正　文:

下面的代码实现向SQL Server数据库添加图片和文字的功能。

首先，在SQL查询分析器中执行下面的语句，以创建表和存储过程。

Drop Table Person

Go
Create Table Person
(
PersonID Int Identity,
PersonEmail Varchar(255),
PersonName Varchar(255),
PersonSex Char(1),
PersonDOB DateTime,
PersonImage Image,
PersonImageType Varchar(255)
)

Drop Proc sp_person_isp

Go
Create Proc sp_person_isp
@PersonEmail Varchar(255),
@PersonName Varchar(255),
@PersonSex Char(1),
@PersonDOB DateTime,
@PersonImage Image,
@PersonImageType Varchar(255)
As
Begin
Insert into Person
(PersonEmail, PersonName, PersonSex,
PersonDOB, PersonImage, PersonImageType)
Values
(@PersonEmail, @PersonName, @PersonSex,
@PersonDOB, @PersonImage, @PersonImageType)
End

下面就是完整的代码，拷贝即可运行：

Dim ImageStream As Stream
' 获得图片的大小

' 获得图片类型
strImageType = PersonImage.PostedFile.ContentType
'读取图片
ImageStream = PersonImage.PostedFile.InputStream
Dim ImageContent(intImageSize) As Byte
Dim intStatus As Integer
intStatus = ImageStream.Read(ImageContent, 0, intImageSize)
' 创建Connection和Command对象

Dim myConnection As New SqlConnection(strCnn)

' 向存储过程添加参数

myCommand.Parameters.Add(prmEmail)

Dim prmName As New SqlParameter("@PersonName", SqlDbType.VarChar, 255)
prmName.Value = txtPersonName.Text
myCommand.Parameters.Add(prmName)
Dim prmSex As New SqlParameter("@PersonSex", SqlDbType.Char, 1)

If sexMale.Checked Then
prmSex.Value = "M"
Else
prmSex.Value = "F"
End If

Dim prmPersonImage As New SqlParameter("@PersonImage", SqlDbType.Image)

myCommand.Parameters.Add(prmPersonImage)

Dim prmPersonImageType As New SqlParameter("@PersonImageType", SqlDbType.VarChar, 255)
prmPersonImageType.Value = strImageType
myCommand.Parameters.Add(prmPersonImageType)

Try
myConnection.Open()
myCommand.ExecuteNonQuery()
myConnection.Close()
Response.Write("添加成功！")
Catch SQLexc As SqlException
Response.Write("添加失败，原因：" & SQLexc.ToString())
End Try
End Sub
