How to save an stringbuilder's content to text file using SaveFileDialog?

Question

This is a winforms application.

In windows, I want the user to click and button, and then a popup should make the user select the path of where they want to save the file.

Answer 1

StringBuilder.ToString() can be passed to the TextStream.Write() method after creating the file.

Using the SaveFileDialog class, you can let the user select path and file name - in a standard way. Detailed examples in the doc.

Answer 2

You want the WriteAllText function.

using (SaveFileDialog dialog = new SaveFileDialog()) {
    if (dialog.ShowDialog(this) == DialogResult.OK) {
        File.WriteAllText(dialog.FileName, yourStringBuilder.ToString());
    }
}

Answer 3

StringBuilder.ToString() will get you the string.

Think no longer...

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication2 {
public partial class Form1 : Form {

    StringBuilder sb = new StringBuilder();

    public Form1() {
        InitializeComponent();

        sb.Append("This is going ");
        sb.Append("to be saved to a text file");
    }

    private void button1_Click(object sender, EventArgs e) {
        using (SaveFileDialog dlg = new SaveFileDialog()) {
            if (dlg.ShowDialog() == DialogResult.OK) {
                string fileName = dlg.FileName;
                SaveToFile(fileName);
            }
        }
    }

    private void SaveToFile(string fileName) {
        System.IO.TextWriter w = new System.IO.StreamWriter(fileName);
        w.Write(sb.ToString());
        w.Flush();
        w.Close();
    }
}
