如何在 ASP.NET MVC 中验证文件类型

Question

在我的专业人员注册表中，我必须允许他们上传他们的简历，但我如何才能验证文件类型是否仅为 .docx 和 .pdf。另外，哪个最大重量为5mb？

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult RegistroProfesional(HttpPostedFileBase CV, TB_Profesionales p)
    {
        string n = Path.GetFileName(CV.FileName);
        string Folder = Path.Combine(Server.MapPath("~/ArchivosCV"), n);
        CV.SaveAs(Folder);
        int cant = db.SP_REGISTRAR_PROFESIONAL(p.TIPO, p.NOMBRE, p.APELLIDO, p.DNI,p.EMAIL, p.USUARIO, p.CLAVE, p.SEXO, p.FECHANAC, p.DISTRITO, p.IDSERVICIO, p.DESCRIPCIÓN, p.CV = n, p.PROMEDIOCAL);
        if (cant > 0)
        {
            return RedirectToAction("Login", "Login");
        }
        else
        {
            return RedirectToAction("ListadoProfesional");
        }
    }

试试下面的代码

        try  
        {  
            var supportedTypes = new[] { "docx","pdf"};  
            var fileExt = System.IO.Path.GetExtension(CV.FileName).Substring(1);  
            if (!supportedTypes.Contains(fileExt))  
            {  
                ErrorMessage = "File Extension Is Invalid - Only Upload DOCX and PDF";  
                return ErrorMessage;  
            }  
            else if (CV.ContentLength > (filesize * 1024))  
            {  
                ErrorMessage = "File size Should Be UpTo " + filesize + "KB";  
                return ErrorMessage;  
            }  
            else  
            {  
                ErrorMessage = "File Is Successfully Uploaded";  
                return ErrorMessage;  
            }  
        }  
        catch (Exception ex)  
        {  
            ErrorMessage = "Invalid file";  
            return ErrorMessage;  
        }
