How Can I Retrieve Excel Sheet Names in Their Original Order Using OLEDB?

Acquiring Excel Sheet Names in Sequential Order with OleDb

In the realm of spreadsheet operations, obtaining a list of Excel sheet names in the precise order defined in the workbook can be a crucial task. To accomplish this with OleDb, a specific approach is required.

Originally, utilizing OleDbConnection.GetOleDbSchemaTable() to retrieve sheet names was attempted, but it encountered an issue: alphabetical sorting. This disrupted the intended order of names and posed a challenge in mapping them to corresponding sheet numbers.

Thankfully, a solution exists that circumvents this hindrance: iterating through the sheets sequentially from index 0 to the total count of names. This guarantees that the names are retrieved in the desired order.

For those seeking an OLEDB-based approach, the following code sample demonstrates how to retrieve Excel sheet names in their sequential order:

private String[] GetExcelSheetNames(string excelFile)
{
    // Establish connection parameters
    string connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
        "Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";

    // Create connection and database linkage
    using (OleDbConnection objConn = new OleDbConnection(connString))
    {
        objConn.Open();

        // Retrieve schema table
        DataTable dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);

        // Initialize array for sheet names
        String[] excelSheets = new String[dt.Rows.Count];

        // Populate array with sequential sheet names
        int index = 0;
        foreach (DataRow row in dt.Rows)
        {
            excelSheets[index++] = row["TABLE_NAME"].ToString();
        }

        return excelSheets;
    }
}

By employing this technique, you can efficiently retrieve Excel sheet names in the exact order they appear within the workbook, enabling seamless user interactions based on name or index.
