Solution 1

For opening the file you need a OpenFileDialog.
Set the OpenFileDialog filter property to ".xls",".txt" to show only the files you want.

On your upload button click event use:
openfiledialog.showdialog()

On the OpenFileDialog FileOk Event you put your code for read the file contents and displaying them on textbox.

Here's some sample code, is VB but is easily convertible to C#:
You need to add a reference to Microsoft.Office.Interop.Excel.

Dim oXL As Microsoft.Office.Interop.Excel.Application
Dim oBook As Microsoft.Office.Interop.Excel.Workbook
Dim oSheet As Microsoft.Office.Interop.Excel.Worksheet
Dim vValue As Object

oXL = New Microsoft.Office.Interop.Excel.Application
oBook = oXL.Workbooks.Open(OpenFileDialog1.FileName)
oSheet = oBook.Worksheets("Sheet1")
'Here you have cell value, just build a loop to get the data you want
'This will loop through all rows in the first column

For i As Integer = 0 To oSheet.Rows.Count
vValue = vValue + ";" + oSheet.Cells(1, 1).Value
Next

myTextBox.Text = vValue
