如何在Razor Pages中实现两个具有独立BindProperties的表单？

@page
@model IndexModel

<form method="post" asp-page-handler="Form1">
    <input type="text" name="Field1" asp-for="Form1Data.Field1" />
    <input type="text" name="Field2" asp-for="Form1Data.Field2" />
    <button type="submit">Submit Form 1</button>
</form>

<form method="post" asp-page-handler="Form2">
    <input type="text" name="FieldA" asp-for="Form2Data.FieldA" />
    <input type="text" name="FieldB" asp-for="Form2Data.FieldB" />
    <button type="submit">Submit Form 2</button>
</form>

public class IndexModel : PageModel
{
    [BindProperty]
    public Form1Model Form1Data { get; set; }

    [BindProperty]
    public Form2Model Form2Data { get; set; }

    public void OnPostForm1()
    {
        // 处理表单1的数据
        if (ModelState.IsValid)
        {
            // 处理逻辑
        }
    }

    public void OnPostForm2()
    {
        // 处理表单2的数据
        if (ModelState.IsValid)
        {
            // 处理逻辑
        }
    }
}

public class Form1Model
{
    public string Field1 { get; set; }
    public string Field2 { get; set; }
}

public class Form2Model
{
    public string FieldA { get; set; }
    public string FieldB { get; set; }
}
