c# datatable批量插入数据库，服务器上的数据库同步，不用写sql语句，简单迅速

tableName是表的表名。

public void insertSql(string tableName)
{
SqlConnection conS = new SqlConnection(connectStringServer);
SqlConnection conC = new SqlConnection(connectStringClient);
conS.Open();
conC.Open();

string sql = "select * from " + tableName;
SqlCommand com = new SqlCommand(sql, conS);
SqlDataAdapter sa = new SqlDataAdapter(com);
DataSet ds = new DataSet();
sa.Fill(ds);

//先删除本地数据库在插入
string sqlBendi = "delete from " + tableName;
SqlCommand comBendi = new SqlCommand(sqlBendi, conC);
comBendi.ExecuteNonQuery();

SqlTransaction sqlbulkTransaction = conC.BeginTransaction();
SqlBulkCopy sqlbulkcopy = new SqlBulkCopy(conC, SqlBulkCopyOptions.CheckConstraints, sqlbulkTransaction);
sqlbulkcopy.DestinationTableName = tableName;//
sqlbulkcopy.WriteToServer(ds.Tables[0]);
sqlbulkTransaction.Commit();

conC.Close();
conS.Close();
}
