Try something like this:

// read file content into a string
String fileContent = System.IO.File.ReadAllText(@"c:\file.dat");

// compare TextBox content with file content
if (fileContent.Equals(myTextBox.Text))
{
    // do something
}
else
{
    MessageBox.Show("Error!");
}

Take a look at StreamReader, that will allow you to read the file into your app.
