public SelectClause(IEnumerable<string> propertyPaths)

Parameters

The property paths to select, as they were written.

public IEnumerable<string> PropertyPaths { get; }

Property Value

IEnumerable<string>

Methods

The clause, or null if propertyPaths was null.

Validate(Type)

Resolve every path against the entity type being queried, filling in Properties.

public void Validate(Type entityType)

Parameters

entityType Type

The type the query returns.

Exceptions

A path does not name a property of that type.
