第三步：在方法Process上选择添加视图，如下图选择：
如此共生成五个view页面：step1.step2，step3，step4，step5，Final。
第四步：设计状态机工作流。这里只演示step1的设置，如下图：
将一个用户的注册分成了四步，而这四个步骤都是在完善一个Model的信息，但是又分页面填写信息的，当时我加上ModelState.IsValid这句验证代码的时候，根本没法通过验证，因为在注册的前面三步，注册用户的Model信息都没填写完整，而ModelState.IsValid是对一个实体的所有属性进行判断验证的。当时很纠结，因为刚接触Asp.net MVC，故没有找到解决方案。这篇文章将给出解决的办法。看下面需要验证的Model的代码如下：
public class UserViewModel
{
[DisplayName("step")]
[Required(ErrorMessage = "You must select a step .")]
public int Step { get; set; }
//个人信息
[Required(ErrorMessage = "姓名不能为空")]
[StringLength(20, ErrorMessage = "姓名长度不能超过20个字符")]
public string Name { get; set; }
[RegularExpression(@"120|((1[0-1]|\d)?\d)", ErrorMessage = "年龄格式不对")]
public int? Age { get; set; }
//职位信息
[Required(ErrorMessage = "职位不能为空")]
public string Post { get; set; }
public int? Salary { get; set; }
//学历信息
[Required(ErrorMessage = "毕业院校不能为空")]
public string University { get; set; } public int? GraduationYear { get; set; }
//联系信息
[Required(ErrorMessage = "邮件不能为空")]
[RegularExpression(@"^[a-z][a-z|0-9|]*([_][a-z|0-9]+)*([.][a-z|" + @"0-9]+([_][a-z|0-9]+)*)?@[a-z][a-z|0-9|]*\.([a-z]" + @"[a-z|0-9]*(\.[a-z][a-z|0-9]*)?)$", ErrorMessage= "邮件格式不正确")]
public string Email { get; set; }
public int? Mobile { get; set; }
public IEnumerable<SelectListItem> StepList { get; set; }
public UserViewModel()
{
var list = new List<SelectListItem>() {
new SelectListItem { Text = "(Select)" },
new SelectListItem { Value = "1", Text = "Step1" },
new SelectListItem { Value = "2", Text = "Step2" },
new SelectListItem { Value = "3", Text = "Step3" },
new SelectListItem { Value = "4", Text = "Step4" } }; this.StepList = new SelectList(list, "Value", "Text");
}
}
{
[DisplayName("step")]
[Required(ErrorMessage = "You must select a step .")]
public int Step { get; set; }
//个人信息
[Required(ErrorMessage = "姓名不能为空")]
[StringLength(20, ErrorMessage = "姓名长度不能超过20个字符")]
public string Name { get; set; }
[RegularExpression(@"120|((1[0-1]|\d)?\d)", ErrorMessage = "年龄格式不对")]
public int? Age { get; set; }
//职位信息
[Required(ErrorMessage = "职位不能为空")]
public string Post { get; set; }
public int? Salary { get; set; }
//学历信息
[Required(ErrorMessage = "毕业院校不能为空")]
public string University { get; set; } public int? GraduationYear { get; set; }
//联系信息
[Required(ErrorMessage = "邮件不能为空")]
[RegularExpression(@"^[a-z][a-z|0-9|]*([_][a-z|0-9]+)*([.][a-z|" + @"0-9]+([_][a-z|0-9]+)*)?@[a-z][a-z|0-9|]*\.([a-z]" + @"[a-z|0-9]*(\.[a-z][a-z|0-9]*)?)$", ErrorMessage= "邮件格式不正确")]
public string Email { get; set; }
public int? Mobile { get; set; }
public IEnumerable<SelectListItem> StepList { get; set; }
public UserViewModel()
{
var list = new List<SelectListItem>() {
new SelectListItem { Text = "(Select)" },
new SelectListItem { Value = "1", Text = "Step1" },
new SelectListItem { Value = "2", Text = "Step2" },
new SelectListItem { Value = "3", Text = "Step3" },
new SelectListItem { Value = "4", Text = "Step4" } }; this.StepList = new SelectList(list, "Value", "Text");
}
}
