命名空间:

Microsoft.EntityFrameworkCore.Query

程序集:

Microsoft.EntityFrameworkCore.Relational.dll

包:

Microsoft.EntityFrameworkCore.Relational v8.0.0

Join<TOuter,TInner,TKey,TResult>(IQueryable<TOuter>, IEnumerable<TInner>, Expression<Func<TOuter,TKey>>, Expression<Func<TInner,TKey>>, Expression<Func<TOuter,TInner,TResult>>)转换给定源上的方法。

protected override Microsoft.EntityFrameworkCore.Query.ShapedQueryExpression? TranslateJoin (Microsoft.EntityFrameworkCore.Query.ShapedQueryExpression outer, Microsoft.EntityFrameworkCore.Query.ShapedQueryExpression inner, System.Linq.Expressions.LambdaExpression outerKeySelector, System.Linq.Expressions.LambdaExpression innerKeySelector, System.Linq.Expressions.LambdaExpression resultSelector);

override this.TranslateJoin : Microsoft.EntityFrameworkCore.Query.ShapedQueryExpression * Microsoft.EntityFrameworkCore.Query.ShapedQueryExpression * System.Linq.Expressions.LambdaExpression * System.Linq.Expressions.LambdaExpression * System.Linq.Expressions.LambdaExpression -> Microsoft.EntityFrameworkCore.Query.ShapedQueryExpression
