public static Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer CreateDefault(Type type, bool favorStructuralComparisons);
[System.Diagnostics.CodeAnalysis.RequiresDynamicCode("Creating a default value comparer for the given type requires calling MakeGenericMethod, which is not compatible with NativeAOT. Use the generic CreateDefault<T> overload instead.")]

static member CreateDefault : Type * bool -> Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer
[<System.Diagnostics.CodeAnalysis.RequiresDynamicCode("Creating a default value comparer for the given type requires calling MakeGenericMethod, which is not compatible with NativeAOT. Use the generic CreateDefault<T> overload instead.")>]
static member CreateDefault : Type * bool -> Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer
Public Shared Function CreateDefault (type As Type, favorStructuralComparisons As Boolean) As ValueComparer

参数

type
Type

类型。

favorStructuralComparisons
Boolean

如果 true，则 EF 将使用该 IStructuralEquatable 类型来实现它。 这通常在字节数组充当键时使用。

返回

ValueComparer

ValueComparer<T>。

特性
RequiresDynamicCodeAttribute
