Hello mathieu_cupryk,

Depends what sort of text file you want. The simplest is to use the .WriteXML("MyFilename.xml") method of the dataset, the advantage being that you can use the corresponding .ReadXML method to read the contents back into a dataset at a later stage.

try the attached code
    private void WriteToTextFile()
    {
        DataSet ds = new DataSet();
        string strDSValue = "";
        //ds =data returned by u r query
        if (ds!=null)
         strDSValue = ds.GetXml(); ;
        System.IO.StreamWriter objStreamWriter = new System.IO.StreamWriter("test.txt");
        objStreamWriter.WriteLine(strDSValue);
        objStreamWriter.Close();
    }

Chandan_Gowda,

Don't see why you would use that over the WriteXML method as it includes an overload to specify the filename (which can be anything you want).

mathieu_cupryk,

That is why I ask, of course XML is simply text when you get down to it. I assume that you mean you would prefer something along the lines of CSV rather than XML. What happens then if you have multiple tables contained within your dataset? How would you like to output that - as seperate files or somehow as a seperate section within a single file? What do you want to do with the text file once you have output it?

All of these things are relevant and would help to decide what kind of approach to take in this situation.

mathieu_cupryk,

That just outputs it as XML anyway, I don't understand why (and Chandan even admits that it isn't) this is the best solution. If you want a filename ending in .txt then call it that using:

.WriteXML ("MyFilename.TXT")!
