从数据库中（SQL）中读取image字段
我用的是VS2005，试了好多次，总是不行，就是那个stream类在2005里好象用不了，是不是要导入哪个命名空间？     请高手指点，最好是能给代码     谢谢了啊！！急

------解决方案--------------------
using System.IO
------解决方案--------------------
FileStream Fs = new FileStream(Path, FileMode.OpenOrCreate, FileAccess.Read, FileShare.None);
byte[] MyBinData = new byte[Fs.Length];
Fs.Write(数据库Image字段, 0, Bytes.Length);
Fs.Close();

FileStream 在System.IO里
------解决方案--------------------
Dim sql As String = "Select * from ServiceAttachment where ServiceAttachmentKey= ' " & Attkey & " ' "
Dim comm As New SqlCommand(sql, cn)
Dim drr As System.Data.SqlClient.SqlDataReader = comm.ExecuteReader
If drr.Read Then
Dim imagedata As Byte() = CType(drr.Item( "DocumentData "), Byte())
SaveBytesToFile(filename, imagedata) ' ' 'function
End if
Public function SaveBytesToFile(ByVal strName As String, ByVal data As Byte())
Try
Dim fInfo As FileInfo = New FileInfo(strName)
If fInfo.Exists Then
fInfo.Delete()
End If
Dim fs As New FileStream(strName, FileMode.CreateNew)
Dim w As New BinaryWriter(fs)
w.Write(data)
w.Flush()
fs.Close()
Catch ee As Exception
Throw New Exception(ee.Message)
End Try
End Sub
