C# 无法将参数值从HashSet`1转换为IEnumerable`1

我在存储过程中有一个用户定义的值类型参数，我可以成功运行存储过程，但在从代码调用它时，我收到了这个错误

无法将参数值从HashSet1转换为IEnumerable1

我尝试过另一个类似的问题，但没有找到任何解决方案。请帮我解决这个问题

执行下面的方法后，我得到

无法将参数值从HashSet1转换为IEnumerable1

此错误

并且该错误实际上表示HashSet`1而不是特定类型？是的，它表示无法将参数值从HashSet1转换为IEnumerable1。问题可能出在GetBusinessesQueries.FromSqlRaw中，此处未提供此问题。还请提供完整的堆栈跟踪以及异常消息。它只是一个虚拟数据库集公共虚拟数据库集GetBusinessQueries{get；set；}您是否尝试将updateRole.RoleFeatures转换为数据表？

public async Task UpdateRole(Role updateRole)
    {
        var parameters = new List<SqlParameter>
        {
            new SqlParameter("@BusinessId", updateRole.BusinessId),
            new SqlParameter("@Id", updateRole.Id),
            new SqlParameter("@Name", updateRole.Name),
            new SqlParameter("@Description", updateRole.Description ?? (object)DBNull.Value),
            new SqlParameter("@IsActive", updateRole.IsActive ?? (object)DBNull.Value),
            new SqlParameter
            {
                SqlDbType=SqlDbType.Structured,
                Direction=ParameterDirection.Input,
                ParameterName="@FeatureIds",
                TypeName="[dbo].[ParameterList]",
                Value=updateRole.RoleFeatures
            },
        };

        await GetBusinessesQueries.FromSqlRaw("EXEC UpdateRole @BusinessId, @Id, @Name, @Description, @IsActive, @FeatureIds",
            parameters.ToArray()).ToListAsync();
    }
