Properties

AllowNewToEvaluateAnyType

Allows the New() keyword to evaluate any available Type.

Default value is false.

Declaration

public bool AllowNewToEvaluateAnyType { get; set; }

AreContextKeywordsEnabled

Determines if the context keywords (it, parent, and root) are valid and usable inside a Dynamic Linq string expression.
Does not affect the usability of the equivalent context symbols ($, ^ and ~).

Default value is false.

Declaration

public bool AreContextKeywordsEnabled { get; set; }

Property Value

Boolean

CustomTypeProvider

Gets or sets the IDynamicLinkCustomTypeProvider.

public IDynamicLinkCustomTypeProvider CustomTypeProvider { get; set; }

Property Value

Type	Description
IDynamicLinkCustomTypeProvider

DateTimeIsParsedAsUTC

By default DateTime (like 'Fri, 10 May 2019 11:03:17 GMT') is parsed as local time. Use this flag to parse all DateTime strings as UTC.

Default value is false.

Declaration

public bool DateTimeIsParsedAsUTC { get; set; }

Declaration

public static ParsingConfig DefaultCosmosDb { get; }

Property Value

Type	Description
ParsingConfig

DefaultEFCore21

Default ParsingConfig for EntityFramework Core 2.1 and higher

Declaration

public static ParsingConfig DefaultEFCore21 { get; }

Property Value

Type	Description
ParsingConfig

DisableMemberAccessToIndexAccessorFallback

By default when a member is not found in a type and the type has a string based index accessor it will be parsed as an index accessor. Use this flag to disable this behaviour and have parsing fail when parsing an expression where a member access on a non existing member happens.

Default value is false.

Declaration

public bool DisableMemberAccessToIndexAccessorFallback { get; set; }

Property Value

Type	Description
Boolean

EvaluateGroupByAtDatabase

Gets or sets a value indicating whether the EntityFramework version supports evaluating GroupBy at database level. See https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-2.1#linq-groupby-translation

Remark: when this setting is set to 'true', make sure to supply this ParsingConfig as first parameter on the extension methods.

Default value is false.

Declaration

public bool EvaluateGroupByAtDatabase { get; set; }

Property Value

Type	Description
Boolean

ExpressionPromoter

Gets or sets the IExpressionPromoter.

Declaration

public IExpressionPromoter ExpressionPromoter { get; set; }

Property Value

Type	Description
IExpressionPromoter

IsCaseSensitive

Gets or sets if parameter, method, and properties resolution should be case sensitive or not (false by default).

Declaration

public bool IsCaseSensitive { get; set; }

Property Value

Type	Description
Boolean

NullPropagatingUseDefaultValueForNonNullableValueTypes

When using the NullPropagating function np(...), use a "default value" for non-nullable value types instead of "null value".

Default value is false.

Declaration

public bool NullPropagatingUseDefaultValueForNonNullableValueTypes { get; set; }

Property Value

Type	Description
Boolean

NumberParseCulture

The number parsing culture.

Default value is CultureInfo.InvariantCulture

Declaration

public CultureInfo NumberParseCulture { get; set; }

Property Value

Type	Description
CultureInfo

PrioritizePropertyOrFieldOverTheType

When the type and property have the same name the parser takes the property instead of type when this setting is set to true.

This setting is also used for calling ExtensionMethods.

Default value is true.

Declaration

public bool PrioritizePropertyOrFieldOverTheType { get; set; }

Property Value

Type	Description
Boolean

QueryableAnalyzer

Gets or sets the IQueryableAnalyzer.

Declaration

public IQueryableAnalyzer QueryableAnalyzer { get; set; }

Property Value

RenameEmptyParameterExpressionNames

Prevents any System.Linq.Expressions.ParameterExpression.Name value from being empty by substituting a random 16 character word.

Default value is false.

Declaration

public bool RenameEmptyParameterExpressionNames { get; set; }

Property Value

Type	Description

RenameParameterExpression

Renames the (Typed)ParameterExpression empty Name to a the correct supplied name from it.

Default value is false.

Declaration

public bool RenameParameterExpression { get; set; }

ResolveTypesBySimpleName

By default finding types by a simple name is not supported. Use this flag to use the CustomTypeProvider to resolve types by a simple name like "Employee" instead of "MyDatabase.Entities.Employee".

Default value is false.

Declaration

public bool ResolveTypesBySimpleName { get; set; }

Property Value

Type	Description
Boolean

SupportCastingToFullyQualifiedTypeAsString
