public ComparisonExpression(ComparisonOperator @operator, QueryExpression left, QueryExpression right)

Parameters

operator ComparisonOperator

left QueryExpression

right QueryExpression

Properties

Left

The left-hand operand, which can be a function or a field chain. Chain format: an optional list of to-one relationships, followed by an attribute. When comparing equality with null, the chain may also end in a to-one relationship.

public QueryExpression Left { get; }

Property Value

QueryExpression

Operator

The operator used to compare Left and Right.

public ComparisonOperator Operator { get; }

Property Value

ComparisonOperator

Right

The right-hand operand, which can be a function, a field chain, a constant, or null (if the type of Left is nullable). Chain format: an optional list of to-one relationships, followed by an attribute.

public QueryExpression Right { get; }

Property Value

QueryExpression
