SqlGeometry.Deserialize-Methode

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

Namespace:  Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)

Syntax

'Declaration
Public Shared Function Deserialize ( _
    bytes As SqlBytes _
) As SqlGeometry
'Usage
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

Parameter

Rückgabewert

Typ: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry instance that represents the constructed geometry object being sent over the network.

Hinweise

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().

Beispiele

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

            }
}
