復制代碼 代碼如下:
private void AddManyData_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Excel文件|*.xls";
if ((bool)openFileDialog.ShowDialog())
{
FileInfo fileInfo = new FileInfo(openFileDialog.FileName);
string filePath = fileInfo.FullName;
string connExcel = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filePath + ";Extended Properties=Excel 8.0";
using (OleDbConnection oleDbConn = new OleDbConnection(connExcel))
{
oleDbConn.Open();
//獲取excel表
DataTable dt = oleDbConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
//獲取Excel表的表名
string tableName = dt.Rows[0][2].ToString().Trim();
//去掉空格
tableName = "[" + tableName.Replace("'", "") + "]";
//利用SQL語句從Excel文件裡獲取數據
string query = @"SELECT 學號,姓名,公益勞動,電子工藝實習,操作系統 ,計算機組成,數值分析,網絡設備與集成,動態網站開發實驗周,動態網站開發,均分,排名 FROM "; + tableName;
DataSet dataSet = new DataSet();
using (OleDbCommand oleDbcomm = oleDbConn.CreateCommand())
{
oleDbcomm.CommandText = query;
OleDbDataAdapter oleAdapter = new OleDbDataAdapter(oleDbcomm);
oleAdapter.Fill(dataSet);
}
string connStr = "Data Source=HESHUHUA-PC;Initial Catalog=RSMSystem;Integrated Security=True";
//利用SqlBulkCopy批量插入數據
using (SqlBulkCopy sqlbc = new SqlBulkCopy(connStr))
{
sqlbc.DestinationTableName = "T_StuScore";
// sqlbc.ColumnMappings.Add("學號", "StuNum"),第一個參數對應數據庫中的列名,
//第二個參數對應數據庫中相應表的列名
sqlbc.ColumnMappings.Add("學號", "StuNum");
sqlbc.ColumnMappings.Add("姓名", "StuName");
sqlbc.ColumnMappings.Add("公益勞動", "Activity");
sqlbc.ColumnMappings.Add("電子工藝實習", "ElecAct");
