RuntimeDbFunction 建構函式

定義

命名空間:

Microsoft.EntityFrameworkCore.Metadata

組件:

Microsoft.EntityFrameworkCore.Relational.dll

套件:

Microsoft.EntityFrameworkCore.Relational v8.0.0

初始化 RuntimeDbFunction 類別的新執行個體。

public RuntimeDbFunction (string modelName, Microsoft.EntityFrameworkCore.Metadata.RuntimeModel model, Type returnType, string storeName, string? schema = default, string? storeType = default, System.Reflection.MethodInfo? methodInfo = default, bool scalar = false, bool aggregate = false, bool nullable = false, bool builtIn = false, Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping? typeMapping = default, Func<System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression>,Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression>? translation = default);

new Microsoft.EntityFrameworkCore.Metadata.RuntimeDbFunction : string * Microsoft.EntityFrameworkCore.Metadata.RuntimeModel * Type * string * string * string * System.Reflection.MethodInfo * bool * bool * bool * bool * Microsoft.EntityFrameworkCore.Storage.RelationalTypeMapping * Func<System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression>, Microsoft.EntityFrameworkCore.Query.SqlExpressions.SqlExpression> -> Microsoft.EntityFrameworkCore.Metadata.RuntimeDbFunction

Public Sub New (modelName As String, model As RuntimeModel, returnType As Type, storeName As String, Optional schema As String = Nothing, Optional storeType As String = Nothing, Optional methodInfo As MethodInfo = Nothing, Optional scalar As Boolean = false, Optional aggregate As Boolean = false, Optional nullable As Boolean = false, Optional builtIn As Boolean = false, Optional typeMapping As RelationalTypeMapping = Nothing, Optional translation As Func(Of IReadOnlyList(Of SqlExpression), SqlExpression) = Nothing)
