In my aspx page I have a HTML inputfile type which allows user to browse for a spreadsheet.Once the user choses the file to upload I want to read the content of the spreadsheet and store the content into mysql database table. I am using the following code to read the content of the uploaded file and convert it into a datatable in order into insert it into database table.
if (filMyFile.PostedFile != null) { // Get a reference to PostedFile object HttpPostedFile myFile = filMyFile.PostedFile; // Get size of uploaded file int nFileLen = myFile.ContentLength; // make sure the size of the file is > 0 if (nFileLen > 0) { // Allocate a buffer for reading of the file byte[] myData = new byte[nFileLen]; // Read uploaded file from the Stream myFile.InputStream.Read(myData, 0, nFileLen);...................................
Every morning we send out an email with a text file attached. This is a manual process so I am automating it.I am using an internal mail web service. Its last two parameters are a byte array which is the file contents and a string which is the file name. I passed (...gbytes, "test.txt") and the only thing wrong with it is text.txt is XML. I want it to be text (csv is fine because there is actually four columns that come from a datatable).So I am assuming what's making it XML is this code:
Code: System.IO.MemoryStream stream = new System.IO.MemoryStream(); System.Runtime.Serialization.IFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(); formatter.Serialize(stream, ds.Tables[0]); gbytes = stream.GetBuffer();
I am trying to search the Internet for how to convert a datatable to a byte array, but I can't find how to have it be text instead of XML. Also, another parameter our WS takes is a flag to say if it's XML, and I am setting this to false.

I have a dataset that has around 5 rows. I also have another Datarow() array that has an additional 3 rows which I would want to add to the dataset. The structure of both the Dataset Rows and the Datarow arrays are the same.
Do I have to perform a loop on the datatrow arrays and add them one by one? or is there a better way of adding them in one go ?
