Every textbox has a MaxLength property you could test for . Default it is set to 32767 chars.

Text boxes have a .Length API call which will tell you how many characters are currently in the text box. It looks something like this:

if(textBox1.Text.Length >= 50)
{
	MessageBox.Show("Invalid input. Value must be less than 50 characters");
}
else
{
      //Acceptable input length
}
