C# RichTextBox中替换乱码，该怎么解决呢？

言多必失 2012-07-01 08:10:39

RichTextBox打开RTF内容，比如现在要把 #Name# 替换成 "武汉大学"，#Name# 字体有颜色的，就是Word中编辑的了。

替换后乱码，我开始以为是编码问题，我写了个测试还是不行,要替换Rtf 的，因为这样能保留样式，要是用richTextBox1.Text的话，就是变的特别难看。求指点下。

代码如下



    int i = 0;

        private void button4_Click(object sender, EventArgs e)

        {

            LoadData();//重新打开Rtf

          

            string text = "武汉大学";

            string code = "";

            System.Text.Encoding gb2312 = System.Text.Encoding.GetEncoding("gb2312");

            byte[] gb = gb2312.GetBytes(text);

            switch (i % 10)

            {

                case 0:

                    code = Encoding.Default.GetString(gb);

                    break;

                case 1:

                    code = Encoding.ASCII.GetString(gb);

                    break;

                case 2:

                    code = Encoding.Unicode.GetString(gb);

                    break;

                case 3:

                    code = Encoding.UTF32.GetString(gb);

                    break;

                case 4:

                    code = Encoding.UTF7.GetString(gb);

                    break;

                case 5:

                    code = Encoding.UTF8.GetString(gb);

                    break;

                case 6:

                    code = Encoding.Unicode.GetString(gb);

                    break;

                case 7:

                    code = System.Text.Encoding.GetEncoding("gb2312").GetString(gb); ;



                    break;

                default:

                    code = Encoding.BigEndianUnicode.GetString(gb);

                    break;

            }

            i++;

            this.Text = i.ToString();

            richTextBox1.Rtf = richTextBox1.Rtf.Replace("#Name#", code);

        }
