一維碼生成 c# winform GUI

最近看到同事小紅在做一維碼，感覺挺好玩，于是就在網上找了一個例子來玩玩。

        /// <summary>        /// 生成條碼 Bitmap,自定義條碼高度,自定義文字對齊樣式        /// </summary>        /// <param name="sourceCode"></param>        /// <param name="barCodeHeight"></param>        /// <param name="sf"></param>        /// <returns></returns>        public   Bitmap GetCode39(string sourceCode, int barCodeHeight, StringFormat sf)        {            BarCodeText = sourceCode.ToUpper();            int leftMargin = 5;            int topMargin = 0;            int thickLength = 2;            int narrowLength = 1;            int intSourceLength = sourceCode.Length;            string strEncode = "010010100" ; //添加起始碼“ *”.            var font = new System.Drawing.Font( "Segoe UI", 5);            string AlphaBet = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ-. $/+%*" ;            string[] Code39 =             {                 /* 0 */ "000110100" ,                  /* 1 */ "100100001" ,                  /* 2 */ "001100001" ,                  /* 3 */ "101100000" ,                 /* 4 */ "000110001" ,                  /* 5 */ "100110000" ,                  /* 6 */ "001110000" ,                  /* 7 */ "000100101" ,                 /* 8 */ "100100100" ,                  /* 9 */ "001100100" ,                  /* A */ "100001001" ,                  /* B */ "001001001" ,                 /* C */ "101001000" ,                  /* D */ "000011001" ,                  /* E */ "100011000" ,                  /* F */ "001011000" ,                 /* G */ "000001101" ,                  /* H */ "100001100" ,                  /* I */ "001001100" ,                  /* J */ "000011100" ,                 /* K */ "100000011" ,                  /* L */ "001000011" ,                  /* M */ "101000010" ,                  /* N */ "000010011" ,                 /* O */ "100010010" ,                  /* P */ "001010010" ,                  /* Q */ "000000111" ,                  /* R */ "100000110" ,                 /* S */ "001000110" ,                  /* T */ "000010110" ,                  /* U */ "110000001" ,                  /* V */ "011000001" ,                 /* W */ "111000000" ,                  /* X */ "010010001" ,                  /* Y */ "110010000" ,                  /* Z */ "011010000" ,                 /* - */ "010000101" ,                  /* . */ "110000100" ,                  /*' '*/ "011000100" ,                 /* $ */ "010101000" ,                 /* / */ "010100010" ,                  /* + */ "010001010" ,                  /* % */ "000101010" ,                  /* * */ "010010100"               };            sourceCode = sourceCode.ToUpper();            Bitmap objBitmap = new Bitmap(((thickLength * 3 + narrowLength * 7) * (intSourceLength + 2)) +                                           (leftMargin * 2), barCodeHeight + (topMargin * 2));            Graphics objGraphics = Graphics.FromImage(objBitmap);            objGraphics.FillRectangle( Brushes.White, 0, 0, objBitmap.Width, objBitmap.Height);            for (int i = 0; i < intSourceLength; i++)            {                //非法字符校驗                if (AlphaBet.IndexOf(sourceCode[i]) == -1 || sourceCode[i] == '*' )                {                    objGraphics.DrawString( "Invalid Bar Code", SystemFonts.DefaultFont, Brushes .Red, leftMargin, topMargin);                    return objBitmap;                }                //編碼                strEncode = string.Format("{0}0{1}" , strEncode,                Code39[AlphaBet.IndexOf(sourceCode[i])]);            }            strEncode = string.Format("{0}0010010100" , strEncode); //添加結束碼“*”            int intEncodeLength = strEncode.Length;            int intBarWidth;            for (int i = 0; i < intEncodeLength; i++) //繪制 Code39 barcode            {                intBarWidth = strEncode[i] == '1' ? thickLength : narrowLength;                objGraphics.FillRectangle(i % 2 == 0 ?

好了，如果有興趣的同學就可以去看看怎么實現自己的想要的一維碼了。
