命名空间:

Microsoft.EntityFrameworkCore.Storage

程序集:

Microsoft.EntityFrameworkCore.Relational.dll

包:

Microsoft.EntityFrameworkCore.Relational v8.0.0

返回此类型映射的新副本，并添加给定 ValueConverter 的 。

public override Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping WithComposedConverter (Microsoft.EntityFrameworkCore.Storage.ValueConversion.ValueConverter? converter, Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer? comparer = default, Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer? keyComparer = default, Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping? elementMapping = default, Microsoft.EntityFrameworkCore.Storage.Json.JsonValueReaderWriter? jsonValueReaderWriter = default);

override this.WithComposedConverter : Microsoft.EntityFrameworkCore.Storage.ValueConversion.ValueConverter * Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer * Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer * Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping * Microsoft.EntityFrameworkCore.Storage.Json.JsonValueReaderWriter -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Public Overrides Function WithComposedConverter (converter As ValueConverter, Optional comparer As ValueComparer = Nothing, Optional keyComparer As ValueComparer = Nothing, Optional elementMapping As CoreTypeMapping = Nothing, Optional jsonValueReaderWriter As JsonValueReaderWriter = Nothing) As CoreTypeMapping
