注意

现已弃用此 API。

创建一个新的 TypeMaterializationInfo 实例。

public TypeMaterializationInfo (Type modelClrType, Microsoft.EntityFrameworkCore.Metadata.IProperty property, Microsoft.EntityFrameworkCore.Storage.IRelationalTypeMappingSource typeMappingSource, int index = -1);

[System.Obsolete]
public TypeMaterializationInfo (Type modelClrType, Microsoft.EntityFrameworkCore.Metadata.IProperty property, Microsoft.EntityFrameworkCore.Storage.IRelationalTypeMappingSource typeMappingSource, int index = -1);

new Microsoft.EntityFrameworkCore.Storage.TypeMaterializationInfo : Type * Microsoft.EntityFrameworkCore.Metadata.IProperty * Microsoft.EntityFrameworkCore.Storage.IRelationalTypeMappingSource * int -> Microsoft.EntityFrameworkCore.Storage.TypeMaterializationInfo

[<System.Obsolete>]
new Microsoft.EntityFrameworkCore.Storage.TypeMaterializationInfo : Type * Microsoft.EntityFrameworkCore.Metadata.IProperty * Microsoft.EntityFrameworkCore.Storage.IRelationalTypeMappingSource * int -> Microsoft.EntityFrameworkCore.Storage.TypeMaterializationInfo

Public Sub New (modelClrType As Type, property As IProperty, typeMappingSource As IRelationalTypeMappingSource, Optional index As Integer = -1)

参数

modelClrType: Type

转换后模型中所需的类型。

property: IProperty

与类型关联的属性;如果没有， null 则为。

typeMappingSource: IRelationalTypeMappingSource

如果属性尚未绑定映射，则用于查找映射的类型映射源。

index: Int32

应用于此类型的基础结果集的索引;如果不需要索引映射，则为 -1。

属性: ObsoleteAttribute

适用于

TypeMaterializationInfo(Type, IProperty, RelationalTypeMapping, Nullable<Boolean>)

创建一个新的 TypeMaterializationInfo 实例。

public TypeMaterializationInfo (Type modelClrType, Microsoft.EntityFrameworkCore.Metadata.IProperty property, Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping mapping, bool? nullable = default);

public TypeMaterializationInfo (Type modelClrType, Microsoft.EntityFrameworkCore.Metadata.IProperty? property, Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping mapping, bool? nullable = default);

new Microsoft.EntityFrameworkCore.Storage.TypeMaterializationInfo : Type * Microsoft.EntityFrameworkCore.Metadata.IProperty * Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping * Nullable<bool> -> Microsoft.EntityFrameworkCore.Storage.TypeMaterializationInfo

Public Sub New (modelClrType As Type, property As IProperty, mapping As RelationalTypeMapping, Optional nullable As Nullable(Of Boolean) = Nothing)

参数

modelClrType: Type

转换后模型中所需的类型。

property: IProperty

与类型关联的属性;如果没有， null 则为。

mapping: RelationalTypeMapping

要使用或 null 推断的类型映射。

nullable: Nullable<Boolean>

一个值，该值指示该值是否可以为 null。
