将一个表中的多行保存在sqlserver的一个连接中

将每个问题Id及其选择答案保存在数据表中，然后将数据表插入到 SQL 表中，如下所示：

DataTable dataTable = null; // your data needs to be here
        try
        {
            ConnectionStringSettings mConString = ConfigurationManager.ConnectionStrings["SiteSqlServer"];

            // Optional truncating old table
            using (SqlConnection connection = new SqlConnection(mConString.ConnectionString))
            {
                connection.Open();
                // Delete old entries
                SqlCommand truncate = new SqlCommand("TRUNCATE TABLE MYTABLE", connection);
                truncate.ExecuteNonQuery();
            }

            SqlBulkCopy bulkCopy = new SqlBulkCopy(mConString.ConnectionString, SqlBulkCopyOptions.TableLock)
                                          {
                                              DestinationTableName = "dbo.MYTABLE",
                                              BatchSize = 100, //set your required size
                                              BulkCopyTimeout = 360
                                          };
            bulkCopy.WriteToServer(dataTable);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }
