從 azure 檢索數據時，列表視圖未顯示我的結果

Question

這是我的代碼

  public  List<string> Mycollection { get; set; } = new List<string>();
    public async void Button_Clicked(object sender, EventArgs e)
    {            
        string storageConnectionString = "mystring";           
        CloudStorageAccount storageAccount = DOTFORMS3.Common.CreateStorageAccountFromConnectionString(storageConnectionString);
        CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
        CloudTable table = tableClient.GetTableReference("tablename");
        TableQuery<CustomerEntity> tableQuery = new TableQuery<CustomerEntity>();
        foreach (CustomerEntity CustomerEntity in table.ExecuteQuery(tableQuery))
        {
            Mycollection.Add(CustomerEntity.NAME);
        }
        await Navigation.PushModalAsync(new Mynewpage());
    }

這是我的 Mynewpage Xaml 代碼

 <ContentPage.BindingContext>
    <vm:Page1/>
</ContentPage.BindingContext>  
        <StackLayout> 
          <Label Text="koool"></Label>
        <ListView ItemsSource="{Binding Mycollection }">                
        </ListView>
    <Label Text="koool"></Label>
</StackLayout>

這是 output 的圖像 在此處輸入圖像描述一切似乎都很好，但我想問題出在我使用綁定的方式上

您需要將數據傳遞到您的頁面。 這不會自動發生

await Navigation.PushModalAsync(new Mynewpage(Mycollection));

然后在Mynewpage

public List<string> Mycollection { get; set; }

public Mynewpage(List<string> data)
{
  ...

  Mycollection = data;

  this.BindingContext = this;
  ...
}

擺脫這個

<ContentPage.BindingContext>
    <vm:Page1/>
</ContentPage.BindingContext>
