c# - 使用自己的属性扩展 .NET MembershipUser

Question

我编写了一个自定义的 MembershipProvider，除了一件小事，它工作得非常好，我想稍微扩展一下 MembershipUser 类。

默认是这样的:

MembershipUser member = new MembershipUser(
    providerName: Membership.Provider.Name,
    name: db.userName,
    providerUserKey: null,
    email: db.userEmail,
    passwordQuestion: "",
    comment: "",
    isApproved: true,
    isLockedOut: false,
    creationDate: db.creationDate,
    lastLoginDate: db.lastLoginDate,
    lastActivityDate: db.lastActivityDate,
    lastPasswordChangedDate: DateTime.Now,
    lastLockoutDate: DateTime.Now
    );

但我想扩展一下，像这样:

MembershipUser member = new MembershipUser(
    providerName: Membership.Provider.Name,
    name: db.userName,
    guid: db.userGuid,
    company: db.companyName,
    companyGuid: db.companyGuid,
    whatever: db.whatever,
    providerUserKey: null,
    email: db.userEmail,
    passwordQuestion: "",
    comment: "",
    isApproved: true,
    isLockedOut: false,
    creationDate: db.creationDate,
    lastLoginDate: db.lastLoginDate,
    lastActivityDate: db.lastActivityDate,
    lastPasswordChangedDate: DateTime.Now,
    lastLockoutDate: DateTime.Now
    );

有没有办法扩展默认类？

Answer 1

当然可以!

只需创建一个扩展 MembershipUser 的类:

public class CustomUser : MembershipUser
{
    // your custom properties/methods go here
}

在您的 CustomMembershipProvider 中，您可以返回您的 CustomUser 对象。您只需在客户端应用程序中强制转换为 CustomUser。像这样:

var myUserObject = Membership.GetUser() as CustomUser;
