The AnnLength structure on the left side of the equality operator.
The AnnLength structure on the right side of the equality operator.
Tests whether two AnnLength structures are equal.
Syntax
public bool operator ==( 
   AnnLength left,
   AnnLength right
)
'Declaration
 
Public Operator =( _
   ByVal left As AnnLength, _
   ByVal right As AnnLength _
) As Boolean
'Usage
 
public bool operator ==( 
   AnnLength left,
   AnnLength right
)
This operator type is not supported by WinRT JavaScript
public:
bool operator ==( 
   AnnLength left,
   AnnLength right
)

Parameters

left
The AnnLength structure on the left side of the equality operator.
right
The AnnLength structure on the right side of the equality operator.

Return Value

This operator returns true if left and right have equal lengths; otherwise false.
Remarks
If the two lengths have different units, comparison will be done after temporarily converted both to a common unit.
Example
 
Public Sub AnnLength_OperatorEquals()
   ' set up a new unit converter with 96 DPI
   Dim converter As AnnUnitConverter = New AnnUnitConverter(96, 96)
   Dim inches As AnnLength = New AnnLength(1.5F, AnnUnit.Inch)
   Dim pixels As AnnLength = New AnnLength(inches.Converted(converter, AnnUnit.Pixel), AnnUnit.Pixel)

   Dim s As String
   ' should say true
   s = String.Format("This should be true: inches == pixels is {0}", AnnLength.op_Equality(inches, pixels))
   MessageBox.Show(s)

   ' should say false
   s = String.Format("This should be false: inches != pixels is {0}", AnnLength.op_Inequality(inches, pixels))
   MessageBox.Show(s)
End Sub
public void AnnLength_OperatorEquals()
{
   // set up a new unit converter with 96 DPI
   AnnUnitConverter converter = new AnnUnitConverter(96, 96);
   AnnLength inches = new AnnLength(1.5F, AnnUnit.Inch);
   AnnLength pixels = new AnnLength(inches.Converted(converter, AnnUnit.Pixel), AnnUnit.Pixel);

   string s;
   // should say true
   s = string.Format("This should be true: inches == pixels is {0}", inches == pixels);
   MessageBox.Show(s);

   // should say false
   s = string.Format("This should be false: inches != pixels is {0}", inches != pixels);
   MessageBox.Show(s);
}
