Npgsql - BulkCopy from ConcurrentQueue<T> - bulkinsert

Question

Let's say I have a method like this:
public async Task BulkCopy(ConcurrentQueue<Model> modelQueue, string connectionString)
{
while(modelQueue.IsEmpty == false)
{
try
{
using(NpgsqlConnection connection = new NpgsqlConnection(connectionString))
{
await connection.OpenAsync();
using(var writer = connection.BeginBinaryImport("COPY myTable (Id,Name,Something,SomethingElse)"))
{
// Is this what I'm supposed to do?
foreach(Model item in modelQueue)
{
writer.WriteRow(item);
}
}
}
}
}
}
Model has properties Guid Id, string Name, string Something, string SomethingElse(just like the table).
Can I use WriteRow() and pass in an entire object? Is this implementation way to go or I am doing it wrong?

The answer to this is pretty simple, since ConcurrentQueue implements IEnumerable all I had to do is run through the queue and write the data.
public async Task BulkCopy(ConcurrentQueue<Model> modelQueue, string connectionString)
{
while(modelQueue.IsEmpty == false)
{
try
{
using(NpgsqlConnection connection = new NpgsqlConnection(connectionString))
{
await connection.OpenAsync();
using(var writer = connection.BeginBinaryImport("COPY myTable (Id,Name,Something,SomethingElse) FROM STDIN (FORMAT BINARY)"))
{
foreach(Model item in modelQueue)
{
writer.StartRow();
writer.Write(item.Id, NpgsqlTypes.NpgsqlDbType.Uuid);
writer.Write(item.Name);
writer.Write(item.Something);
writer.Write(item.SomethingElse);
}
}
}
}
}
}
This seems to do the job. The time needed for 30000 records is average 540ms.
