Google.Cloud.BigQuery.DataTransfer.V1

Google.Cloud.BigQuery.DataTransfer.V1 is a.NET client library for the Google BigQuery Data Transfer API.

Note: This documentation is for version 3.4.0 of the library. Some samples may not work with other versions.

Installation

Install the Google.Cloud.BigQuery.DataTransfer.V1 package from NuGet. Add it to your project in the normal way (for example by right-clicking on the project in Visual Studio and choosing "Manage NuGet Packages...").

Authentication

When running on Google Cloud Platform, no action needs to be taken to authenticate.

Otherwise, the simplest way of authenticating your API calls is to download a service account JSON file then set the GOOGLE_APPLICATION_CREDENTIALS environment variable to refer to it. The credentials will automatically be used to authenticate. See the Getting Started With Authentication guide for more details.

Getting started

All operations are performed through DataTransferServiceClient.

Create a client instance by calling the static Create or CreateAsync methods. Alternatively, use the builder class associated with each client class (e.g. DataTransferServiceClientBuilder for DataTransferServiceClient) as an easy way of specifying custom credentials, settings, or a custom endpoint. Clients are thread-safe, and we recommend using a single instance across your entire application unless you have a particular need to configure multiple client objects separately.

Sample code

List all data sources

DataTransferServiceClient client = DataTransferServiceClient.Create();
ProjectName parent = ProjectName.FromProject(projectId);
PagedEnumerable<ListDataSourcesResponse, DataSource> sources = client.ListDataSources(parent);
foreach (DataSource source in sources)
{
    Console.WriteLine($"{source.DataSourceId}: {source.DisplayName} ({source.Description})");
}
