriever
{
    public List<SheetName> GetSheetNames(OleDbConnection conn)
    {
        List<SheetName> sheetNames = new List<SheetName>();
        if (conn.State != ConnectionState.Open)
        {
            conn.Open();
        }
        DataTable excelSchema = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
        foreach (DataRow row in excelSchema.Rows)
        {
            if (!row["TABLE_NAME"].ToString().Contains("FilterDatabase"))
            {
               sheetNames.Add(new SheetName() { sheetName = row["TABLE_NAME"].ToString(), sheetType = row["TABLE_TYPE"].ToString(), sheetCatalog = row["TABLE_CATALOG"].ToString(), sheetSchema = row["TABLE_SCHEMA"].ToString() });
            }
        }
        conn.Close();
        return sheetNames;
     }
} 

class SheetName
{
     public string sheetName { get; set; }
     public string sheetType { get; set; }
     public string sheetCatalog { get; set; }
     public string sheetSchema { get; set; }
}
