When(IFilterItem, IElement)

Adds a branch to a searched case expression.

public Case When(IFilterItem condition, IElement result)

Parameters

condition IFilterItem

The condition selecting this branch, such as a Criterion<T> or a nested Filter.

result IElement

The value produced when the condition is true.

Returns

Case

This case expression, for method chaining.

Remarks

Branches are evaluated in the order they are added and the first true condition wins, so add the most specific condition first.

Exceptions

InvalidOperationException

Thrown when this is a simple case expression, which takes values rather than conditions.

When(IElement, IElement)

Adds a branch to a simple case expression.

public Case When(IElement value, IElement result)

Parameters

value IElement

The value compared against the case expression's operand.

result IElement

The value produced when the operand equals this branch value.

Returns

Case

This case expression, for method chaining.

Remarks

Branches are evaluated in the order they are added and the first match wins, which is how ties between equal values are broken.

Exceptions

InvalidOperationException

Thrown when this is a searched case expression, which takes conditions rather than values.
