如何访问一个二进制资源在C＃应用程序 [英] How to access a binary resource in a C# application

问题描述

我试图存储空Access数据库（.mdb）在我的应用程序的资源。然后我想写出来的文件系统，并与表定义填充它，等我在Visual Studio 2005中的问题，我的C＃应用​​程序是不能够访问存储在同一个程序集中的资源（我本来以为会是默认访问）。这是我的code：

I'm trying to store an empty Access database (.mdb) as a resource in my application. I then want to write it out the file system and populate it with table definitions, etc. The problem I'm having in Visual Studio 2005 and my C# application is with not being able to access the resource stored in the same assembly (which I would have thought would be accessible by default). Here's my code:

byte[] abytResource;
System.Reflection.Assembly objAssembly = System.Reflection.Assembly.GetExecutingAssembly();
objStream = objAssembly.GetManifestResourceStream("empty.mdb");
abytResource = new Byte[objStream.Length];
objStream.Read(abytResource, 0, (int)objStream.Length);
objFileStream = new FileStream(newDatabasePathWithName, FileMode.Create);
objFileStream.Write(abytResource, 0, (int)objStream.Length);
objFileStream.Close();

GetManifestResourceStream返回NULL，并根据那是因为资源必须是私有的（因为即使它不存在一个非返回NULL值）的文档。所以我的问题是这样的：

GetManifestResourceStream returns NULL and according to the documentation that's because the resource must be private (because even if it doesn't exist a non-NULL value is returned). So my question is this:

如何让我的资源访问自己的应用程序？我已经把它添加到项目中并标记为嵌入的资源，顺便说一句。

How do i make my resource accessible to my own application? I already added it to the project and marked it as "Embedded Resource", by the way.

谢谢！

推荐答案

您需要preFIX的empty.mdb与组件的默认命名空间。是这样的：

You need to prefix the "empty.mdb" with the default namespace of the assembly. Something like:

objStream = objAssembly.GetManifestResourceStream("My.Namespace.empty.mdb");
