我需要将我的登录设置为使用用户名而不是电子邮件地址，我该如何更改?我到处看，但他们是MVC代码不是web表单。

我很感激你为解决我的问题所做的努力。

如何使用“用户名”登录而不是“电子邮件地址”;在ASP.Net Web表单身份

您可以简单地通过用户名或您想要的任何内容找到用户，然后直接使用SignIn方法登录用户:

protected void LogIn(object sender, EventArgs e)
{
    if (IsValid)
    {
        // Validate the user password
        var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
        var signinManager = Context.GetOwinContext().GetUserManager<ApplicationSignInManager>();
        // assuming you have a text box named UserName
        var user=manager.FindByName(UserName.Text);
        // or for advanced scenarios you can write:
        // var user = manager.Users.FirstOrDefault(u => u.UserName == UserName.Text);
        if(user !=null)
        {
            if(manager.CheckPassword(user, Password.Text))
            {
                signinManager.SignIn(user, false, RememberMe.Checked);
                IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response);
            }
        }
    }
    FailureText.Text = "Invalid login attempt";
    ErrorMessage.Visible = true;
}

如果你看一下SignInManagerExtensions。在MSDN中，这将告诉您PasswordSignIn方法中的第一个参数是userName。

MVC,WebForms在注册电子邮件地址时默认设置为Email。您也可以更改注册操作，以允许注册用户名，这在默认情况下将电子邮件添加为用户名和电子邮件在数据库中。

protected void CreateUser_Click(object sender, EventArgs e)
{
    // ...
    // UserName and Email are both set to Email.text
    // Add a UserName TextBox and Replace UserName = Email.Text with UserName = UserName.Text
    var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text };
    // ...
}

protected void LogIn(object sender, EventArgs e)
{
    if (IsValid)
    {
        // ...
        // The first argument is userName
        // Replace mail.Text with UserName.Text
        var result = signinManager.PasswordSignIn(mail.Text, Password.Text, RememberMe.Checked, shouldLockout: false);
        // ..
    }
}

替换:

<div class="form-group">
    <asp:Label runat="server" AssociatedControlID="Email" CssClass="col-md-2 control-label">Email</asp:Label>
    <div class="col-md-10">
        <asp:TextBox runat="server" ID="Email" CssClass="form-control" TextMode="Email" />
        <asp:RequiredFieldValidator runat="server" ControlToValidate="Email"
            CssClass="text-danger" ErrorMessage="The email field is required." />
    </div>
</div>

: 

<div class="form-group">
    <asp:Label runat="server" AssociatedControlID="UserName" CssClass="col-md-2 control-label">UserName</asp:Label>
    <div class="col-md-10">
        <asp:TextBox runat="server" ID="UserName" CssClass="form-control" />
        <asp:RequiredFieldValidator runat="server" ControlToValidate="UserName"
            CssClass="text-danger" ErrorMessage="The username field is required." />
    </div>
</div>
