读取点阵字库
本次所用字库为横向取模的16*16点阵字库，ucdos自带。
源字库文件放到资源文件中并嵌入exe，应用时只复制exe到用户处，双击即可运行并提取字库，不用再复制ASC16及HZK16文件。
可将此功能做成dll，方便别的项目调用。
建立好项目后建立一个资源文件，然后添加文件，将ASC16及HZK16文件添加到资源文件中。
读取资源文件中的两个字库文件到文件流:
ResourceManager resource = new ResourceManager(typeof(Resource1));//About为资源文件名（没有扩展名）
byte[] bitASC16 = resource.GetObject("ASC16") as byte[];//图片资源名
byte[] bitHZK16 = resource.GetObject("HZK16") as byte[];//图片资源名
//将byte[]写入FileStream
FileStream fsAsc16 = new FileStream("sASC16", FileMode.OpenOrCreate);
fsAsc16.Write(bitASC16, 0, bitASC16.Length);
FileStream fsHzk16 = new FileStream("sHZK16", FileMode.OpenOrCreate);
fsHzk16.Write(bitHZK16, 0, bitHZK16.Length);
具体实现代码（textBox1.Text为要取字模的字符，半角或全角，数字、字母、汉字；textBox2.Text为取到的十六进制的16*16点阵字库）：
private void btnGet_Click(object sender, EventArgs e)
{
ResourceManager resource = new ResourceManager(typeof(Resource1));//Resource1为资源文件名（没有扩展名）
byte[] bitASC16 = resource.GetObject("ASC16") as byte[];//添加到资源文件中的文件名
byte[] bitHZK16 = resource.GetObject("HZK16") as byte[];//添加到资源文件中的文件名
textBox2.Text = "";
int cnt = 16;
string message = textBox1.Text;
FileStream fsAsc16 = new FileStream("sASC16", FileMode.OpenOrCreate);
fsAsc16.Write(bitASC16, 0, bitASC16.Length);
FileStream fsHzk16 = new FileStream("sHZK16", FileMode.OpenOrCreate);
fsHzk16.Write(bitHZK16, 0, bitHZK16.Length);
//字库不放入资源文件，单独放于可执行文件同级目录下
//FileStream fsAsc16 = new FileStream("ASC16", FileMode.Open); //将"ASC16"字库文件读入文件流
//FileStream fsHzk16 = new FileStream("HZK16", FileMode.Open); //将"HZK16"字库文件读入文件流
for (int index = 0; index < message.Length; index++)
{
string s = message.Substring(index, 1);
if (Convert.ToChar(s) < 256) //判断是否为中文，小于256为字符
{
byte[] bMsg = new byte[16];
int offset = cnt * (byte)(s[0]);
fsAsc16.Seek(offset, SeekOrigin.Begin);
fsAsc16.Read(bMsg, 0, 16);
for (int i = 0; i < bMsg.Length; i++)
{
textBox2.Text += bMsg[i].ToString("X2");
}
}
else
{
byte[] bMsg = new byte[32];
byte[] bytes = Encoding.GetEncoding("GB2312").GetBytes(s.ToCharArray());
int offset = 32 * (94 * (bytes[0] - 0xA1) + bytes[1] - 0xA1);
fsHzk16.Seek(offset, SeekOrigin.Begin);
fsHzk16.Read(bMsg, 0, 32);
for (int i = 0; i < bMsg.Length; i++)
{
textBox2.Text += bMsg[i].ToString("X2");
}
}
}
fsAsc16.Close();
fsHzk16.Close();
}
