Declaration
public NotEqualExpression(RadExpression left, RadExpression right)
Parameters
RadExpression left

The left.
RadExpression right

The right.

Property Value
OperatorInfo

The operator info as OperatorInfo.
Overrides

Methods

CompareBooleanExpressions(BooleanExpression, BooleanExpression)

Compares two boolean expressions and returns true if they have different values using XOR logic.

Declaration
protected override bool CompareBooleanExpressions(BooleanExpression left, BooleanExpression right)
Parameters
BooleanExpression left

The left.
BooleanExpression right

The right.
Returns
System.Boolean

Boolean result.
Overrides

CompareDifferentTypeExpressions(ConstantExpression, ConstantExpression)

Compares expressions of different types and returns true unless comparing equivalent values like zero and empty, applying special rules for boolean and empty operands.

Declaration
protected override bool CompareDifferentTypeExpressions(ConstantExpression leftOperandValue, ConstantExpression rightOperandValue)
Parameters
ConstantExpression leftOperandValue

The left operand value.
ConstantExpression rightOperandValue

The right operand value.
Returns
System.Boolean

Boolean result.
Overrides

CompareEmptyExpressions(EmptyExpression, EmptyExpression)

Compares two empty expressions and always returns false since empty values are equal.

Declaration
protected override bool CompareEmptyExpressions(EmptyExpression left, EmptyExpression right)
Parameters
EmptyExpression left

The left operand value.
EmptyExpression right

The right operand value.
Returns
System.Boolean

Boolean result.
Overrides

CompareNumberExpressions(NumberExpression, NumberExpression)

Compares two number expressions and returns true if the values are not equal.

Declaration
protected override bool CompareNumberExpressions(NumberExpression left, NumberExpression right)
Parameters
NumberExpression left

The left.
NumberExpression right

The right.
Returns
System.Boolean

Boolean result.
Overrides

CompareStringExpressions(StringExpression, StringExpression)

Compares two string expressions and returns true if they are not equal using case-insensitive comparison.

Declaration
protected override bool CompareStringExpressions(StringExpression left, StringExpression right)
Parameters
StringExpression left

The left.
StringExpression right

The right.
Returns
System.Boolean

Boolean result.
Overrides
