Public Shared Function Deserialize ( _
bytes As SqlBytes _
) As SqlGeometry
'用途
Dim bytes As SqlBytes
Dim returnValue As SqlGeometry
returnValue = SqlGeometry.Deserialize(bytes)
public static SqlGeometry Deserialize(
SqlBytes bytes
)
public:
static SqlGeometry^ Deserialize(
SqlBytes^ bytes
)
static member Deserialize :
bytes:SqlBytes -> SqlGeometry
public static function Deserialize(
bytes : SqlBytes
) : SqlGeometry
參數
- bytes
型別：System.Data.SqlTypes.SqlBytes
A SqlBytes that specifies the spatial data being sent over the network.
傳回值
型別：Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry instance that represents the constructed geometry object being sent over the network.
備註
This can be used for reading bytes sent from the server through SqlDataReader. Useful for sending spatial data over the network in conjunction with Serialize().
範例
using (SqlConnection conn = new SqlConnection("..."))
{
SqlCommand cmd = new SqlCommand("SELECT [SpatialData] FROM [SpatialTable]", conn);
conn.Open();
using (SqlDataReader rdr = cmd.ExecuteReader())
{
while (rdr.Read())
{
SqlGeometry g = SqlGeometry.Deserialize(reader.GetSqlBytes(0).Stream));
// do some spatial work
}
}
