UploadFile Management - Receive Data

Question

How to get data (reading a file) selected in a FileUpload control without FileUpload.SaveAs Methodon a server? Is it possible to immediately write it to some object?

Answer 1

Using FileUpload.FileContentgives you Streamto work.

See MSDN .

For instance:

void WriteFileLength()
{
    if (fileUpload.HasFile)
    {
        var fileStream = fileUpload.FileContent;
        var messageFormat = "The file is {0} bytes in length"
        Response.Write(string.Format(messageFormat, fileStream.Length));
    }
}

Answer 2

You have access to the download byte [] using

FileUpload1.FileBytes

where FileUpload1 is a control.
