HasFilter(IConventionIndexBuilder, String, Boolean)

設定索引的篩選運算式。

public static Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionIndexBuilder? HasFilter (this Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionIndexBuilder indexBuilder, string? sql, bool fromDataAnnotation = false);

static member HasFilter : Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionIndexBuilder * string * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionIndexBuilder

<Extension()>
Public Function HasFilter (indexBuilder As IConventionIndexBuilder, sql As String, Optional fromDataAnnotation As Boolean = false) As IConventionIndexBuilder

參數

indexBuilder

IConventionIndexBuilder
