C# Datatable导出Excel方法

C# 导出Excel方法  先引用下System.IO;System.data;

具体函数如下：

        public static bool ExportCSV(DataTable dt, string fileNmae)
        {
            bool Msg = false;
            string con = "";
            foreach (DataColumn dc in dt.Columns)
            {
                con += dc.ColumnName + ",";
            }
            con = con.TrimEnd(',') + Environment.NewLine;

            for (int i = 0; i < dt.Rows.Count; i++)
            {
                for (int j = 0; j < dt.Columns.Count; j++)
                {
                    con += dt.Rows[i][j].ToString().Replace("
", " ").Replace("
", " ").Replace(",", "，") + ",";
                }
                con = con.TrimEnd(',') + Environment.NewLine;
            }
            try
            {
                FileStream fs = new FileStream(fileNmae, FileMode.Create);
                byte[] b = Encoding.GetEncoding("gb2312").GetBytes(con);
                fs.Write(b, 0, b.Length);
                fs.Close();
                Msg = true;
            }
            catch (Exception ex)
            {
                Log.WriteLog(LogFile.Error, ex.Message);
            }
            return Msg;
        }
