Méthode SqlGeometry.Deserialize
Returns a constructed SqlGeometry from an internal SQL Server format for spatial data.

Assembly : Microsoft.SqlServer.Types (en Microsoft.SqlServer.Types.dll)
Syntaxe
'Déclaration
Public Shared Function Deserialize ( _
bytes As SqlBytes _
) As SqlGeometry
'Utilisation
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
Paramètres
- bytes
Type : System.Data.SqlTypes.SqlBytes
A SqlBytes that specifies the spatial data being sent over the network.
Valeur de retour
Type : Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry instance that represents the constructed geometry object being sent over the network.
Notes
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().
Exemples
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
}
}
