微软的SQL SERVER数据库的Image、text等字段都属于二进制的大对象。这些对象的存取和其他轻型对象略有不同。
微软.NET Framework的System.IO命名空间下给我们提供了一个FileStream文件流类。我们可以使用这个文件流对二进制大对象轻松进行读写。
我实现了一个简单的WinForm程序,这个程序通过点击“Open”按钮选择一个bmp或者jpg文件,并显示在图形控件PictureBox中。通过“Save”按钮存入数据库。点击“View”CheckBox可以切换到浏览状态,观看存入数据库的图片。
由于对二进制大对象使用的流操作,所以对于任何文件都具有通用性。读写文本文件也可以这么做。
-Microsoft s field and so on SQL SERVER database Image, text all
belongs to binary the big object. These objects deposits and
withdrawals and other light objects have the difference slightly.
MicrosoftNET Framework System.Under the IO naming space provided a FileStream document to us to flow
the kind. We may use this document to flow to the binary big object
with ease carry on read-write. I have realized a simple WinForm
procedure, this procedure through clicks on "Open" the button to
choose bmp or the jpg document, and the demonstration controls in
PictureBox in the graph. The button stores the database through
"Save". Clicks on "View" CheckBox to b

电子表格的输入和输出往往需要解决的问题。手术费。
Excel表格是输入输出经常需要涉及到的。操作Excel表格的方式也多种多样。比如,通过调用Excel程序的COM组件对Excel进行操作。但是,这种方式限制较多,且实现难度比较大。但是,用于访问数据库的组件ADO,是支持多种数据源的,其中就包括Excel文件。我们可以通过ADO组件对Excel文件进行读写访问。当然,在.NET平台上对应ADO数据访问组件的是ADO.NET组件。我编写的这个类就是通过ADO.NET实现了Excel文件的读写。由于时间仓促,功能还不是很完善,会在以后有时间的时候进行版本升级。也请各位高手多多批评指正。-Excel spreadsheet input and output is often of the need to address. Operation Excel variety of ways. For example, by calling the Excel COM procedures for the operation of Excel. However, this approach is more limited and more difficult to achieve. However, for access to the database components ADO, is to support multiple data sources, including Excel file. We can ADO components to read and write Excel files visit. Of course,.NET platform counterparts ADO data access components of ADO.NET components. I prepared this category is achieved through ADO.NET read and write Excel files. Because time is so short, the function is still not perfect, will in future have the time for version upgrades. Members also criticized many exp
