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