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：

 1         public static bool ExportCSV(DataTable dt, string fileNmae)

 2         {

 3             bool Msg = false;

 4             string con = "";

 5             foreach (DataColumn dc in dt.Columns)

 6             {

 7                 con += dc.ColumnName + ",";

 8             }

 9             con = con.TrimEnd(‘,‘) + Environment.NewLine;

10

11             for (int i = 0; i < dt.Rows.Count; i++)

12             {

13                 for (int j = 0; j < dt.Columns.Count; j++)

14                 {

15                     con += dt.Rows[i][j].ToString().Replace("\n", " ").Replace("\r\n", " ").Replace(",", "，") + ",";

16                 }

17                 con = con.TrimEnd(‘,‘) + Environment.NewLine;

18             }

19             try

20             {

21                 FileStream fs = new FileStream(fileNmae, FileMode.Create);

22                 byte[] b = Encoding.GetEncoding("gb2312").GetBytes(con);

23                 fs.Write(b, 0, b.Length);

24                 fs.Close();

25                 Msg = true;

26             }

27             catch (Exception ex)

28             {

29                 Log.WriteLog(LogFile.Error, ex.Message);

30             }

31             return Msg;

32         }
