.NET核心MVC中文件输入的远程验证

public class MyModel
{
    [Required]
    [Remote(action: "ValidateFile", controller: "Home")]
    public IFormFile MyFile { get; set; }
}

public class HomeController : Controller
{
    [HttpPost]
    public IActionResult ValidateFile(IFormFile myFile)
    {
        // 进行文件验证的逻辑处理
        if (myFile == null || myFile.Length == 0)
        {
            return Json("请选择一个文件。");
        }

        // 其他验证逻辑...

        return Json(true);
    }
}

<form asp-action="Upload" enctype="multipart/form-data">
    <div class="form-group">
        <label asp-for="MyFile"></label>
        <input asp-for="MyFile" type="file" class="form-control" />
        <span asp-validation-for="MyFile" class="text-danger"></span>
