写文件

注：目前我只用到了将信息写入TXT文件中，其他文件类型不知道能不能用~  

       /// <summary>
        /// 写文件
        /// </summary>
        /// <param name="filename"></param>
        public static void WriteFile(string filename, string values)
        {
            string path = @filename;

            FileStream fs = new FileStream(path, FileMode.Append,

                                                         FileAccess.Write, FileShare.ReadWrite);

            fs.Lock(0, fs.Length);
            byte[] every = new UTF8Encoding(true).GetBytes(values);
            fs.Write(every, 0, every.Length);
            fs.Close();
            every.Initialize();
            values = null;
        }

调用：

    string FileName = Application.StartupPath + "//ImpErroLog//tets.txt";(winform中的程序，将写在与可执行同级目下！)

    WriteFile(fileName, "导入文件中的字段和选择要导入的字段不一致！"+  Environment.NewLine);
