如何在Blazor中绑定单选按钮？

public bool IsSelected { get; set; }

<input type="radio" @bind="@IsSelected" />

<input type="radio" name="myRadioGroup" @bind="@IsSelected" value="option1" />
<input type="radio" name="myRadioGroup" @bind="@IsSelected" value="option2" />
<input type="radio" name="myRadioGroup" @bind="@IsSelected" value="option3" />

@implements IInputFile

<input type="radio" name="myRadioGroup" @bind="@IsSelected" value="option1" />

@code {
    public bool IsSelected { get; set; }

    void IInputFile.OpenFile() { }
    Task IInputFile.RaiseInputFileChangedAsync() => Task.CompletedTask;
}
