Csharp 为什么我的表单在绑定到对象时提交空值

我使用的是.NET 8.0

当我提交表单并将结果打印到控制台时，它会给出表单的默认值.在本例中，它们中的每一个都为空.

以下是Form和Blazor代码块的代码.

根据我所看到的，我正在创建类的一个新实例，将每个属性绑定到表单中的类，然后转换为JSON并打印.我遗漏了什么？

<EditForm Model="@addressToBeCorrected" FormName="addressForm" OnValidSubmit="HandleValidSubmit">
    <DataAnnotationsValidator />

    <div class="form-group col-md-4">
        <label for="Number">Number</label>
        <InputText id="Number" class="form-control" @bind-Value="@addressToBeCorrected.Number" />
    </div>

    <div class="form-group col-md-4">
        <label for="Street">Street</label>
        <InputText id="Street" class="form-control" @bind-Value="@addressToBeCorrected.Street" />
    </div>

    <div class="form-group col-md-4">
        <label for="Unit">Unit</label>
        <InputText id="Unit" class="form-control" @bind-Value="@addressToBeCorrected.Unit" />
    </div>

    <div class="form-group col-md-4">
        <label for="City">City</label>
        <InputText id="City" class="form-control" @bind-Value="@addressToBeCorrected.City" />
    </div>

    <div class="form-group col-md-4">
        <label for="Postcode">Postcode</label>
        <InputText id="Postcode" class="form-control" @bind-Value="@addressToBeCorrected.Postcode" />
    </div>

    <div class="form-group col-md-4">
        <label for="Region">Region</label>
        <InputText id="Region" class="form-control" @bind-Value="@addressToBeCorrected.Region" />
    </div>

    <button type="submit" class="btn btn-primary">Submit</button>
</EditForm>

@code {
    private Models.InputAddress addressToBeCorrected = new Models.InputAddress();

    private async Task HandleValidSubmit()
    {
        Console.WriteLine(addressToBeCorrected.Number);

        // convert the InputAddress object to a JSON string
        string json = JsonSerializer.Serialize(addressToBeCorrected);

        Console.WriteLine(json);
        // send the JSON string to the server
    }
}

以下是InputAddress类的代码:

public class InputAddress

{
    public string? Number { get; set; }
    public string? Street { get; set; }
    public string? Unit { get; set; }
    public string? City { get; set; }
    public string? Postcode { get; set; }
    public string? Region { get; set; }
}

感谢下面的 comments 者，我遇到的问题是因为我没有使用@rendermode设置页面的互动性.这件事就这样解决了.
