SqlGeometry.Deserialize Method (SqlBytes)


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)

public static SqlGeometry Deserialize(
	SqlBytes bytes


Type: System.Data.SqlTypes.SqlBytes

A SqlBytes that specifies the spatial data being sent over the network.

Return Value

Type: Microsoft.SqlServer.Types.SqlGeometry

A SqlGeometry instance that represents the constructed geometry object being sent over the network.

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().

using (SqlConnection conn = new SqlConnection("..."))
      SqlCommand cmd = new SqlCommand("SELECT [SpatialData] FROM [SpatialTable]", conn);
      using (SqlDataReader rdr = cmd.ExecuteReader())
            while (rdr.Read())
                  SqlGeometry g = SqlGeometry.Deserialize(reader.GetSqlBytes(0).Stream));
                                                // do some spatial work
