ASP.NET Identity AllowOnlyAlphanumericUserNames

Question

有没有人可以帮助我如何在ASP中使用特殊字符?净身份?问题是我的用户不能用特殊字符注册:塞尔维亚，塞尔维亚，塞尔维亚，塞尔维亚，塞尔维亚。当你尝试在注册中输入这些字符时，我得到以下错误:用户名Krešo无效，只能包含字母或数字。

我可以在哪里以及如何改变这个。

代码如下:

using Microsoft.AspNet.Identity;
using Microsoft.Owin.Security;
using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Pages_Account_Register : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    protected void btnPrijava_Click(object sender, EventArgs e)
    {
        UserStore<IdentityUser> userStore = new UserStore<IdentityUser>();
        userStore.Context.Database.Connection.ConnectionString =
            System.Configuration.ConfigurationManager.ConnectionStrings["SeminariConnectionString3"].ConnectionString;
        UserManager<IdentityUser> manager = new UserManager<IdentityUser>(userStore);
        IdentityUser user = new IdentityUser();
        user.UserName = txtKorisnickoIme.Text;
        if(txtLozinka.Text == txtPotvrdaLozinke.Text)
        {
            try
            {
                IdentityResult result = manager.Create(user, txtLozinka.Text);
                if(result.Succeeded)
                {
                    var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
                    var userIdentity = manager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);
                    authenticationManager.SignIn(new AuthenticationProperties(), userIdentity);
                    Response.Redirect("Pocetna.aspx");
                }
                else
                {
                    litStatus.Text = result.Errors.FirstOrDefault();
                }
            }
            catch (Exception ex)
            {
                litStatus.Text = ex.ToString();
            }
        }
        else
        {
            litStatus.Text = "Lozinke moraju biti identične.";
        }

    }
}

您应该能够按照以下方式更改此行为:

var manager = new UserManager<IdentityUser>(userStore);  // existing code
var validator = manager.UserValidator as UserValidator<ApplicationUser>;
if (validator != null) validator.AllowOnlyAlphanumericUserNames = false;

如果validator结果为null，则稍微调试一下以找到运行时使用的实际类型
