使用sqlbulkcopy 

/// <summary>
/// LaborReport Data Import To Database
/// </summary>
/// <param name="laborReport">laborReport data table</param>
/// <param name="laborReportDetail">laborReportDetail data table</param>
public void LaborReportInsert(DataTable laborReport, DataTable laborReportDetail)
{
using (SqlConnection conn = new SqlConnection(this.Connection))
{
if (conn.State != ConnectionState.Open)
conn.Open(); 
using (SqlBulkCopy sqlBCLaborReport = new SqlBulkCopy(conn))
{
sqlBCLaborReport.BatchSize = laborReport.Rows.Count;
sqlBCLaborReport.BulkCopyTimeout = 60;
sqlBCLaborReport.DestinationTableName = "LaborReport";
sqlBCLaborReport.WriteToServer(laborReport);
}
using (SqlBulkCopy sqlBCLaborReportDetails = new SqlBulkCopy(conn))
{
sqlBCLaborReportDetails.BatchSize = laborReportDetail.Rows.Count;
sqlBCLaborReportDetails.BulkCopyTimeout = 60;
sqlBCLaborReportDetails.DestinationTableName = "LaborReportDetails";
sqlBCLaborReportDetails.WriteToServer(laborReportDetail);
}
if (conn.State != ConnectionState.Closed)
conn.Close();
}
