Overloads

ValueConverter(LambdaExpression, LambdaExpression, ConverterMappingHints)

Initializes a new instance of the ValueConverter class.
ValueConverter(LambdaExpression, LambdaExpression, Boolean, ConverterMappingHints)

Initializes a new instance of the ValueConverter class, allowing conversion of nulls.

Warning: this is currently an internal API since converting nulls to and from the database can lead to broken queries and other issues. See GitHub issue #26230 for more information and examples.

ValueConverter(LambdaExpression, LambdaExpression, ConverterMappingHints)

Initializes a new instance of the ValueConverter class.

protected ValueConverter (System.Linq.Expressions.LambdaExpression convertToProviderExpression, System.Linq.Expressions.LambdaExpression convertFromProviderExpression, Microsoft.EntityFrameworkCore.Storage.ValueConversion.ConverterMappingHints mappingHints = default);
protected ValueConverter (System.Linq.Expressions.LambdaExpression convertToProviderExpression, System.Linq.Expressions.LambdaExpression convertFromProviderExpression, Microsoft.EntityFrameworkCore.Storage.ValueConversion.ConverterMappingHints? mappingHints = default);
new Microsoft.EntityFrameworkCore.Storage.ValueConversion.ValueConverter : System.Linq.Expressions.LambdaExpression * System.Linq.Expressions.LambdaExpression * Microsoft.EntityFrameworkCore.Storage.ValueConversion.ConverterMappingHints -> Microsoft.EntityFrameworkCore.Storage.ValueConversion.ValueConverter
Protected Sub New (convertToProviderExpression As LambdaExpression, convertFromProviderExpression As LambdaExpression, Optional mappingHints As ConverterMappingHints = Nothing)

Parameters

convertToProviderExpression
LambdaExpression

The expression to convert objects when writing data to the store, exactly as supplied and may not handle nulls, boxing, and non-exact matches of simple types.

convertFromProviderExpression
LambdaExpression

The expression to convert objects when reading data from the store, exactly as supplied and may not handle nulls, boxing, and non-exact matches of simple types.

mappingHints
ConverterMappingHints

Hints that can be used by the ITypeMappingSource to create data types with appropriate facets for the converted data.

Remarks

See EF Core value converters for more information and examples.

Protected Sub New (convertToProviderExpression As LambdaExpression, convertFromProviderExpression As LambdaExpression, convertsNulls As Boolean, Optional mappingHints As ConverterMappingHints = Nothing)

Parameters

convertToProviderExpression
LambdaExpression

The expression to convert objects when writing data to the store, exactly as supplied and may not handle nulls, boxing, and non-exact matches of simple types.

convertFromProviderExpression
LambdaExpression

The expression to convert objects when reading data from the store, exactly as supplied and may not handle nulls, boxing, and non-exact matches of simple types.

convertsNulls
Boolean

If true, then the nulls will be passed to the converter for conversion. Otherwise null values always remain null.

mappingHints
ConverterMappingHints

Hints that can be used by the ITypeMappingSource to create data types with appropriate facets for the converted data.
