TextWriter to TextBox

I have this TextWriter

    public static string txt = "./Logs.txt";
    public static TextWriter Logs = File.CreateText(txt);

I want to do something like this

    textBox1.Text = Logs.ToString();

or like this

    Logs.Flush();
    textBox1.Text = "";
    File.WriteAllText(txt, textBox1.Text);

I tried this too

public class ControlWriter : TextWriter
{
    private Control textbox;
    public ControlWriter(Control textbox)
    {
        this.textbox = textbox;
    }

    public override void Write(char value)
    {
        textbox.Text += value;
    }

    public override void Write(string value)
    {
        textbox.Text += value;
    }

    public override Encoding Encoding
    {
        get { return Encoding.ASCII; }
    }
}
//in the Form_Load
    TextWriter TW = new ControlWriter(textBox1);

It works but if the application starts to write continuously, the application will freeze....

I found the solution, here is the code I used

            Logs.Flush();
            using (FileStream Steam = File.Open(txt, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
            {
                using (StreamReader Reader = new StreamReader(Steam))
                {
                    while (!Reader.EndOfStream)
                    {
                        textBox1.Text = Reader.ReadToEnd();
                        break;
                    }
                }
            }

It seems like you want to read the data, but the question doesn't clearly describes it so I'll assume it.

If so, you can use TextReader ...

For how to use it, see this.

For Documentation

Edit

TextWriter Logs = File.CreateText(txt);
Logs.Close();
TextReader logs = File.OpenText(txt);
String data = logs.ReadToEnd();
logs.Close();

The above code works, you have to close the file which was opened for it to be used in any other process.

However, I would suggest using File to create and read the file. It's easy, you don't have to close the file after creation or reading, and it's short.

Example:

//To create file, where *txt* is your path.
File.WriteAllText(txt, "Whatever you want in file."); 
//To read your file, where *txt* is your path.
String data = File.ReadAllText(txt)
