根据Blazor中的键从集合中移除子组件的Renderfragment

Question

我将子组件存储在字典中，并尝试从集合中删除键= 1，但最后一行将被删除并且键被操纵。

Initially added child components to parent
After trying to remove the key 1 from the collection

请在下面找到我尝试使用blazor webassembly的描述：

当用户告诉Addme时，我正在将子组件作为renderfragments添加到主组件中的字典中。 同样，当用户提供行号并单击Deleteme时，我正在尝试根据字典键删除renderfragment。 我正在循环字典并显示所有子组件。但是我观察到总是删除字典中的最后一个元素，并且删除后按键错误地指向了Renderfragment。 请帮助我。

Please find the parent component code below:

@page "/counter"
    
    <h1>Counter</h1>
    
    <button class="btn btn-primary" @onclick="IncrementCount">Add me</button>
    <br />
    
    <button class="btn btn-primary" @onclick="Remove">Delete me</button>
    <label>Enter row number to delete:</label>
    <input type="text" @bind-value="@getKey">
    <br />
    
    <label>CollectionCount: @dicCount</label>
    <label>Counter count: @currentCount</label>
    
    @{
        var dic = MyDic.OrderBy(x => x.Key).ToList();
    }
    @foreach (var item in dic)
    {
        <br />
        <label>Row Number:</label>
        <label>@item.Key</label>
        @item.Value;
    
    }
    
    @code {
        private Dictionary<int, RenderFragment> MyDic { get; set; } = new Dictionary<int, RenderFragment>();
    
        public int getKey { get; set; }
    
        private int currentCount = 0;
    
        private int dicCount = 0;
    
        public RenderFragment ChildRef { get; set; }
    
        private void IncrementCount()
        {
            ChildRef = builder =>
            {
                builder.OpenComponent<Child>(1);
                builder.CloseComponent();
            };
            MyDic.Add(currentCount, ChildRef);
            ChildRef = null;
            dicCount = MyDic.Count;
            currentCount++;
        }
    
        private void Remove()
        {
            MyDic.Remove(getKey);
        }
    }
    
    Please find the child code below:
    
    <h3>Child</h3>
    
    <label>Renderfragment loaded</label>
    <label>@RandomNumber</label>
    
    @code {
    
        // Instantiate random number generator.
        private readonly Random _random = new Random();
    
        public string RandomNumber { get; set; }
    
        protected override async Task OnInitializedAsync()
        {`enter code here`
            RandomNumber = _random.Next().ToString();
        }
    }
