## Constructors

### WriteStream()

    public WriteStream()

### WriteStream(WriteStream)

    public WriteStream(WriteStream other)

| **Parameter** ||
|---|---|
| **Name** | **Description** |
| `other` | `https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.BigQuery.Storage.V1/latest/Google.Cloud.BigQuery.Storage.V1.WriteStream` |

## Properties

### CommitTime

    public Timestamp CommitTime { get; set; }

Output only. Commit time of the stream.
If a stream is of `COMMITTED` type, then it will have a commit_time same as
`create_time`. If the stream is of `PENDING` type, empty commit_time
means it is not committed.

| **Property Value** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/dotnet/docs/reference/Google.Protobuf/latest/Google.Protobuf.WellKnownTypes.Timestamp.html` |   |

### CreateTime

    public Timestamp CreateTime { get; set; }

Output only. Create time of the stream. For the _default stream, this is
the creation_time of the table.

| **Property Value** ||
|---|---|
| **Type** | **Description** |
| `https://cloud.google.com/dotnet/docs/reference/Google.Protobuf/latest/Google.Protobuf.WellKnownTypes.Timestamp.html` |   |

### Location

    public string Location { get; set; }

Output only. The geographic location where the stream's dataset resides.
See <https://cloud.google.com/bigquery/docs/locations> for supported
locations.

| **Property Value** ||
|---|---|

### TableSchema

    public TableSchema TableSchema { get; set; }

Output only. The schema of the destination table. It is only returned in
`CreateWriteStream` response. Caller should generate data that's
compatible with this schema to send in initial `AppendRowsRequest`.
The table schema could go out of date during the life time of the stream.

| **Property Value** ||
|---|---|
