如何在C＃中使用Dapper ORM从SQL数据库插入，更新，删除和查看学生资料数据

首先准备测试数据

创建数据表

CREATE TABLE [dbo].[UserInfo](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [FirstName] [nvarchar](50) NULL,
    [LastName] [nvarchar](50) NULL,
    [Email] [nvarchar](50) NULL,
    [Gender] [nvarchar](50) NULL,
    [IpAddress] [nvarchar](50) NULL,
 CONSTRAINT [PK_User] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

插入测试数据

insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Sigfrid', 'Mardee', 'smardee0@yellowpages.com', 'Male', '240.130.149.124');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Adair', 'McCulley', 'amcculley1@wunderground.com', 'Male', '117.91.155.101');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Archibald', 'Le Port', 'aleport2@goo.gl', 'Male', '71.216.30.7');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Antonin', 'Burling', 'aburling3@imgur.com', 'Male', '40.52.235.204');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Lyndsay', 'Lillie', 'llillie4@nytimes.com', 'Female', '226.133.26.233');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Dorice', 'Nijssen', 'dnijssen5@list-manage.com', 'Female', '17.234.233.192');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Fay', 'Card', 'fcard6@ycombinator.com', 'Female', '86.128.82.43');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Alicea', 'Bellhanger', 'abellhanger7@cbsnews.com', 'Female', '231.167.15.120');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Carine', 'Brisse', 'cbrisse8@europa.eu', 'Female', '18.31.36.220');
insert into UserInfo (FirstName, LastName, Email, Gender, IpAddress) values ('Amii', 'Sultan', 'asultan9@weather.com', 'Female', '64.193.222.168');
