string MyString = "西門逸凡的blog--2010";

 

  ASCIIEncoding MyData = new ASCIIEncoding();

  byte[] MyBytes = MyData.GetBytes(MyString);

  //MyLength 為字串的實際長度

  int MyLength= 0;

  for (int i = 0; i <= MyBytes.Length - 1; i++)

  {

  //判斷是否為漢字或全腳符號

  if (MyBytes[i] == 63)

  {

  MyLength++;

  }

  MyLength++;

  }

  String MyInfo ="“"+MyString+ "”共有"+MyString.Length.ToString()+"個字元,";

  MyInfo += "實際長度為" + MyLength.ToString() + "位元組。";

  MessageBox.Show(MyInfo, "資訊提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
