RelationalGroupByResultExpression 建構函式

定義

命名空間:

Microsoft.EntityFrameworkCore.Query

組件:

Microsoft.EntityFrameworkCore.Relational.dll

套件:

Microsoft.EntityFrameworkCore.Relational v8.0.0

建立 RelationalGroupByResultExpression 類別的新執行個體。

public RelationalGroupByResultExpression (System.Linq.Expressions.Expression keyIdentifier, System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer> keyIdentifierValueComparers, System.Linq.Expressions.Expression keyShaper, System.Linq.Expressions.Expression elementShaper);

new Microsoft.EntityFrameworkCore.Query.RelationalGroupByResultExpression : System.Linq.Expressions.Expression * System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer> * System.Linq.Expressions.Expression * System.Linq.Expressions.Expression -> Microsoft.EntityFrameworkCore.Query.RelationalGroupByResultExpression

Public Sub New (keyIdentifier As Expression, keyIdentifierValueComparers As IReadOnlyList(Of ValueComparer), keyShaper As Expression, elementShaper As Expression)

參數

keyIdentifier

Expression

父元素的識別碼。

keyIdentifierValueComparers

IReadOnlyList<ValueComparer>

要比較父識別碼的值比較子清單。

keyShaper

Expression

運算式，用來建立集合的個別專案。

elementShaper

Expression

運算式，用來建立集合的個別專案。
