    IEnumerable<SelectedItem>? items = null;
    if (key == "Foo.Complete")
    {
        var users = SysUserService.GetAllUsersAsync().Result;
        //var localizer = Provider.GetRequiredService<IStringLocalizer<Foo>>();//多语言支持
        items = users.Select(user => new SelectedItem
        { Value = user.Id.ToString(), Text = user.Name }).ToList();

    }
    return items;

.Result是同步方法啊，阻塞不是正常现象吗

@SmartCode-X @BrandonStudio Blazor 的世界里可以说有两条定理

async void

.Result

大概率都会遇到问题。各种各样的问题。
