SYSK 66: .NET 1.1 and 2.0 Handles ASCII Encoding Differently?
My tests show that the answer is Yes… See it for yourself.
Create a windows app in VS 2003, add one text box and one button to a form and put the following code behind the button click:
// A bunch of bytes represented by their code
string[] input = "98 22 248 167 95 213 187 61 95 34 182 249 149 140 222 222 63 192 134 194".Split(' ');
byte[] byteData = new byte[input.Length];
for (int i = 0; i < byteData.Length; i++ )
{
byteData[i] = (byte) int.Parse(input[i]);
}
// this works the same in 1.1 and 2.0
//textBox21Text = System.Text.Encoding.UTF8.GetString(byteData);
// this works the same in 1.1 and 2.0
//textBox1.Text = System.Text.Encoding.Unicode.GetString(byteData);
// this is where the problem surfaces
textBox1.Text = System.Text.Encoding.ASCII.GetString(byteData);
Now, do exactly the same in VS 2005.
Run both applications, click the button and compare the results in the text box. If you want to go fancy, add a second text box and a second button to VS 2005 project and do the comparison in code as follows:
if (textBox1.Text == textBox2.Text)
MessageBox.Show("Ok. Same.");
else
MessageBox.Show("Not the Same!");
Then, simply copy and paste VS2003’s text box data in text box 2 of VS 2005 project and click the second button to see the results…
