Methods

BatchGetDocuments(BatchGetDocumentsRequest, CallSettings)

public virtual FirestoreClient.BatchGetDocumentsStream BatchGetDocuments(BatchGetDocumentsRequest request, CallSettings callSettings = null)

Gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

Parameters
Name Description
request BatchGetDocumentsRequest

The request object containing all of the parameters for the API call.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
FirestoreClientBatchGetDocumentsStream

The server stream.
Example 
// Create client
FirestoreClient firestoreClient = FirestoreClient.Create();
// Initialize request argument(s)
BatchGetDocumentsRequest request = new BatchGetDocumentsRequest
{
    Database = "",
    Documents = { "", },
    Mask = new DocumentMask(),
    Transaction = ByteString.Empty,
};
// Make the request, returning a streaming response
using FirestoreClient.BatchGetDocumentsStream response = firestoreClient.BatchGetDocuments(request);

// Read streaming responses from server until complete
// Note that C# 8 code can use await foreach
AsyncResponseStream<BatchGetDocumentsResponse> responseStream = response.GetResponseStream();
while (await responseStream.MoveNextAsync())
{
    BatchGetDocumentsResponse responseItem = responseStream.Current;
    // Do something with streamed response
}
// The response stream has completed

BatchWrite(BatchWriteRequest, CallSettings)

public virtual BatchWriteResponse BatchWrite(BatchWriteRequest request, CallSettings callSettings = null)
