Condition

A Condition is a single filter predicate — one field, one operator, and zero or more operand values. It is the smallest building block of every filter, segment, or summary you send.

Properties

Property	Type	Description
`Sort`	`int`	Evaluation order within a `ConditionGroup` (must be unique among siblings).
`Field`	`string?`	Property path on the entity (supports dot notation, e.g. `"Order.Customer.Name"`).
`DataType`	`DataType`	Logical data type for value parsing.
`Operator`	`Operator`	Comparison operator.
`Values`	`List<object>`	Operand values (count depends on operator). Accepts raw JSON types — strings, numbers, booleans — and is normalized per `DataType`. See Value Coercion below.

C# example

var condition = new Condition
{
    Sort = 1,
    Field = "Name",
    DataType = DataType.Text,
    Operator = Operator.IContains,
    Values = new List<object> { "john" }
};

JSON example

{
  "sort": 1,
  "field": "Name",
  "dataType": "Text",
  "operator": "IContains",
  "values": ["john"]
}

Value coercion

Values is List<object> so the front-end can send heterogeneous JSON shapes without quoting every primitive:

{
  "Field": "Price",
  "DataType": "Number",
  "Operator": "Between",
  "Values": [0, 1.569]
}

{
  "Field": "IsActive",
  "DataType": "Boolean",
  "Operator": "Equal",
  "Values": [false]
}

The library normalizes every element before validation/build:

Incoming runtime type	Normalized form
`string`	as-is
`bool`	`"true"` / `"false"` (lowercase)
`JsonElement` (System.Text.Json)	unwrapped by `ValueKind` (`String` → text, `Number` → raw JSON token, `True`/`False` → lowercase)
numeric / `IFormattable`	`InvariantCulture` formatting
anything else (`JValue`, etc.)	`value.ToString()`
`null`	`string.Empty`

Backward compatibility

Callers previously sending ["abc"] (quoted strings) keep working unchanged — strings deserialize into the List<object> as string elements. C# callers that previously used Values = new List<string> {...} must switch to new List<object> {...} (or .Cast<object>().ToList()).
