Determines whether the SqlGeometry instance is well-formed.

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

Syntax

'Declaration

returnValue = instance.STIsValid()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlBoolean STIsValid()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]

SqlBoolean STIsValid()

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STIsValid : unit -> SqlBoolean

public function STIsValid() : SqlBoolean

Rückgabewert

Typ: System.Data.SqlTypes.SqlBoolean
Returns true if a SqlGeometry instance is well-formed, based on its Open Geospatial Consortium (OGC) type. Returns false if a SqlGeometry instance is not well-formed.

Hinweise

The OGC type of a SqlGeometry instance can be determined by invoking STGeometryType.

SQL Server produces only valid SqlGeometry instances, but allows for the storage and retrieval of invalid instances. A valid instance that represents the same point set of any invalid instance can be retrieved using the MakeValid method.
