    'Declaration
     
    Public Property FocalLength As Nullable(Of ImGearRationalUInt)
    'Usage
     
    Dim instance As ImGearEXIFMetadata
    Dim value As Nullable(Of ImGearRationalUInt)
     
    instance.FocalLength = value
     
    value = instance.FocalLength
    public Nullable<ImGearRationalUInt> FocalLength {get; set;}
    public: __property Nullable<ImGearRationalUInt> get_FocalLength();
    public: __property void set_FocalLength( 
       Nullable<ImGearRationalUInt> value
    );
    public:
    property Nullable<ImGearRationalUInt> FocalLength {
       Nullable<ImGearRationalUInt> get();
       void set (    Nullable<ImGearRationalUInt> value);
    }

    Property Value

    Nullable (boxed) ImageGear.Core.ImGearRationalUInt structure value.
    Remarks
    This property accesses the FocalLength tag. The tag specifies the actual focal length of the lens, in mm. Conversion is not made to the focal length of a 35 mm film camera.

    Get accessor returns the tag value if the tag is present in the metadata tree, or null otherwise.

    Set accessor replaces the current tag value if the tag is present in the metadata tree, adds the tag if it was not present, or deletes the tag if a null value is passed.

    See the EXIF 2.2 specification for tag usage details.
