SelectExpression.GenerateWeakEntityProjectionExpression 方法

定義

這是支援 Entity Framework Core 基礎結構的內部 API,不受與公用 API 相同的相容性標準。 它可能會在任何版本中變更或移除,而不會有任何通知。 您應該只在程式碼中直接使用它,並知道這麼做可能會導致應用程式在更新至新的 Entity Framework Core 版本時失敗。

[Microsoft.EntityFrameworkCore.Infrastructure.EntityFrameworkInternal]
public Microsoft.EntityFrameworkCore.Query.EntityProjectionExpression? GenerateWeakEntityProjectionExpression (Microsoft.EntityFrameworkCore.Metadata.IEntityType entityType, Microsoft.EntityFrameworkCore.Metadata.ITableBase table, string? columnName, Microsoft.EntityFrameworkCore.Query.SqlExpressions.TableExpressionBase tableExpressionBase, bool nullable = true);
[<Microsoft.EntityFrameworkCore.Infrastructure.EntityFrameworkInternal>]
member this.GenerateWeakEntityProjectionExpression : Microsoft.EntityFrameworkCore.Metadata.IEntityType * Microsoft.EntityFrameworkCore.Metadata.ITableBase * string * Microsoft.EntityFrameworkCore.Query.SqlExpressions.TableExpressionBase * bool -> Microsoft.EntityFrameworkCore.Query.EntityProjectionExpression
Public Function GenerateWeakEntityProjectionExpression (entityType As IEntityType, table As ITableBase, columnName As String, tableExpressionBase As TableExpressionBase, Optional nullable As Boolean = true) As EntityProjectionExpression
