创建类的新实例 JsonQueryExpression 。

public JsonQueryExpression(Microsoft.EntityFrameworkCore.Metadata.IEntityType entityType, Microsoft.EntityFrameworkCore.Query.SqlExpressions.ColumnExpression jsonColumn, System.Collections.Generic.IReadOnlyDictionary<Microsoft.EntityFrameworkCore.Metadata.IProperty,Microsoft.EntityFrameworkCore.Query.SqlExpressions.ColumnExpression> keyPropertyMap, Type type, bool collection);

new Microsoft.EntityFrameworkCore.Query.JsonQueryExpression : Microsoft.EntityFrameworkCore.Metadata.IEntityType * Microsoft.EntityFrameworkCore.Query.SqlExpressions.ColumnExpression * System.Collections.Generic.IReadOnlyDictionary<Microsoft.EntityFrameworkCore.Metadata.IProperty, Microsoft.EntityFrameworkCore.Query.SqlExpressions.ColumnExpression> * Type * bool -> Microsoft.EntityFrameworkCore.Query.JsonQueryExpression

Public Sub New (entityType As IEntityType, jsonColumn As ColumnExpression, keyPropertyMap As IReadOnlyDictionary(Of IProperty, ColumnExpression), type As Type, collection As Boolean)

参数

entityType: IEntityType

此表达式所表示的实体类型。

jsonColumn: ColumnExpression

包含 JSON 值的列。

keyPropertyMap: IReadOnlyDictionary<IProperty,ColumnExpression>

它们映射到数据库中的键属性和列的映射。

type: Type

此表达式表示的元素的类型。

collection: Boolean

一个值，该值指示此表达式是否表示集合。
