Question

I have a winform with two data grids, and multiple text boxes. I want to give the user the option to export this data to a text document in a location of their choice on their drive. I also want the text document to be pre-formatted, and the values from the text boxes and datagrids to be plugged in.

Is it possible to pre-format a txt document using StreamWriter? And how to I go about giving the user the option of where to save this exported file?

Answer 1

You will have to format the string you want to write throught the StreamWriter.

using(StreamWriter sw = new StreamWriter(filePath)) {
    string firstLine = string.Concat("\n", string.Format(@"Customer number: {0}, Customer name: {1}", textBox1.Text, textBox2.Text));
    string secondLine = string.Format(@"Address: {0}", textBox3.Text);

    sw.WriteLine(firstLine);
    sw.WriteLine(secondLine);

    // Loop through your DataGridView.Rows or Cells and do the same.

    sw.Flush();
    sw.Close();
}

Output to file

Customer number: [12345678] Customer name: [customer name]
Address: [address]

Where the information between square brackets is the information input by the user through the TextBoxes.
