In this tutorial, I will teach you how to save file .txt file using savefiledialog in c#. This method has the ability to save a text file using a SaveFileDialog class. SaveFileDialog is designed to control the file to be saved in the certain directory and it also provides a user-friendly interface to your form. See the procedure below to know how it works.

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application for c#. ps1

Step 2

Add a Richtexbox, button and a SaveFileDialog into the form. Do the form just like shown below. ps2

Step 3

Press F7 to open the code editor. In the code editor, create a method to save the file in the directory. 
  1.  
  2. private void save_file()
  3.         {
  4.             // instantiate a new class;
  5.             SaveFileDialog sv = new SaveFileDialog();
  6.             sv = saveFileDialog1;
  7.  
  8.             //With SaveFileDialog1
  9.             //    'IF THE USER NEGLECTS THE FILE ETENSION THEN, ADD THE DEFUALT EXTENSION.
  10.             sv.AddExtension = true;
  11.  
  12.  
  13.             //    'CHECK IF THE OUTPUT PATH ACTUALLY EXISTS 
  14.             //    'BEFORE CREATING A NEW FILE AND BEFORE OVERWRITING.
  15.             //    'THE FOLLOWING VALUES ARE IN ITS DEFUALT FORM.
  16.             sv.CheckPathExists = true;
  17.             sv.CreatePrompt = false;
  18.             sv.OverwritePrompt = true;
  19.             sv.ValidateNames = true;
  20.  
  21.             //    'GET AND SET THE DEFAULT EXTENSION
  22.             sv.DefaultExt = "txt";
  23.  
  24.             //    'FILLTERING THE FILES THAT YOU HAVE SAVED.
  25.             sv.Filter = "Text files (*.txt)|*.txt|" + "All files|*.*";
  26.             sv.FilterIndex = 1;
  27.  
  28.             if (sv.ShowDialog() == DialogResult.OK)
  29.             {
  30.                 System.IO.File.WriteAllText(sv.FileName, richTextBox1.Text);
  31.             } 
  32.         }

Step 4

Write the following code to execute the method that you have created when the button is clicked. 
  1.  
  2. private void button1_Click(object sender, EventArgs e)
  3.         {
  4.             save_file();
  5.         }  
  6.
