C# 代码转换

Question

麻烦大大们帮忙转下这个
string con = this.textBox1.Text;
            Stream myStream;
            byte[] File = new Encode().HexToByte(con);            SaveFileDialog sf = new SaveFileDialog();
            sf.Filter = "Zip文件|*.zip";
            sf.FilterIndex = 1;
            sf.RestoreDirectory = true;
            if (sf.ShowDialog() == DialogResult.OK)
            {
                if ((myStream = sf.OpenFile()) != null)
                {
                    BinaryWriter bw = new BinaryWriter(myStream);
                    bw.Write(File);
                    myStream.Close();
                    MessageBox.Show("成功");
                }
                else
                {
                    MessageBox.Show("失败");
                }
            }
            else
            {
                MessageBox.Show("取消");
            }---------------------------
不用SaveFileDialog 来直接保存 为文件 我用FileStream fs = new FileStream(@"aa.txt",FileMode.Create);
结果没有反应谢谢了

Answer 1

同时确保路径是否正确   
byte[] array = new Encode().HexToByte(con);
            fs = new FileStream(path, FileMode.Create, FileAccess.Write);
            fs.Write(array, 0, array.Length);
            fs.Flush();

aa.txt表示和你的exe在同一目录下，而且FileStream创建的文件是否可写
