Add(String, SpannerDbType, Object)
public SpannerStruct.Field Add(string name, SpannerDbType type, object value)Adds a new field to the struct with the given name, type and value.
| Parameters | |
|---|---|
| Name | Description |
name | StringThe name of the field. May be null, and does not need to be unique within the struct. If the value is null, the SpannerStruct.Field value added will have an empty string for the name. |
type | SpannerDbTypeThe type of the field. Must not be null. |
value | ObjectThe value of the field. May be null. |
| Returns | |

GetSpannerDbType()
public SpannerDbType GetSpannerDbType()Returns the full schema of this struct as a SpannerDbType.
| Returns | |
|---|---|
| Type | Description |
SpannerDbType | The SpannerDbType representing the schema of this struct. |
The returned object reflects the current fields in the struct. If more fields are added later, those changes will not be visible via the returned value. Instead, this method should be called again obtain the up-to-date schema.
