Can't translate program from VB to C#

I have a Visual Studio VB.NET program with one form. The form has one text box and one button. You enter text in the text box, click the button, and your input is saved in a new text filed called TextFile1.txt. It works fine.  Here's the code for the Button1_Click.

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles     Button1.Click
        My.Computer.FileSystem.WriteAllText _
            ("c:\TextFile1.txt", TextBox1.Text, False)
        MsgBox("File saved as TextFile1.txt")

 End Sub


I tried to create the same program in Visual C#, but it doesn't work. Here's the code for the Button1_Click.

        private void Button1_Click(object sender, EventArgs e)
        {  
            System.IO.File.WriteAllLines
                (@"C:\TextFile2.txt", TextBox1.Text);
            Microsoft.VisualBasic.Interaction.MsgBox
                ("File saved as TextFile2.txt");
        }

I don't know how to make the C# version work. I'm going to attach both programs
to http://www.ee-stuff.com/Expert/Upload/upload.php as zip files because this page won't let me attach them.

"...but it doesn't work."

That's pretty vague.  What happens that shouldn't, or doesn't that should?

How about
private void Button1_Click(System.Object sender, System.EventArgs e)
{
	My.Computer.FileSystem.WriteAllText("c:\\TextFile1.txt", TextBox1.Text, false);
	Interaction.MsgBox("File saved as TextFile1.txt");

}

I get a dialog box that says "There were build errors. Would you like to continue and run the last  successful build?"  

I click No to close the box, and then these errors appear at the bottom of the IDE.

Error1 on line 22 says "The best overloaded method match for 'System.IO.File.WriteAllLines(string, string[])'
has some invalid arguments"      
        
Error 2 on LIne 22 says"Arugment2: cannot convert 'string to 'string[]'

When I tried
            My.Computer.FileSystem.WriteAllText("c:\\TextFile1.txt", TextBox1.Text, false);
            Microsoft.VisualBasic.Interaction.MsgBox("File saved as TextFile1.txt");

I got this error
"The name 'My' does not exist in the current context"

Try:

private void Button1_Click(object sender, EventArgs e)
        {  
            System.IO.File.WriteAllLines(@"C:\TextFile2.txt", TextBox1.Text.ToString, Encoding.UTF8);
            Microsoft.VisualBasic.Interaction.MsgBox("File saved as TextFile2.txt");
        }

I see.  Try:

private void Button1_Click(object sender, EventArgs e)
    {  
      arrText = (string[])TextBox1.Text;"
      System.IO.File.WriteAllLines(@"C:\TextFile2.txt", arrText, Encoding.UTF8);
       Microsoft.VisualBasic.Interaction.MsgBox("File saved as TextFile2.txt");
     }


It looks like WriteAllLines is looking for an array as its second parameter.  I'm not a C# guy, so I may have flubbed the cast as arrText.  If so, I'm sure you can fix it.

Use WriteAllText(), not WriteAllLines():
        private void Button1_Click(object sender, EventArgs e)
        {  
            System.IO.File.WriteAllText(@"C:\TextFile2.txt", TextBox1.Text);
            MessageBox.Show("File saved as TextFile2.txt");
        }

WriteAllText() did the trick. Thank you!
