Dim ews As Excel.Worksheet
Dim fileName as string
fileName="D:\test.xls"
ewb = efa.Workbooks.Open(fileName)

Try this code:

Private Sub GetExcelSheetNames(ByVal fileName As String)
    Dim strconn As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & 
          fileName & ";Extended Properties=""Excel 12.0 Xml;HDR=YES"";"
    Dim conn As New OleDbConnection(strconn)

    conn.Open()

    Dim dtSheets As DataTable = 
              conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, Nothing)
    Dim listSheet As New List(Of String)
    Dim drSheet As DataRow

    For Each drSheet In dtSheets.Rows
        listSheet.Add(drSheet("TABLE_NAME").ToString())
    Next

    //show sheetname in textbox where multiline is true
    For Each sheet As String In listSheet
        TextBox1.Text = TextBox1.Text & sheet & vbNewLine
    Next

    conn.Close()

End Sub

An excellent library to handle xlsx files is EPPlus.

here is a sample code:

var existingFile = new FileInfo(path);
var sheets = new List<string>();
using (var package = new ExcelPackage(existingFile))
{
    sheets.AddRange(from worksheet in package.Workbook.Worksheets where worksheet.Dimension != null select worksheet.Name);
}
