注意

Use SetValueComparer. Only a single value comparer is allowed for a given property.

在执行键比较时，为此属性设置自定义 ValueComparer 。

public static void SetKeyValueComparer (this Microsoft.EntityFrameworkCore.Metadata.IMutableProperty property, Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer comparer);

[System.Obsolete("Use SetValueComparer. Only a single value comparer is allowed for a given property.")]
public static void SetKeyValueComparer (this Microsoft.EntityFrameworkCore.Metadata.IMutableProperty property, Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer comparer);

[System.Obsolete("Use SetValueComparer. Only a single value comparer is allowed for a given property.")]
public static void SetKeyValueComparer (this Microsoft.EntityFrameworkCore.Metadata.IMutableProperty property, Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer? comparer);

static member SetKeyValueComparer : Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer -> unit

[<System.Obsolete("Use SetValueComparer. Only a single value comparer is allowed for a given property.")>]
static member SetKeyValueComparer : Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.ChangeTracking.ValueComparer -> unit
