Question

我在github找到了解决我问题的方法 https://github.com/brandon-barker/PushBots.NET
但是在C＃中，我试图在很多站点中转换它，但它们都会抛出错误这里是原始的C＃代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using PushBots.NET;
using PushBots.NET.Models;
using PushBots.NET.Enums;
using System.Threading.Tasks;

public partial class Default3 : System.Web.UI.Page
{
        protected void Button1_Click(object sender, EventArgs e)
        {
            Run().Wait();
        }
        static async Task Run()
        {
            var client = new PushBotsClient("55165801f85f8b457d", "b03052506824b4f3165ecc0");
            var pushMessage = new BatchPush()
            {
                Message = "new Test from API",
                Badge = "+1",
                Platforms = new[] { Platform.Android, Platform.iOS }
            };
            var result = await client.Push(pushMessage);
        }
}

它工作正常但是当我将静态异步任务Run（）转换为VB时，我在VB中得到了很多错误

Private Shared Function Run() As Task
    Dim client = New PushBotsClient("55165801f85f8b457d", "b03052506824b4f3165ecc0")
Dim pushMessage = New BatchPush() With { _
    Key .Message = "new Test from API", _
    Key .Badge = "+1", _
    Key .Platforms = New () {Platform.Android, Platform.iOS} _
}
    Dim result = Await client.Push(pushMessage)
End Function

我得到的错误是Key （在对象初始值设定项中初始化的字段或属性的名称必须以＆＃39;开头。＆＃39;。）

第二个错误是Await （Await只能在Async方法中使用）

Answer 1

有几件事需要解决：

在方法声明中添加Async：

Private Shared Async Function Run() As Task

从Key块中删除With。在C＃ - ＆gt; VB转换期间添加Key为correct for anonymous classes，但对于非匿名类属性初始化则不行。

换句话说，
C＃new { ID = 3 }对应于VB New With { Key .ID = 3 }，但是 C＃new MyClass { ID = 3 }应该成为New MyClass With { .ID = 3 }。
New()，即.Platforms = {Platform.Android, Platform.iOS}就足够了。

Answer 2

您需要在功能签名中添加Async。

Private Shared Async Function Run() As Task

将C＃转换为VB.NET：在对象初始值设定项中初始化的字段或属性的名称必须以＆＃39;开头。＆＃39;
