c# - bulkCopy.WriteToServer 不复制

Question

我正在尝试使用 bulkCopy.WriteToServer() 将数据从我的远程 SQL Server Express 复制到我的本地 SQL Server Express，但是没有数据写入我的本地 SQL Server Express 数据库.

代码立即跳过 WriteToServer() 方法...我不知道它是否在内部失败并且没有显示错误消息

我已阅读 How to duplicate a SQL Server 2000 table programatically using .NET 2.0?我正在使用非常相似的代码。尽管我在远程和本地使用 SQL Server 2008 Express 到 SQL Server 2014 Express:

using (SqlConnection remoteConnection = new SqlConnection(remoteConnectionString))
{
    var query = "SELECT * FROM information_schema.tables WHERE table_type = 'base table'";
    SqlCommand commandGetTables = new SqlCommand(query, remoteConnection);

    try
    {
        remoteConnection.Open();
        SqlDataReader results = commandGetTables.ExecuteReader();

        while (results.Read())
        {
            tables.Add(results.GetString(2));
        }

        results.Close();
    }
    catch (Exception ex)
    {
        //stuff
    }
    finally
    {
        remoteConnection.Close();
    }

    remoteConnection.Open();

    foreach (var table in tables)
    {                    
        // Get data from the source table as a SqlDataReader.
        var commandSourceData = new SqlCommand("SELECT * FROM " + table + ";", remoteConnection);
        var reader = commandSourceData.ExecuteReader();

        using (SqlConnection destinationConnection = new SqlConnection(destinationConnectionString))
        {
            destinationConnection.Open();

            using (var bulkCopy = new SqlBulkCopy(destinationConnection))
            {
                bulkCopy.DestinationTableName = table;

                try
                {
                    // Write from the source to the destination.
                    bulkCopy.WriteToServer(reader);
                }
                catch (Exception ex)
                {
                    //stuff
                }
                finally
                {
                    //stuff removed for this post
                }
            }
        }
    }

    remoteConnection.Close();
}
return true;

我知道这可能会受到 SQL 注入(inject)等的影响，但这个应用程序仅供我使用，而不是这里的问题。

我做错了什么？

编辑

我检查了 reader (var reader = commandSourceData.ExecuteReader();) 的值，它有我所期望的条目，这意味着他可以从远程读取。

Answer 1

bulkCopy.DestinationTableName = table;
bulkCopy.WriteToServer(reader);

这些行是错误的，它应该看起来像这样..

bulkCopy.DestinationTableName = "dbo." + DataTable.TableName; 
bulkCopy.WriteToServer(DataTable);
