定义

命名空间:

Microsoft.EntityFrameworkCore.Storage

程序集:

Microsoft.EntityFrameworkCore.dll

包:

Microsoft.EntityFrameworkCore v8.0.0

重载

Clone(CoreTypeMapping+CoreTypeMappingParameters)	创建此映射的副本。
Clone(Nullable<TypeMappingInfo>, Type, ValueConverter, ValueComparer, ValueComparer, ValueComparer, CoreTypeMapping, JsonValueReaderWriter)	克隆类型映射以根据需要更新任何参数。

Clone(CoreTypeMapping+CoreTypeMappingParameters)

创建此映射的副本。

protected abstract Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping Clone (Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping.CoreTypeMappingParameters parameters);

abstract member Clone : Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping.CoreTypeMappingParameters -> Microsoft.EntityFrameworkCore.Storage.CoreTypeMapping

Protected MustOverride Function Clone (parameters As CoreTypeMapping.CoreTypeMappingParameters) As CoreTypeMapping

参数

parameters

CoreTypeMapping.CoreTypeMappingParameters

此映射的参数。

返回

CoreTypeMapping

新创建的映射。

Clone(Nullable<TypeMappingInfo>, Type, ValueConverter, ValueComparer, ValueComparer, ValueComparer, CoreTypeMapping, JsonValueReaderWriter)

克隆类型映射以根据需要更新任何参数。

参数

mappingInfo

Nullable<TypeMappingInfo>

包含要使用的 Facet 的映射信息。

clrType

Type

EF 模型中使用的 .NET 类型，或者 null 保持不变。

converter

ValueConverter

值转换器，或 null 保留不变。

comparer

ValueComparer

值比较器，或 null 保留不变。

keyComparer

ValueComparer

键值比较器，或 null 保留不变。

providerValueComparer

ValueComparer

提供程序值比较器，或 null 保留不变。

elementMapping

CoreTypeMapping

元素映射，或 null 保留不变。

jsonValueReaderWriter

JsonValueReaderWriter

JSON 读取器/编写器，或 null ，以保持不变。

返回

CoreTypeMapping

克隆的映射，或者原始映射（如果不需要克隆）。
