C# 重写GetRolesAsync

我想做的是

public override Task<IList<string>> GetRolesAsync(ApplicationUser user, CancellationToken cancellationToken = default)
{
    return Context.UserOrganisationRole
        .Where(z => z.UserId == user.Id)
        .GroupBy(z => new { z.RoleId, z.Role })
        .Select(z => z.Key.Role.Name + "-" + string.Join(",", z.OrderBy(z => z.OrganisationId).Select(z => z.OrganisationId)))
        .ToListAsync();
}

也就是说，给我写这个

public Task<IList<string>> ListToTaskIList (IList<string> list)
{

}

公共任务列表totaskilist（IList列表）
{
}

只需等待查询结果：

public async override Task<IList<string>> GetRolesAsync(ApplicationUser user, CancellationToken cancellationToken = default)
{
    return await Context.UserOrganisationRole
        .Where(z => z.UserId == user.Id)
        .GroupBy(z => new { z.RoleId, z.Role })
        .Select(z => z.Key.Role.Name + "-" + string.Join(",", z.OrderBy(z => z.OrganisationId).Select(z => z.OrganisationId)))
        .ToListAsync();
}

公共异步覆盖任务GetRolesAsync（ApplicationUser用户，CancellationToken CancellationToken=default）
{
return wait Context.userOrganizationRole
.Where（z=>z.UserId==user.Id）
.GroupBy（z=>new{z.RoleId，z.Role}）
.Select（z=>z.Key.Role.Name+“-”+string.Join（“，”，z.OrderBy（z=>z.organizationId）。Select（z=>z.organizationId）））
.ToListAsync（）；
}

public Task<IList<string>> ListToTaskIList (IList<string> list)
{

}

public async override Task<IList<string>> GetRolesAsync(ApplicationUser user, CancellationToken cancellationToken = default)
{
    return await Context.UserOrganisationRole
        .Where(z => z.UserId == user.Id)
        .GroupBy(z => new { z.RoleId, z.Role })
        .Select(z => z.Key.Role.Name + "-" + string.Join(",", z.OrderBy(z => z.OrganisationId).Select(z => z.OrganisationId)))
        .ToListAsync();
}
