这是Entity Framework Core功能使用的实验性 API，它不受与公共 API 相同的兼容性标准的约束。 可以在任何版本中更改或删除它，而不通知。 只需在代码中直接使用它，并非常谨慎地知道这样做可能会导致应用程序在更新到新的Entity Framework Core版本时失败。

public virtual Microsoft.EntityFrameworkCore.Query.LiftableConstantExpression CreateLiftableConstant(object? originalValue, System.Linq.Expressions.Expression<Func<Microsoft.EntityFrameworkCore.Query.RelationalMaterializerLiftableConstantContext,object>> resolverExpression, string variableName, Type type);

override this.CreateLiftableConstant : obj * System.Linq.Expressions.Expression<Func<Microsoft.EntityFrameworkCore.Query.RelationalMaterializerLiftableConstantContext, obj>> * string * Type -> Microsoft.EntityFrameworkCore.Query.LiftableConstantExpression
