VB - ensuring a text file is written to and closed before opening to read from it

Beamson asked
Last Modified: 2017-11-22
I'd like to read the report or text file generated below (3rd from last line) into a textbox:
        Dim config As New MarketplaceWebServiceConfig
        config.ServiceURL = "https://mws.amazonservices.co.uk"
        Dim myClient As New MarketplaceWebServiceClient(AccessKey, SecretKey, ApplicationName, ApplicationVersion, config)
        Dim myRequest As New GetReportRequest
        myRequest.Merchant = SellerID
        myRequest.ReportId = reportId
        myRequest.Report = File.Open("C:\\report\" + reportId.ToString + ".txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)
        Dim myResponse As New GetReportResponse
        myResponse = myClient.GetReport(myRequest)

Open in new window

If I add a final line:
myTextbox.text = File.ReadAllText("C:\\report\" + reportId.ToString + ".txt")

Open in new window

I get "The process cannot access the file "xxx" because it is being used by another process."

What do I need to do to ensure the file is written to and closed before attempting to read from it?
