.net如何用二进制形式保存文件数据到数据库中？

[解决办法]
以下是将图片转化成二进制，其他的应该很好实现的，你参考一下
{
byte[] BlobData = null;
Bitmap picture;
FileStream stream;
stream = new FileStream(strFileName, FileMode.Open, FileAccess.Read);
BlobData = new byte[stream.Length];
stream.Read(BlobData, 0, (int)stream.Length);
picture = new Bitmap(stream);
stream.Close();
return BlobData;
}

用2进制流

字段定义为image类型，读取二进制文件到数据库中，则是byte[]，直接赋值存储就可以了
[解决办法]

C# code

 Dim intImageSize As Int64    Dim strImageType As String    Dim ImageStream As Stream    ' Gets the Size of the Image    intImageSize = PersonImage.PostedFile.ContentLength    ' Gets the Image Type    strImageType = PersonImage.PostedFile.ContentType    ' Reads the Image    ImageStream = PersonImage.PostedFile.InputStream    Dim ImageContent(intImageSize) As Byte    Dim intStatus As Integer    intStatus = ImageStream.Read(ImageContent, 0, intImageSize)    ' Create Instance of Connection and Command Object    Dim myConnection As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))    Dim myCommand As New SqlCommand("sp_person_isp", myConnection)    ' Mark the Command as a SPROC    myCommand.CommandType = CommandType.StoredProcedure    ' Add Parameters to SPROC    Dim prmPersonImage As New SqlParameter("@PersonImage", SqlDbType.Image)    prmPersonImage.Value = ImageContent    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("New person successfully added!")    Catch SQLexc As SqlException        Response.Write("Insert Failed. Error Details are: " & SQLexc.ToString())    End Try
