Sas Gabriel's questions

我刚刚创建了一个新的 .net blazor web 应用项目并添加了此代码

@page "/weather"

@attribute [StreamRendering] @rendermode InteractiveServer <PageTitle>Weather</PageTitle>

<h1>Weather</h1>

@using System.Diagnostics

<h3>Dropdown Example</h3>

<select @bind="SelectedSet" class="form-select">
    <option disabled selected value="">-- Select a Set --</option>
    @foreach (var set in Sets)
    {
        <option value="@set">@set</option>
    } </select> <p>You selected: @SelectedSet</p>

<div class="mb-3">
    <label for="SetType" class="form-label">Set Type</label>
    <InputSelect id="SetType" @bind-Value="CollectionSet" class="form-select">
        @foreach (var set in Sets)
        {
            <option value="@set">@set</option>
        }
    </InputSelect> </div> <p>You selected: @CollectionSet</p>

@code {
    private List<string> Sets = new List<string> { "Pad", "Leather", "Bronze" };
    private string SelectedSet { get; set; }
    private string CollectionSet { get; set; }

    private void OnSetChanged(ChangeEventArgs e)
    {
        Debug.WriteLine($"Selected value changed to: {SelectedSet}");
        // Additional logic can be added here
    } }

但是当我在方法上设置断点时，它就是不起作用。我不明白为什么事件没有触发。起初我使用枚举，我以为是因为这个原因，但对于一个简单的字符串，它仍然不起作用
