[Solved] Simple way to get text from uploaded file?

[Aron]

Hello,
What's the easiest way to get the text of an uploaded file stream? Note I do not plan to save the actual file. Just get it's text and save that.

// save

if (RadUploadSQL.UploadedFiles.Count>0)

{

foreach (UploadedFile validFile in RadUploadSQL.UploadedFiles)

{

// open sql file

byte[] Filedata;

int Filesize;

Filesize = Convert.ToInt32(validFile.InputStream.Length);

validFile.InputStream.Read(Filedata, 0, Filesize); // What to do here?

}

}

Hello,
Solved it
Here's the solution in case anyone else is looking:

if (RadUploadSQL.UploadedFiles.Count > 0)
        {
            foreach (UploadedFile validFile in RadUploadSQL.UploadedFiles)
            {
                // open the text file
                using (StreamReader reader = new StreamReader(validFile.InputStream))
                    v.SqlScript = reader.ReadToEnd(); // set value to text files text
            }
        }

I'm having a similar problem. I'd like to upload a single text file to the server, and parse its contents. I can see the length is correct in theStream, so I know it has content before it hits the reader.

However when I try to use the StreamReader, it comes back with Nothing. What am I missing?

Here is my code:

Imports System.IO

 Protected Sub buttonSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles buttonSubmit.Click
    BindValidResults()
    BindInvalidResults()

    ' process file
    Dim theStream As Stream = RadUpload1.UploadedFiles(0).InputStream

    Using sr As New StreamReader(theStream)
      Dim line As String = sr.ReadLine()
      While Not line Is Nothing
        'split the line
        Dim tmpArray() As String = line.Split(Convert.ToChar("|"))
        Response.Write("ID" & tmpArray(0).ToString() & " Name:" & tmpArray(1).ToString() & "<BR>")
        line = sr.ReadLine()
      End While
    End Using

  End Sub

Hi Shane Woodruff,

I have tested your code on a sample page and it seems to work fine. I suggest that you put a breakpoint into your code and debug it see what exactly is going wrong. Is this issue reproduced only with a specific file or with all kinds of files? I am attaching my sample project that works fine. Can you reproduce the issue on it?

Kind regards,
