Visual Studio - Write To A Text File

Visual Studio C# Write to a File:

In order to test this code, do the following:

Create a new Windows Application

Add a New form

Add a textbox to the form; use the default name for the textbox.

Make sure to change the Multiline Property of the textbox to True.

After changing the Multiline Property of the textbox to True, make the textbox larger in order to fill the form, but leave enough room at the top to add a button.

Add a button to the form above the textbox.

Rename the button, ‘pbSave’.

Paste the code below into the Click event of the ‘Save’ button.

Type some text into the text box, and click the ‘Save’ button.

       

 private void pbSave_Click(object sender, EventArgs e)
        {

            try
            {
                System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\Test\TextFile.txt");
                file.WriteLine(textBox1.Text);
                file.Close();
            }
            catch (System.Exception err)
            {
                System.Windows.Forms.MessageBox.Show(err.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
