导入excel到sql c＃

我一直在试图导入到我的SQL数据库的Excel表。 我试过这个例子：

void importdata(string excelfilepath) { //declare variables - edit these based on your particular situation string ssqltable = "tTableExcel"; // make sure your sheet name is correct, here sheet name is sheet1, so you can change your sheet name if have string myexceldataquery = "select student,rollno,course from [sheet1$]"; try { //create our connection strings string sexcelconnectionstring = @"provider=microsoft.jet.oledb.4.0;data source=" + excelfilepath + ";extended properties=" + "\"excel 8.0;hdr=yes;\""; string ssqlconnectionstring = "server=mydatabaseservername;userid=dbuserid;password=dbuserpassword;database=databasename;connection reset=false"; string sclearsql = "delete from " + ssqltable; SqlConnection sqlconn = new SqlConnection(ssqlconnectionstring); SqlCommand sqlcmd = new SqlCommand(sclearsql, sqlconn); sqlconn.Open(); sqlcmd.ExecuteNonQuery(); sqlconn.Close(); //series of commands to bulk copy data from the excel file into our sql table OleDbConnection oledbconn = new OleDbConnection(sexcelconnectionstring); OleDbCommand oledbcmd = new OleDbCommand(myexceldataquery, oledbconn); oledbconn.Open(); OleDbDataReader dr = oledbcmd.ExecuteReader(); SqlBulkCopy bulkcopy = new SqlBulkCopy(ssqlconnectionstring); bulkcopy.DestinationTableName = ssqltable; while (dr.Read()) { bulkcopy.WriteToServer(dr); } oledbconn.Close(); } catch (Exception ex) { //handle exception } } 

我的编程不是很好，我不能使它工作。 SQL连接没有任何问题（在运行程序后db被清除）。 但是我无法获得任何信息到数据库中。 我的excel文件被称为test.xlsx，存储在D：\ Users \ Haners中。 我的数据库tabe被称为testing。 我怎样才能让我的程序导入excel文件中的信息到数据库？

前面的代码：

  SqlBulkCopy bulkcopy = new SqlBulkCopy(ssqlconnectionstring); bulkcopy.DestinationTableName = ssqltable; while (dr.Read()) { bulkcopy.WriteToServer(dr); } 

新代码：

  SqlBulkCopy bulkcopy = new SqlBulkCopy(ssqlconnectionstring); bulkcopy.DestinationTableName = ssqltable; bulkcopy.BatchSize=100; bulkcopy.WriteToServer(dr); 

希望这有助于解决您的问题。 快乐的编码。 干杯
