string

JobIdPrefix

public string JobIdPrefix { get; set; }

If specified, use this prefix when generating a job ID. (Job IDs are always generated client-side by this library, to allow insertion to be retried where necessary.) It is an error to set both this property and JobId.

Property Value

Labels

public IDictionary<string, string> Labels { get; set; }

Label keys and values can be no longer than 63 characters, can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. If a label value is 

null
, it won't be added to the job's labels. A label value can be Empty. Label keys must start with a letter.

Example 
IDictionary<string, string> labels = new Dictionary<string, string>()
{
    {"label-key", "label-value" }
};

BigQueryClient client = BigQueryClient.Create(projectId);
BigQueryTable table = client.GetTable(projectId, datasetId, tableId);
string destinationUri = $"gs://{bucketName}/{objectName}";

// Just a couple examples of jobs marked with labels:
// (These jobs will most certainly be created somewhere else.)
// Running a query on a given table.
BigQueryJob oneLabeledJob = client.CreateQueryJob(
    $"SELECT * FROM {table}", null,
    new QueryOptions { Labels = labels });
// Extracting data from a table to GCS.
BigQueryJob anotherLabeledJob = client.CreateExtractJob(
    projectId, datasetId, tableId, destinationUri,
    new CreateExtractJobOptions { Labels = labels });

// Find jobs marked with a certain label.
KeyValuePair<string, string> labelToBeFound = labels.First();
        // Specify full projection to make sure that
        // label information, if it exists, is returned for listed jobs.
ListJobsOptions options = new ListJobsOptions { Projection = ProjectionEnum.Full };
List <BigQueryJob> jobs = client
    .ListJobs(options)
    .Where(job => job.Resource.Configuration.Labels?.Contains(labelToBeFound) ?? false)
    .Take(2)
    .ToList();
foreach (BigQueryJob job in jobs)
{
    Console.WriteLine(job.Reference.JobId);
}
